Hello all:

Sorry about the previous message -- I had meant to cancel it and ended up
sending it instead.

My question was:

If, within a program, I create a TCanvas object and retain a pointer to
it, and then the user closes canvas window, what is the best way for the
program to examine the pointer and find out that the canvas has been closed?

Thanks,
