- * SECTION:gtkhandlebox
- * @Short_description: a widget for detachable window portions
- * @Title: GtkHandleBox
- *
- * The #GtkHandleBox 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.
- *
- * > #GtkHandleBox 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.

-/* The algorithm for docking and redocking implemented here
- * has a couple of nice properties:
- *
- * 1) During a single drag, docking always occurs at the
- * the same cursor position. This means that the users
- * motions are reversible, and that you won't
- * undock/dock oscillations.
- *
- * 2) Docking generally occurs at user-visible features.
- * The user, once they figure out to redock, will
- * have useful information about doing it again in
- * the future.
- *
- * Please try to preserve these properties if you
- * change the algorithm. (And the current algorithm
- * is far from ideal). Briefly, the current algorithm
- * for deciding whether the handlebox is docked or not:
- *
- * 1) The decision is done by comparing two rectangles - the
- * allocation if the widget at the start of the drag,
- * and the boundary of hb->bin_window at the start of
- * of the drag offset by the distance that the cursor
- * has moved.
- *
- * 2) These rectangles must have one edge, the “snap_edge”
- * of the handlebox, aligned within TOLERANCE.
- *
- * 3) On the other dimension, the extents of one rectangle
- * must be contained in the extents of the other,
- * extended by tolerance. That is, either we can have:
- *
- * <-TOLERANCE-|--------bin_window--------------|-TOLERANCE->
- * <--------float_window-------------------->
- *
- * or we can have:
- *
- * <-TOLERANCE-|------float_window--------------|-TOLERANCE->
- * <--------bin_window-------------------->
