Hi,
   Is there a way to specify a chunk of code to be executed when 
a TCanvas (or GUI window) is closed? Is it possible to do this under 
interpretted code without blocking without polling -- something akin to 
TPad::AddExec(char*, char*)?
   Does the number returned by TCanvas::GetCanvasID() have any utitility 
if the TCanvas is not embedded?
   Thank you.

David
