Description |
Add a handle to some other widget so that it can be detached and
reattached from the main application.
- 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 explicitely, 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 PosBottom.

handleBoxSetSnapEdge :: HandleBoxClass hb => hb -> PositionType -> IO () |

- 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
PosRight or PosLeft, then the snap edge will
be PosTop, otherwise it will be PosLeft.
