Detailed Description

Toplevel Window.

This represents all widgets which are physical windows controlled by the window manager.

The window will be hidden when the window manager's close button is clicked. Override on_delete_event() to stop this.

Gtk::manage() has no effect on Windows because they have no parent Containers.

Member Function Documentation

bool Gtk::Window::activate_default

(

)

Activates the default widget for the window, unless the current focused widget has been configured to receive the default action (see Gtk::Widget::set_receives_default()), in which case the focused widget is activated.

Returns

true if a widget got activated.

bool Gtk::Window::activate_focus

(

)

Activates the current focused widget within the window.

Returns

true if a widget got activated.

void Gtk::Window::add_accel_group

(

const Glib::RefPtr< AccelGroup >&

accel_group

)

Associate accel_group with window, such that calling gtk_accel_groups_activate() on window will activate accelerators in accel_group.

Parameters

accel_group

A Gtk::AccelGroup.

void Gtk::Window::add_mnemonic	(	guint	keyval,
		Widget&	target
	)

Adds a mnemonic to this window.

Parameters

keyval	The mnemonic.
target	The widget that gets activated by the mnemonic.

void Gtk::Window::begin_move_drag	(	int	button,
		int	root_x,
		int	root_y,
		guint32	timestamp
	)

Starts moving a window.

This function is used if an application has window movement grips. When GDK can support it, the window movement will be done using the standard mechanism for the [window manager][gtk-X11-arch] or windowing system. Otherwise, GDK will try to emulate window movement, potentially not all that well, depending on the windowing system.

Parameters

button	Mouse button that initiated the drag.
root_x	X position where the user clicked to initiate the drag, in root window coordinates.
root_y	Y position where the user clicked to initiate the drag.
timestamp	Timestamp from the click event that initiated the drag.

void Gtk::Window::begin_resize_drag	(	Gdk::WindowEdge	edge,
		int	button,
		int	root_x,
		int	root_y,
		guint32	timestamp
	)

Starts resizing a window.

This function is used if an application has window resizing controls. When GDK can support it, the resize will be done using the standard mechanism for the [window manager][gtk-X11-arch] or windowing system. Otherwise, GDK will try to emulate window resizing, potentially not all that well, depending on the windowing system.

Parameters

button	Mouse button that initiated the drag.
edge	Position of the resize control.
root_x	X position where the user clicked to initiate the drag, in root window coordinates.
root_y	Y position where the user clicked to initiate the drag.
timestamp	Timestamp from the click event that initiated the drag.

void Gtk::Window::close

(

)

Requests that the window is closed, similar to what happens when a window manager close button is clicked.

This function can be used with close buttons in custom titlebars.

Since gtkmm 3.10:

void Gtk::Window::deiconify

(

)

Asks to deiconify (i.e. unminimize) the specified window.

Note that you shouldn’t assume the window is definitely deiconified afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch])) could iconify it again before your code which assumes deiconification gets to run.

You can track iconification via the “window-state-event” signal on Gtk::Widget.

void Gtk::Window::destroy_ ( )

protected

void Gtk::Window::fullscreen

(

)

Asks to place window in the fullscreen state.

Note that you shouldn’t assume the window is definitely full screen afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could unfullscreen it again, and not all window managers honor requests to fullscreen windows. But normally the window will end up fullscreen. Just don’t write code that crashes if not.

You can track the fullscreen state via the “window-state-event” signal on Gtk::Widget.

Since gtkmm 2.2:

void Gtk::Window::fullscreen_on_monitor	(	const Glib::RefPtr< Gdk::Screen >&	screen,
		int	monitor

You can track the fullscreen state via the "window-state-event" signal on Gtk::Widget.

Since gtkmm 3.18:

Parameters

screen	A Gdk::Screen to draw to.
monitor	Which monitor to go fullscreen on.

void Gtk::Window::get_position	(	int &	root_x,
		int &	root_y
	)		const

This function returns the position you need to pass to move() to keep window in its current position.

This means that the meaning of the returned value varies with window gravity. See move() for more details.

The reliability of this function depends on the windowing system currently in use. Some windowing systems, such as Wayland, do not support a global coordinate system, and thus the position of the window will always be (0, 0). Others, like X11, do not have a reliable way to obtain the geometry of the decorations of a window if they are provided by the window manager. Additionally, on X11, window manager have been known to mismanage window gravity, which result in windows moving even if you use the coordinates of the current position as returned by this function.

If you haven’t changed the window gravity, its gravity will be Gdk::GRAVITY_NORTH_WEST. This means that get_position() gets the position of the top-left corner of the window manager frame for the window. move() sets the position of this same top-left corner.

If a window has gravity Gdk::GRAVITY_STATIC the window manager frame is not relevant, and thus get_position() will always produce accurate results. However you can’t use static gravity to do things like place a window in a corner of the screen, because static gravity ignores the window manager decorations.

Ideally, this function should return appropriate values if the window has client side decorations, assuming that the windowing system supports global coordinates.

In practice, saving the window position should not be left to applications, as they lack enough knowledge of the windowing system and the window manager state to effectively do so. The appropriate way to implement saving the window position is to use a platform-specific protocol, wherever that is available.

Parameters

root_x	Return location for X coordinate of gravity-determined reference point.
root_y	Return location for Y coordinate of gravity-determined reference point.

bool Gtk::Window::get_resizable

Obtains the current size of window.

If window is not onscreen, it returns the size GTK+ will suggest to the [window manager][gtk-X11-arch] for the initial window size (but this is not reliably the same as the size the window manager will actually select). The size obtained by get_size() is the last size received in a Gdk::EventConfigure, that is, GTK+ uses its locally-stored size, rather than querying the X server for the size. As a result, if you call resize() then immediately call get_size(), the size won’t have taken effect yet. After the window manager processes the resize request, GTK+ receives notification that the size has changed via a configure event, and the size of the window gets updated.

Note

Nearly any use of this function creates a race condition, because the size of the window may change between the time that you get the size and the time that you perform some action assuming that size is the current size. To avoid race conditions, connect to “configure-event” on the window and adjust your size-dependent state to match the size delivered in the Gdk::EventConfigure.

The returned size does not include the size of the window manager decorations (aka the window frame or border). Those are not drawn by GTK+ and GTK+ has no reliable method of determining their size.

If you are getting a window size in order to position the window onscreen, there may be a better way. The preferred way is to simply set the window’s semantic type with set_type_hint(), which allows the window manager to e.g. center dialogs. Also, if you set the transient parent of dialogs with set_transient_for() window managers will often center the dialog over its parent window. It's much preferred to let the window manager handle these things rather than doing it yourself, because all apps will behave consistently and according to user prefs if the window manager handles it. Also, the window manager can take the size of the window decorations/border into account, while your application cannot.

When using client side decorations, GTK+ will do its best to adjust the returned values to match the logical size of the window excluding the widgets added for client side decorations, but there is no garantee that the result will be totally accurate because these widgets depend on the theme and may not be realized or visible at the time get_size() is invoked.

In any case, if you insist on application-specified window positioning, there’s still a better way than doing it yourself - set_position() will frequently handle the details for you.

true if window is urgent.

WindowType Gtk::Window::get_window_type

(

)

Returns

true if window has an explicit window group.

bool Gtk::Window::has_toplevel_focus

(

)

const

Returns whether the input focus is within this GtkWindow.

For real toplevel windows, this is identical to is_active(), but for embedded windows, like Gtk::Plug, the results will differ.

Since gtkmm 2.4:

Returns

true if the input focus is within this GtkWindow.

void Gtk::Window::iconify

(

)

Asks to iconify (i.e. minimize) the specified window.

Note that you shouldn’t assume the window is definitely iconified afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could deiconify it again, or there may not be a window manager in which case iconification isn’t possible, etc. But normally the window will end up iconified. Just don’t write code that crashes if not.

It’s permitted to call this function before showing a window, in which case the window will be iconified before it ever appears onscreen.

You can track iconification via the “window-state-event” signal on Gtk::Widget.

bool Gtk::Window::is_active

(

)

const

Returns whether the window is part of the current active toplevel.

(That is, the toplevel window receiving keystrokes.) The return value is true if the window is active toplevel itself, but also if it is, say, a Gtk::Plug embedded in the active toplevel. You might use this function if you wanted to draw a widget differently in an active window from a widget in an inactive window. See has_toplevel_focus()

Since gtkmm 2.4:

Returns

true if the window part of the current active window.

bool Gtk::Window::is_maximized

(

)

const

Retrieves the current maximized state of window.

Note that since maximization is ultimately handled by the window manager and happens asynchronously to an application request, you shouldn’t assume the return value of this function changing immediately (or at all), as an effect of calling maximize() or unmaximize().

Since gtkmm 3.12:

Returns

Whether the window has a maximized state.

static std::vector<Window*> Gtk::Window::list_toplevels ( )

static

Returns a list of all existing toplevel windows.

The widgets in the list are not individually referenced. If you want to iterate through the list and perform actions involving callbacks that might destroy the widgets, you must call g_list_foreach (result, (GFunc)g_object_ref, <tt>nullptr</tt>) first, and then unref all the widgets afterwards.

Returns

List of toplevel widgets.

void Gtk::Window::maximize

(

)

Asks to maximize window, so that it becomes full-screen.

Note that you shouldn’t assume the window is definitely maximized afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could unmaximize it again, and not all window managers support maximization. But normally the window will end up maximized. Just don’t write code that crashes if not.

It’s permitted to call this function before showing a window, in which case the window will be maximized when it appears onscreen initially.

You can track maximization via the “window-state-event” signal on Gtk::Widget, or by listening to notifications on the Gtk::Window::property_is_maximized() property.

bool Gtk::Window::mnemonic_activate	(	guint	keyval,
		Gdk::ModifierType	modifier
	)

Activates the targets associated with the mnemonic.

Parameters

keyval	The mnemonic.
modifier	The modifiers.

Returns

true if the activation is done.

void Gtk::Window::move	(	int	x,
		int	y
	)

Asks the [window manager][gtk-X11-arch] to move window to the given position.

Window managers are free to ignore this; most window managers ignore requests for initial window positions (instead using a user-defined placement algorithm) and honor requests after the window has already been shown.

Note

the position is the position of the gravity-determined reference point for the window. The gravity determines two things: first, the location of the reference point in root window coordinates; and second, which point on the window is positioned at the reference point.

By default the gravity is Gdk::GRAVITY_NORTH_WEST, so the reference point is simply the x, y supplied to move(). The top-left corner of the window decorations (aka window frame or border) will be placed at x, y. Therefore, to position a window at the top left of the screen, you want to use the default gravity (which is Gdk::GRAVITY_NORTH_WEST) and move the window to 0,0.

To position a window at the bottom right corner of the screen, you would set Gdk::GRAVITY_SOUTH_EAST, which means that the reference point is at x + the window width and y + the window height, and the bottom-right corner of the window border will be placed at that reference point. So, to place a window in the bottom right corner you would first set gravity to south east, then write: gtk_window_move (window, gdk_screen_width() - window_width, gdk_screen_height() - window_height) (note that this example does not take multi-head scenarios into account).

The Extended Window Manager Hints Specification has a nice table of gravities in the “implementation notes” section.

The get_position() documentation may also be relevant.

Parameters

x	X coordinate to move window to.
y	Y coordinate to move window to.

virtual void Gtk::Window::on_set_focus ( Widget*  focus )

protectedvirtual

This is a default handler for the signal signal_set_focus().

Window& Gtk::Window::operator= ( Window&&  src )

noexcept

Window& Gtk::Window::operator= ( const Window&  )

delete

bool Gtk::Window::parse_geometry

(

const Glib::ustring &

geometry

)

Parses a standard X Window System geometry string - see the manual page for X (type “man X”) for details on this.

parse_geometry() does work on all GTK+ ports including Win32 but is primarily intended for an X environment.

If either a size or a position can be extracted from the geometry string, parse_geometry() returns true and calls set_default_size() and/or move() to resize/move the window.

If parse_geometry() returns true, it will also set the Gdk::HINT_USER_POS and/or Gdk::HINT_USER_SIZE hints indicating to the window manager that the size/position of the window was user-specified. This causes most window managers to honor the geometry.

Note that for parse_geometry() to work as expected, it has to be called when the window has its “final” size, i.e. after calling Gtk::Widget::show_all() on the contents and set_geometry_hints() on the window.

[C example ellipted]

Deprecated: 3.20: Geometry handling in GTK is deprecated.

Deprecated:

Geometry handling in GTK is deprecated.

Parameters

geometry

Geometry string.

Returns

true if string was parsed successfully.

void Gtk::Window::present

(

)

Presents a window to the user.

This may mean raising the window in the stacking order, deiconifying it, moving it to the current desktop, and/or giving it the keyboard focus, possibly dependent on the user’s platform, window manager, and preferences.

If window is hidden, this function calls Gtk::Widget::show() as well.

This function should be used when the user tries to open a window that’s already open. Say for example the preferences dialog is currently open, and the user chooses Preferences from the menu a second time; use present() to move the already-open dialog where the user can see it.

If you are calling this function in response to a user interaction, it is preferable to use present_with_time().

void Gtk::Window::present

(

guint32

timestamp

)

Presents a window to the user in response to a user interaction.

If you need to present a window without a timestamp, use present(). See present() for details.

void Gtk::Window::reshow_with_initial_size

(

)

Hides window, then reshows it, resetting the default size and position of the window.

Used by GUI builders only.

Deprecated: 3.10: GUI builders can call Gtk::Widget::hide(), Gtk::Widget::unrealize() and then Gtk::Widget::show() on window themselves, if they still need this functionality.

Deprecated:

GUI builders can call Widget::hide(), Widget::unrealize() and then Widget::show() themselves, if they still need this functionality.

void Gtk::Window::resize	(	int	width,
		int	height
	)

Resizes the window as if the user had done so, obeying geometry constraints.

The default geometry constraint is that windows may not be smaller than their size request; to override this constraint, call Gtk::Widget::set_size_request() to set the window's request to a smaller value.

If resize() is called before showing a window for the first time, it overrides any default size set with set_default_size().

Windows may not be resized smaller than 1 by 1 pixels.

When using client side decorations, GTK+ will do its best to adjust the given size so that the resulting window size matches the requested size without the title bar, borders and shadows added for the client side decorations, but there is no garantee that the result will be totally accurate because these widgets added for client side decorations depend on the theme and may not be realized or visible at the time resize() is issued.

Typically, resize() will compensate for the GtkHeaderBar height only if it's known at the time the resulting GtkWindow configuration is issued. For example, if new widgets are added after the GtkWindow configuration and cause the GtkHeaderBar to grow in height, this will result in a window content smaller that specified by resize() and not a larger window.

Parameters

width	Width in pixels to resize the window to.
height	Height in pixels to resize the window to.

void Gtk::Window::resize_to_geometry	(	int	width,
		int	height
	)

Like resize(), but width and height are interpreted in terms of the base size and increment set with gtk_window_set_geometry_hints.

Since gtkmm 3.0:

Deprecated: 3.20: This function does nothing. Use resize() and compute the geometry yourself.

Deprecated:

This function does nothing. Use resize() and compute the geometry yourself.

Parameters

width	Width in resize increments to resize the window to.
height	Height in resize increments to resize the window to.

void Gtk::Window::set_accept_focus

(

bool

setting = true

)

Windows may set a hint asking the desktop environment not to receive the input focus.

This function sets this hint.

Since gtkmm 2.4:

Parameters

setting

true to let this window receive input focus.

void Gtk::Window::set_application

(

const Glib::RefPtr< Application >&

application

)

Sets or unsets the Gtk::Application associated with the window.

The application will be kept alive for at least as long as the window is open.

Since gtkmm 3.0:

Parameters

application

A Gtk::Application, or nullptr.

void Gtk::Window::set_attached_to

(

Widget&

attach_widget

)

Marks window as attached to attach_widget.

This creates a logical binding between the window and the widget it belongs to, which is used by GTK+ to propagate information such as styling or accessibility to window as if it was a children of attach_widget.

Examples of places where specifying this relation is useful are for instance a Gtk::Menu created by a Gtk::ComboBox, a completion popup window created by Gtk::Entry or a typeahead search entry created by Gtk::TreeView.

Note that this function should not be confused with set_transient_for(), which specifies a window manager relation between two toplevels instead.

Passing nullptr for attach_widget detaches the window.

Since gtkmm 3.4:

Parameters

attach_widget

A Gtk::Widget, or nullptr.

static void Gtk::Window::set_auto_startup_notification ( bool  setting = true )

static

By default, after showing the first Gtk::Window, GTK+ calls gdk_notify_startup_complete().

Call this function to disable the automatic startup notification. You might do this if your first window is a splash screen, and you want to delay notification until after your real main window has been shown, for example.

In that example, you would disable startup notification temporarily, show your splash screen, then re-enable it so that showing the main window would automatically result in notification.

Since gtkmm 2.2:

Parameters

setting

true to automatically do startup notification.

void Gtk::Window::set_decorated

(

bool

setting = true

)

By default, windows are decorated with a title bar, resize controls, etc.

Some [window managers][gtk-X11-arch] allow GTK+ to disable these decorations, creating a borderless window. If you set the decorated property to false using this function, GTK+ will do its best to convince the window manager not to decorate the window. Depending on the system, this function may not have any effect when called on a window that is already visible, so you should call it before calling Gtk::Widget::show().

On Windows, this function always works, since there’s no window manager policy involved.

Parameters

setting

true to decorate the window.

void Gtk::Window::set_default

(

Gtk::Widget&

default_widget

)

The default widget is the widget that's activated when the user presses Enter in a dialog (for example).

This function sets the default widget for a Gtk::Window. When setting (rather than unsetting) the default widget it's generally easier to call Gtk::Widget::grab_focus() on the widget. Before making a widget the default widget, you must set the Gtk::CAN_DEFAULT flag on the widget you'd like to make the default using GTK_WIDGET_SET_FLAGS().

Parameters

default_widget

Widget to be the default.

void Gtk::Window::set_default_geometry	(	int	width,
		int	height
	)

Like set_default_size(), but width and height are interpreted in terms of the base size and increment set with gtk_window_set_geometry_hints.

Since gtkmm 3.0:

Deprecated: 3.20: This function does nothing. If you want to set a default size, use set_default_size() instead.

Deprecated:

This function does nothing. If you want to set a default size, use set_default_size() instead.

Parameters

width	Width in resize increments, or -1 to unset the default width.
height	Height in resize increments, or -1 to unset the default height.

static void Gtk::Window::set_default_icon ( const Glib::RefPtr< Gdk::Pixbuf >&  icon )

static

Sets an icon to be used as fallback for windows that haven't had set_icon() called on them from a pixbuf.

Since gtkmm 2.4:

Parameters

icon

The icon.

static bool Gtk::Window::set_default_icon_from_file ( const std::string &  filename )

static

Sets an icon to be used as fallback for windows that haven't had set_icon_list() called on them from a file on disk.

Warns on failure if err is nullptr.

Since gtkmm 2.2:

Parameters

filename

Location of icon file.

Returns

true if setting the icon succeeded.

static void Gtk::Window::set_default_icon_list ( const std::vector< Glib::RefPtr< Gdk::Pixbuf > >&  list )

static

Sets an icon list to be used as fallback for windows that haven't had set_icon_list() called on them to set up a window-specific icon list.

This function allows you to set up the icon for all windows in your app at once.

See set_icon_list() for more details.

Parameters

list	A list of Gdk::Pixbuf.

static void Gtk::Window::set_default_icon_name ( const Glib::ustring &  name )

static

Sets an icon to be used as fallback for windows that haven't had set_icon_list() called on them from a named themed icon, see set_icon_name().

Since gtkmm 2.6:

Parameters

name	The name of the themed icon.

void Gtk::Window::set_default_size	(	int	width,
		int	height
	)

Sets the default size of a window.

If the window’s “natural” size (its size request) is larger than the default, the default will be ignored. More generally, if the default size does not obey the geometry hints for the window (set_geometry_hints() can be used to set these explicitly), the default size will be clamped to the nearest permitted size.

Unlike Gtk::Widget::set_size_request(), which sets a size request for a widget and thus would keep users from shrinking the window, this function only sets the initial size, just as if the user had resized the window themselves. Users can still shrink the window again as they normally would. Setting a default size of -1 means to use the “natural” default size (the size request of the window).

For more control over a window’s initial size and how resizing works, investigate set_geometry_hints().

For some uses, resize() is a more appropriate function. resize() changes the current size of the window, rather than the size to be used on initial display. resize() always affects the window itself, not the geometry widget.

The default size of a window only affects the first time a window is shown; if a window is hidden and re-shown, it will remember the size it had prior to hiding, rather than using the default size.

Windows can’t actually be 0x0 in size, they must be at least 1x1, but passing 0 for width and height is OK, resulting in a 1x1 default size.

If you use this function to reestablish a previously saved window size, note that the appropriate size to save is the one returned by get_size(). Using the window allocation directly will not work in all circumstances and can lead to growing or shrinking windows.

Parameters

width	Width in pixels, or -1 to unset the default width.
height	Height in pixels, or -1 to unset the default height.

void Gtk::Window::set_deletable

(

bool

setting = true

)

By default, windows have a close button in the window frame.

Some [window managers][gtk-X11-arch] allow GTK+ to disable this button. If you set the deletable property to false using this function, GTK+ will do its best to convince the window manager not to show a close button. Depending on the system, this function may not have any effect when called on a window that is already visible, so you should call it before calling Gtk::Widget::show().

On Windows, this function always works, since there’s no window manager policy involved.

Since gtkmm 2.10:

Parameters

setting

true to decorate the window as deletable.

void Gtk::Window::set_focus

(

Gtk::Widget&

focus

)

If focus is not the current focus widget, and is focusable, sets it as the focus widget for the window.

To set the focus to a particular widget in the toplevel, it is usually more convenient to use Gtk::Widget::grab_focus() instead of this function.

Parameters

focus

Widget to be the new focus widget.

void Gtk::Window::set_focus_on_map

(

bool

setting = true

)

Windows may set a hint asking the desktop environment not to receive the input focus when the window is mapped.

This function sets this hint.

Since gtkmm 2.6:

Parameters

setting

true to let this window receive input focus on map.

void Gtk::Window::set_focus_visible

(

bool

setting = true

)

Sets the Gtk::Window::property_focus_visible() property.

Since gtkmm 3.2:

Parameters

setting

The new value.

void Gtk::Window::set_geometry_hints	(	Widget&	geometry_widget,
		const Gdk::Geometry&	geometry,
		Gdk::WindowHints	geom_mask
	)

This function sets up hints about how a window can be resized by the user.

You can set a minimum and maximum size; allowed resize increments (e.g. for xterm, you can only resize by the size of a character); aspect ratios; and more. See the Gdk::Geometry struct.

Parameters

geometry_widget	Widget the geometry hints used to be applied to or nullptr. Since 3.20 this argument is ignored and GTK behaves as if nullptr was set.
geometry	Struct containing geometry information or nullptr.
geom_mask	Mask indicating which struct fields should be paid attention to.

void Gtk::Window::set_gravity

(

Gdk::Gravity

gravity

)

Window gravity defines the meaning of coordinates passed to move().

See move() and Gdk::Gravity for more details.

The default window gravity is Gdk::GRAVITY_NORTH_WEST which will typically “do what you mean.”

Parameters

gravity

Window gravity.

void Gtk::Window::set_has_resize_grip

(

bool

value = true

)

Sets whether window has a corner resize grip.

Note that the resize grip is only shown if the window is actually resizable and not maximized. Use resize_grip_is_visible() to find out if the resize grip is currently shown.

Since gtkmm 3.0:

Deprecated: 3.14: Resize grips have been removed.

Deprecated:

Resize grips have been removed.

Parameters

value

true to allow a resize grip.

void Gtk::Window::set_hide_titlebar_when_maximized

(

bool

setting = true

)

If setting is true, then window will request that it’s titlebar should be hidden when maximized.

This is useful for windows that don’t convey any information other than the application name in the titlebar, to put the available screen space to better use. If the underlying window system does not support the request, the setting will not have any effect.

Note that custom titlebars set with set_titlebar() are not affected by this. The application is in full control of their content and visibility anyway.

Since gtkmm 3.4:

Parameters

setting

Whether to hide the titlebar when window is maximized.

void Gtk::Window::set_icon

(

const Glib::RefPtr< Gdk::Pixbuf >&

icon

)

Sets up the icon representing a Gtk::Window.

This icon is used when the window is minimized (also known as iconified). Some window managers or desktop environments may also place it in the window frame, or display it in other contexts. On others, the icon is not used at all, so your mileage may vary.

The icon should be provided in whatever size it was naturally drawn; that is, don’t scale the image before passing it to GTK+. Scaling is postponed until the last minute, when the desired final size is known, to allow best quality.

If you have your icon hand-drawn in multiple sizes, use set_icon_list(). Then the best size will be used.

This function is equivalent to calling set_icon_list() with a 1-element list.

See also set_default_icon_list() to set the icon for all windows in your application in one go.

Parameters

icon	Icon image, or nullptr.

bool Gtk::Window::set_icon_from_file

(

const std::string &

filename

)

Sets the icon for the window.

This function is equivalent to calling set_icon() with a pixbuf created by loading the image from filename.

Parameters

filename

Location of icon file.

Returns

true if setting the icon succeeded.

void Gtk::Window::set_icon_list

(

const std::vector< Glib::RefPtr< Gdk::Pixbuf > >&

list

)

Sets up the icon representing a Gtk::Window.

The icon is used when the window is minimized (also known as iconified). Some window managers or desktop environments may also place it in the window frame, or display it in other contexts. On others, the icon is not used at all, so your mileage may vary.

set_icon_list() allows you to pass in the same icon in several hand-drawn sizes. The list should contain the natural sizes your icon is available in; that is, don’t scale the image before passing it to GTK+. Scaling is postponed until the last minute, when the desired final size is known, to allow best quality.

By passing several sizes, you may improve the final image quality of the icon, by reducing or eliminating automatic image scaling.

Recommended sizes to provide: 16x16, 32x32, 48x48 at minimum, and larger images (64x64, 128x128) if you have them.

See also set_default_icon_list() to set the icon for all windows in your application in one go.

Note that transient windows (those who have been set transient for another window using set_transient_for()) will inherit their icon from their transient parent. So there’s no need to explicitly set the icon on transient windows.

Parameters

list	List of Gdk::Pixbuf.

void Gtk::Window::set_icon_name

(

const Glib::ustring &

name

)

Sets the icon for the window from a named themed icon.

See the docs for Gtk::IconTheme for more details. On some platforms, the window icon is not used at all.

Note that this has nothing to do with the WM_ICON_NAME property which is mentioned in the ICCCM.

Since gtkmm 2.6:

Parameters

name	The name of the themed icon.

void Gtk::Window::set_keep_above

(

bool

setting = true

)

Asks to keep window above, so that it stays on top.

Note that you shouldn’t assume the window is definitely above afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could not keep it above, and not all window managers support keeping windows above. But normally the window will end kept above. Just don’t write code that crashes if not.

It’s permitted to call this function before showing a window, in which case the window will be kept above when it appears onscreen initially.

You can track the above state via the “window-state-event” signal on Gtk::Widget.

Note that, according to the Extended Window Manager Hints Specification, the above state is mainly meant for user preferences and should not be used by applications e.g. for drawing attention to their dialogs.

Since gtkmm 2.4:

Parameters

setting

Whether to keep window above other windows.

void Gtk::Window::set_keep_below

(

bool

setting = true

)

Asks to keep window below, so that it stays in bottom.

Note that you shouldn’t assume the window is definitely below afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could not keep it below, and not all window managers support putting windows below. But normally the window will be kept below. Just don’t write code that crashes if not.

It’s permitted to call this function before showing a window, in which case the window will be kept below when it appears onscreen initially.

You can track the below state via the “window-state-event” signal on Gtk::Widget.

Note that, according to the Extended Window Manager Hints Specification, the above state is mainly meant for user preferences and should not be used by applications e.g. for drawing attention to their dialogs.

Since gtkmm 2.4:

Parameters

setting

Whether to keep window below other windows.

void Gtk::Window::set_manage ( )

override

Overriden to warn that it doesn't make sense to use Gtk::manage() on this class because it has no parent container.

void Gtk::Window::set_mnemonic_modifier

(

Gdk::ModifierType

modifier

)

Sets the mnemonic modifier for this window.

Parameters

modifier

The modifier mask used to activate mnemonics on this window.

void Gtk::Window::set_mnemonics_visible

(

bool

setting = true

)

Sets the Gtk::Window::property_mnemonics_visible() property.

Since gtkmm 2.20:

Parameters

setting

The new value.

void Gtk::Window::set_modal

(

bool

modal = true

)

Sets a window modal or non-modal.

Modal windows prevent interaction with other windows in the same application. To keep modal dialogs on top of main application windows, use set_transient_for() to make the dialog transient for the parent; most [window managers][gtk-X11-arch] will then disallow lowering the dialog below the parent.

Parameters

modal

Whether the window is modal.

void Gtk::Window::set_opacity

(

double

opacity

)

Request the windowing system to make window partially transparent, with opacity 0 being fully transparent and 1 fully opaque.

(Values of the opacity parameter are clamped to the [0,1] range.) On X11 this has any effect only on X screens with a compositing manager running. See Gtk::Widget::is_composited(). On Windows it should work always.

Note that setting a window’s opacity after the window has been shown causes it to flicker once on Windows.

Since gtkmm 2.12:

Deprecated: 3.8: Use gtk_widget_set_opacity instead.

Deprecated:

Use Widget::set_opacity() instead.

Parameters

opacity

Desired opacity, between 0 and 1.

void Gtk::Window::set_position

(

WindowPosition

position

)

Sets a position constraint for this window.

If the old or new constraint is Gtk::WIN_POS_CENTER_ALWAYS, this will also cause the window to be repositioned to satisfy the new constraint.

Parameters

position

A position constraint.

void Gtk::Window::set_resizable

(

bool

resizable = true

)

Sets whether the user can resize a window.

Windows are user resizable by default.

Parameters

resizable

true if the user can resize this window.

void Gtk::Window::set_role

(

const Glib::ustring &

role

)

This function is only useful on X11, not with other GTK+ targets.

In combination with the window title, the window role allows a [window manager][gtk-X11-arch] to identify "the same" window when an application is restarted. So for example you might set the “toolbox” role on your app’s toolbox window, so that when the user restarts their session, the window manager can put the toolbox back in the same place.

If a window already has a unique title, you don’t need to set the role, since the WM can use the title to identify the window when restoring the session.

Parameters

role	Unique identifier for the window to be used when restoring a session.

void Gtk::Window::set_screen

(

const Glib::RefPtr< Gdk::Screen >&

screen

)

Sets the Gdk::Screen where the window is displayed; if the window is already mapped, it will be unmapped, and then remapped on the new screen.

Since gtkmm 2.2:

Parameters

screen

A Gdk::Screen.

void Gtk::Window::set_skip_pager_hint

(

bool

setting = true

)

Windows may set a hint asking the desktop environment not to display the window in the pager.

This function sets this hint. (A "pager" is any desktop navigation tool such as a workspace switcher that displays a thumbnail representation of the windows on the screen.)

Since gtkmm 2.2:

Parameters

setting

true to keep this window from appearing in the pager.

void Gtk::Window::set_skip_taskbar_hint

(

bool

setting = true

)

Windows may set a hint asking the desktop environment not to display the window in the task bar.

This function sets this hint.

Since gtkmm 2.2:

Parameters

setting

true to keep this window from appearing in the task bar.

void Gtk::Window::set_startup_id

(

const Glib::ustring &

startup_id

)

Startup notification identifiers are used by desktop environment to track application startup, to provide user feedback and other features.

This function changes the corresponding property on the underlying GdkWindow. Normally, startup identifier is managed automatically and you should only use this function in special cases like transferring focus from other processes. You should use this function before calling present() or any equivalent function generating a window map event.

This function is only useful on X11, not with other GTK+ targets.

Since gtkmm 2.12:

Parameters

startup_id

A string with startup-notification identifier.

void Gtk::Window::set_title

(

const Glib::ustring &

title

)

Sets the title of the Gtk::Window.

The title of a window will be displayed in its title bar; on the X Window System, the title bar is rendered by the [window manager][gtk-X11-arch], so exactly how the title appears to users may vary according to a user’s exact configuration. The title should help a user distinguish this window from other windows they may have open. A good title might include the application name and current document filename, for example.

Parameters

title

Title of the window.

void Gtk::Window::set_titlebar

(

Widget&

titlebar

)

Sets a custom titlebar for window.

If you set a custom titlebar, GTK+ will do its best to convince the window manager not to put its own titlebar on the window. Depending on the system, this function may not work for a window that is already visible, so you set the titlebar before calling Gtk::Widget::show().

Since gtkmm 3.10:

Parameters

titlebar

The widget to use as titlebar.

void Gtk::Window::set_transient_for

(

Window&

parent

)

Dialog windows should be set transient for the main application window they were spawned from.

This allows [window managers][gtk-X11-arch] to e.g. keep the dialog on top of the main window, or center the dialog over the main window. Gtk::Dialog::new_with_buttons() and other convenience functions in GTK+ will sometimes call set_transient_for() on your behalf.

Passing nullptr for parent unsets the current transient window.

On Wayland, this function can also be used to attach a new Gtk::WINDOW_POPUP to a Gtk::WINDOW_TOPLEVEL parent already mapped on screen so that the Gtk::WINDOW_POPUP will be created as a subsurface-based window Gdk::WINDOW_SUBSURFACE which can be positioned at will relatively to the Gtk::WINDOW_TOPLEVEL surface.

On Windows, this function puts the child window on top of the parent, much as the window manager would have done on X.

Parameters

parent

Parent window, or nullptr.

void Gtk::Window::set_type_hint

(

Gdk::WindowTypeHint

hint

)

By setting the type hint for the window, you allow the window manager to decorate and handle the window in a way which is suitable to the function of the window in your application.

This function should be called before the window becomes visible.

Gtk::Dialog::new_with_buttons() and other convenience functions in GTK+ will sometimes call set_type_hint() on your behalf.

Parameters

hint	The window type.

void Gtk::Window::set_urgency_hint

(

bool

setting = true

)

Windows may set a hint asking the desktop environment to draw the users attention to the window.

This function sets this hint.

Since gtkmm 2.8:

Parameters

setting

true to mark this window as urgent.

void Gtk::Window::set_wmclass	(	const Glib::ustring &	wmclass_name,
		const Glib::ustring &	wmclass_class
	)

Don’t use this function.

It sets the X Window System “class” and “name” hints for a window. According to the ICCCM, you should always set these to the same value for all windows in an application, and GTK+ sets them to that value by default, so calling this function is sort of pointless. However, you may want to call set_role() on each window in your application, for the benefit of the session manager. Setting the role allows the window manager to restore window positions when loading a saved session.

Parameters

wmclass_name	Window name hint.
wmclass_class	Window class hint.

Glib::SignalProxy< void > Gtk::Window::signal_keys_changed

(

)

Slot Prototype:

void on_my_keys_changed()

The signal_keys_changed() signal gets emitted when the set of accelerators or mnemonics that are associated with window changes.

Glib::SignalProxy< void,Widget* > Gtk::Window::signal_set_focus

(

)

Slot Prototype:

void on_my_set_focus(Widget* focus)

void Gtk::Window::stick

(

)

Asks to stick window, which means that it will appear on all user desktops.

Note that you shouldn’t assume the window is definitely stuck afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch] could unstick it again, and some window managers do not support sticking windows. But normally the window will end up stuck. Just don't write code that crashes if not.

It’s permitted to call this function before showing a window.

You can track stickiness via the “window-state-event” signal on Gtk::Widget.

void Gtk::Window::unfullscreen

(

)

Asks to toggle off the fullscreen state for window.

Note that you shouldn’t assume the window is definitely not full screen afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could fullscreen it again, and not all window managers honor requests to unfullscreen windows. But normally the window will end up restored to its normal state. Just don’t write code that crashes if not.

You can track the fullscreen state via the “window-state-event” signal on Gtk::Widget.

Since gtkmm 2.2:

void Gtk::Window::unmaximize

(

)

Asks to unmaximize window.

Note that you shouldn’t assume the window is definitely unmaximized afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could maximize it again, and not all window managers honor requests to unmaximize. But normally the window will end up unmaximized. Just don’t write code that crashes if not.

You can track maximization via the “window-state-event” signal on Gtk::Widget.

void Gtk::Window::unset_application

(

)

Unsets the Application associated with the window.

This could cause the application to exit if it is the application's last window.

void Gtk::Window::unset_attached_to

Since gtkmm 2.20:

void Gtk::Window::unstick

(

)

Asks to unstick window, which means that it will appear on only one of the user’s desktops.

Note that you shouldn’t assume the window is definitely unstuck afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could stick it again. But normally the window will end up stuck. Just don’t write code that crashes if not.
