Well, you can check the current position of cursor. Do you know
positions of your surfaces (widgets)?
There is the helpful macros DFB_RECTANGLE_CONTAINS_POINT() for these cases.
And I advice you to use for your widgets only subsurfaces of the
primary surface. The DSCAPS_SUBSURFACE flag.
Secondly, perhaps you should use one of widget libraries to develop UI
without troubles.
For instance, LiTE (http://www.directfb.org/index.php?path=Platform%2FLiTE)
Or my port of FLTK ;-) (main site http://fltk.org)
