glib will use the correct marshaller automatically. And as a side effect, we also get all glib optimizations, like a va marshaller.

/**

||
* 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-------------------->
