Widget for detachable window portions.
None.
GtkHandleBox allows for widgets to be "torn out" of a window and to become their own floating window. The GtkHandleBox displays its child along with a handle that the user can drag to tear the widget out of its containing window and into its own float window. When the widget is torn out of the original window, its place is held by a thin ghost widget. By draging the float window back to the ghost widget and aligning the snap edge, the float window can be reattached.
GtkHandleBox is a decendant of GtkBin, which means that it may container only one child. If you would like to have more than one widget in the same float window, you must first add those widgets to a container capable of holding more than one child, such as a GtkVBox.
