[pygtk] Drawing and signals

[Jeenu V]

Hi,

I wish to create an app which draws certain layout (like a graph,
mostly consisting of colored rectangles, and some labels) on to a
window after reading data from an external source. Additionally, I'd
like various parts of the layout receive signals (like click, hover
etc.) so that I can process the event and display details (in forms of
tool tip or pop-ups). First of all, I'd like to know if this is
possible with PyGTK; if so please suggest what widget(s) would fit
best.

Thanks
Jeenu
