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 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.
Returns a paintable that has the given intrinsic size and draws nothing.

gtk.widget_paintable.WidgetPaintable is a gdk.paintable.Paintable that displays the contents of a widget.
gtk.widget_paintable.WidgetPaintable will also take care of the widget not being in a state where it can be drawn (like when it isn't shown) and just draw nothing or where it does not have a size (like when it is hidden) and report no size in that case.
Of course, gtk.widget_paintable.WidgetPaintable allows you to monitor widgets for size changes by emitting the signal@Gdk.Paintable::invalidate-size signal whenever the size of the widget changes as well as for visual changes by emitting the signal@Gdk.Paintable::invalidate-contents signal whenever the widget changes.
You can use a gtk.widget_paintable.WidgetPaintable everywhere a gdk.paintable.Paintable is allowed, including using it on a gtk.picture.Picture (or one of its parents) that it was set on itself via gtk.picture.Picture.setPaintable. The paintable will take care of recursion when this happens. If you do this however, ensure that the property@Gtk.Picture:can-shrink property is set to true or you might end up with an infinitely growing widget.
