We have an HOWTO in preparation explaining this.To have a class member
function appearing as a ContextMenu item,
simply add teh following string in the comment field of thefunction
// *MENU*
See examples in header files of TCanvas, TPad, TAttLine,etc

> Yes, you can do it with a TControlBar, but I suggest you use the class
TButton instead.As I already mentionned several times to this list, we
will make available
at the end of this month a real example developped in collaboration
with ATLAS illustrating all the facets of Root and in particular
how to make an event display.
