Re: ? re: Win32lib an onClick (+fan mail)
Hi Sherm,
I guess there must be some reason this won't work, or someone would have
suggested it, but here's what I would have tried:
Make an integer variable to serve as a true/false flag,
("Flag_StopDisplay"), & initialize it to 0; make a procedure to respond to
the "stop" button click event that sets the flag to 1; put a test for that
flag in your while loop, with "exit" if the flag = 1 (with reset the flag to
0 before the exit command).
I guess it wouldn't stop your BMP display in the middle of putting up a
specific picture, but I would think it would stop at the beginning or end of
one, and they're small enough that that might be serviceable??
