Description:

[ Version ( deprecated = true , deprecated_since = "3.4" ) ]
public class HandleBox : Bin, Implementor, Buildable

Warning: HandleBox is deprecated since "3.4".

The HandleBox widget allows a portion of a window to be "torn off".

It is a bin widget which displays its child and a handle that the user can drag to tear off a separate window (the “float window”) containing the child widget. A thin “ghost” is drawn in the original location of the handlebox. By dragging the separate window back to its original location, it can be reattached.

When reattaching, the ghost and float window, must be aligned along one of the edges, the “snap edge”. This either can be specified by the application programmer explicitly, or GTK+ will pick a reasonable default based on the handle position.

To make detaching and reattaching the handlebox as minimally confusing as possible to the user, it is important to set the snap edge so that the snap edge does not move when the handlebox is deattached. For instance, if the handlebox is packed at the bottom of a VBox, then when the handlebox is detached, the bottom edge of the handlebox's allocation will remain fixed as the height of the handlebox shrinks, so the snap edge should be set to gtk_pos_bottom.

Note:

HandleBox has been deprecated. It is very specialized, lacks features to make it useful and most importantly does not fit well into modern application design. Do not use it. There is no replacement.
