[gnome-love] Developing GNOME panel applet: some help

["Debarshi 'Rishi' Ray" <debarshi ray gmail com>]

I am developing a GNOME panel applet for GNOME 2.6 (I am stuck with 2.6
until Fedora Core 5 come out). I need to know how to trigger a callback
function when something (file, folder)  is dragged-and-dropped onto the
applet. Moreover how do I display a progressbar beside the applet icon?

Thanks in advance,
Debarshi
