Detailed Description

Infinite scrollable area containing child widgets and/or custom drawing.

Gtk::Layout is similar to Gtk::DrawingArea in that it's a "blank slate" and doesn't do anything but paint a blank background by default. It's different in that it supports scrolling natively (You can add it directly to a Gtk::ScrolledWindow), and it can contain child widgets, since it's a Gtk::Container. However if you're just going to draw, a Gtk::DrawingArea is a better choice since it has lower overhead.

Member Function Documentation

Glib::RefPtr<Gdk::Window> Gtk::Layout::get_bin_window

(

)

Retrieve the bin window of the layout used for drawing operations.

Since gtkmm 2.14:

Returns:

A Gdk::Window.

Glib::RefPtr<const Gdk::Window> Gtk::Layout::get_bin_window

(

)

const

Retrieve the bin window of the layout used for drawing operations.

Since gtkmm 2.14:

Returns:

A Gdk::Window.

void Gtk::Layout::get_size	(	guint &	width,
		guint &	height
	)		const

Gets the size that has been set on the layout, and that determines the total extents of the layout's scrollbar area.

See set_size().

Parameters:

width	Location to store the width set on layout, or 0.
height	Location to store the height set on layout, or 0.

const GtkLayout* Gtk::Layout::gobj

(

)

const [inline]

Provides access to the underlying C GtkObject.

Reimplemented from Gtk::Container.

GtkLayout* Gtk::Layout::gobj

(

)

[inline]

Provides access to the underlying C GtkObject.

Reimplemented from Gtk::Container.

void Gtk::Layout::move	(	Widget&	child_widget,
		int	x,
		int	y
	)

Moves a current child of layout to a new position.

Parameters:

child_widget	A current child of layout.
x	X position to move to.
y	Y position to move to.

Glib::PropertyProxy_ReadOnly<guint> Gtk::Layout::property_height

(

)

const

The height of the layout.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:

A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy<guint> Gtk::Layout::property_height

(

)

The height of the layout.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:

A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly<guint> Gtk::Layout::property_width

(

)

const

The width of the layout.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:

A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy<guint> Gtk::Layout::property_width

(

)

The width of the layout.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:

A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

void Gtk::Layout::put	(	Widget&	child_widget,
		int	x,
		int	y
	)

Adds child_widget to layout, at position ( x, y).

layout becomes the new parent container of child_widget.

Parameters:

child_widget	Child widget.
x	X position of child widget.
y	Y position of child widget.

void Gtk::Layout::set_size	(	guint	width,
		guint	height
	)

Sets the size of the scrollable area of the layout.

Parameters:

width	Width of entire scrollable area.
height	Height of entire scrollable area.
