Description
The
Gtk_Handle_Box 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 explicitely, or GtkAda 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 detached. 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
Pos_Bottom.
