Connect to DisplayOpened signal.
Gets the default gdk.display.Display.
List all currently open displays.
Opens a display.
Sets display as the default display.
Gets the singleton gdk.display_manager.DisplayManager object.
Set the GObject of a D ObjectG wrapper.
Get a pointer to the underlying C object.
Calls g_object_ref() on a GObject.
Calls g_object_unref() on a GObject.
Get the GType of an object.
GObject GType property.
Convenience method to return this cast to a type. For use in D with statements.
Template to get the D object from a C GObject and cast it to the given D object type.
Connect a D closure to an object signal.
Template for setting a GObject property.
Template for getting a GObject property.
Creates a binding between source_property on source and target_property on target.
Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.
This function is intended for #GObject implementations to re-enforce a floating[floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling gobject.object.ObjectG.refSink.
Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.
Gets a named field from the objects table of associations (see gobject.object.ObjectG.setData).
Gets a property of an object.
This function gets back user data pointers stored via gobject.object.ObjectG.setQdata.
Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.
Checks whether object has a floating[floating-ref] reference.
Emits a "notify" signal for the property property_name on object.
Emits a "notify" signal for the property specified by pspec on object.
Increase the reference count of object, and possibly remove the floating[floating-ref] reference, if object has a floating reference.
Releases all references to other objects. This can be used to break reference cycles.
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
Sets a property on an object.
Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
This function gets back user data pointers stored via gobject.object.ObjectG.setQdata and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:
Reverts the effect of a previous call to gobject.object.ObjectG.freezeNotify. The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.
This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling gobject.closure.Closure.invalidate on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, gobject.object.ObjectG.ref_ and gobject.object.ObjectG.unref are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.
Connect to Notify signal.
A singleton object that offers notification when displays appear or disappear.
You can use gdk.display_manager.DisplayManager.get to obtain the gdk.display_manager.DisplayManager singleton, but that should be rarely necessary. Typically, initializing GTK opens a display that you can work with without ever accessing the gdk.display_manager.DisplayManager.
The GDK library can be built with support for multiple backends. The gdk.display_manager.DisplayManager object determines which backend is used at runtime.
In the rare case that you need to influence which of the backends is being used, you can use func@Gdk.set_allowed_backends. Note that you need to call this function before initializing GTK.
Backend-specific code
When writing backend-specific code that is supposed to work with multiple GDK backends, you have to consider both compile time and runtime. At compile time, use the GDK_WINDOWING_X11, GDK_WINDOWING_WIN32 macros, etc. to find out which backends are present in the GDK library you are building your application against. At runtime, use type-check macros like GDK_IS_X11_DISPLAY() to find out which backend is in use:
