a question about using gtkHandleBox

[Guofu Chen <itcecsa gmail com>]

does anyone know the behavior of gtkHandleBox? I want to find the following
functionality for it:


1. trigger a callback while hovering mouse over the handle. basically i want
to emit a signal while hovering the mouse(which is not a image of pointer at
this moment) over widgets on other gtkHandleBox.

2. able to dock it on different position of the container. i have multiple
gtkHandleBox on container, and I want to sometimes change the relative
position of each gtkHandleBox, can I actually do it on the UI. if possible,
what are the solution?


thanks!
