virtual Gdk::DisplayManager::~DisplayManager ( ) [virtual]

Member Function Documentation

Gets the singleton Gdk::DisplayManager object.

When called for the first time, this function consults the <envar>GDK_BACKEND</envar> environment variable to find out which of the supported GDK backends to use (in case GDK has been compiled with multiple backends).

Since gtkmm 2.2:
Returns:
The global Gdk::DisplayManager singleton; gdk_parse_args(), gdk_init(), or gdk_init_check() must have been called first.

Gets the default Gdk::Display.

Since gtkmm 2.2:
Returns:
A Gdk::Display, or 0 if there is no default display.

Gets the default Gdk::Display.

Returns:
A Gdk::Display, or 0 if there is no default display.
GdkDisplayManager* Gdk::DisplayManager::gobj ( ) [inline]

Provides access to the underlying C GObject.

Reimplemented from Glib::ObjectBase.

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

List all currently open displays.

Since gtkmm 2.2:
Returns:
A list of Gdk::Display objects.

Opens a display.

Since gtkmm 3.0:
Parameters:
nameThe name of the display to open.
Returns:
A Gdk::Display, or 0 if the display could not be opened.

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.

The default display for GDK.
