Detailed Description

The purpose of the GdkDisplayManager singleton object is to offer notification when displays appear or disappear or the default display changes.

virtual

Member Function Documentation

static Glib::RefPtr<DisplayManager> Gdk::DisplayManager::get ( )

static

Gets the singleton Gdk::DisplayManager object.

When called for the first time, this function consults the GDK_BACKEND environment variable to find out which of the supported GDK backends to use (in case GDK has been compiled with multiple backends). Applications can use gdk_set_allowed_backends() to limit what backends can be used.

Since gtkmm 2.2:

Returns

The global Gdk::DisplayManager singleton; gdk_parse_args(), gdk_init(), or gdk_init_check() must have been called first.

Glib::RefPtr<Display> Gdk::DisplayManager::get_default_display

(

)

Gets the default Gdk::Display.

Since gtkmm 2.2:

Returns

A Gdk::Display, or 0 if there is no default display.

Glib::RefPtr<const Display> Gdk::DisplayManager::get_default_display

(

)

const

Gets the default Gdk::Display.

Since gtkmm 2.2:

Returns

A Gdk::Display, or 0 if there is no default display.

static GType Gdk::DisplayManager::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

GdkDisplayManager* Gdk::DisplayManager::gobj ( )

inline

Provides access to the underlying C GObject.

const GdkDisplayManager* Gdk::DisplayManager::gobj ( ) const

inline

Provides access to the underlying C GObject.

GdkDisplayManager* Gdk::DisplayManager::gobj_copy

(

)

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

std::vector< Glib::RefPtr<Display> > Gdk::DisplayManager::list_displays

(

)

List all currently open displays.

Since gtkmm 2.2:

Returns

A list of Gdk::Display objects.

Glib::RefPtr<Display> Gdk::DisplayManager::open_display

(

const Glib::ustring &

name

)

Opens a display.

Since gtkmm 3.0:

Parameters

name	The name of the display to open.

Returns

A Gdk::Display, or 0 if the display could not be opened.

Glib::PropertyProxy< Glib::RefPtr<Display> > Gdk::DisplayManager::property_default_display

(

)

The default display for GDK.

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 value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< Glib::RefPtr<Display> > Gdk::DisplayManager::property_default_display

(

)

const

The default display for GDK.

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

Returns

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

void Gdk::DisplayManager::set_default_display

(

const Glib::RefPtr< Display >&

display

)

Sets display as the default display.

Since gtkmm 2.2:

Parameters

display

A Gdk::Display.

Glib::SignalProxy1< void,const Glib::RefPtr<Display>& > Gdk::DisplayManager::signal_display_opened

(

)

Slot Prototype:

void on_my_display_opened(const Glib::RefPtr<Display>& display)

The signal_display_opened() signal is emitted when a display is opened.

Since gtkmm 2.2:

Parameters

display

The opened display.

Friends And Related Function Documentation

Glib::RefPtr< Gdk::DisplayManager > wrap ( GdkDisplayManager *  object, bool  take_copy = false  )

related

A Glib::wrap() method for this object.

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns

A C++ instance that wraps this C instance.
