GtkHandleBox
GtkHandleBox — a widget for detachable window portions
|
|
Implemented Interfaces
GtkHandleBox implements
AtkImplementorIface and GtkBuildable.
Includes
#include <gtk/gtk.h>
Description
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.

GtkPositionType edge);
gtk_handle_box_set_snap_edge has been deprecated since version 3.4 and should not be used in newly-written code.
GtkHandleBox has been deprecated.
Sets the snap edge of a handlebox. The snap edge is
the edge of the detached child that must be aligned
with the corresponding edge of the “ghost” left
behind when the child was detached to reattach
the torn-off window. Usually, the snap edge should
be chosen so that it stays in the same place on
the screen when the handlebox is torn off.
If the snap edge is not set, then an appropriate value
will be guessed from the handle position. If the
handle position is GTK_POS_RIGHT or GTK_POS_LEFT,
then the snap edge will be GTK_POS_TOP, otherwise
it will be GTK_POS_LEFT.
