Member Function Documentation

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

(

)

[static]

Gets the singleton Gdk::DisplayManager object.

Since gtkmm 2.2:

Returns:

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

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.

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.

const GdkDisplayManager* Gdk::DisplayManager::gobj

(

)

const [inline]

Provides access to the underlying C GObject.

Reimplemented from Glib::ObjectBase.

GdkDisplayManager* Gdk::DisplayManager::gobj

(

)

[inline]

Provides access to the underlying C GObject.

Reimplemented from Glib::ObjectBase.

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.

Glib::SListHandle< Glib::RefPtr<Display> > Gdk::DisplayManager::list_displays

(

)

List all currently open displays.

Since gtkmm 2.2:

Returns:

A list of Gdk::Display objects.

virtual void Gdk::DisplayManager::on_display_opened

(

const Glib::RefPtr< Display >&

display

)

[protected, virtual]

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

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 property of the value, 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

(

)

The display_opened signal is emitted when a display is opened.

Since gtkmm 2.2:

Parameters:

display

the opened display

Prototype:

void on_my_display_opened(const Glib::RefPtr<Display>& 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.
