Hope you guys can help me with this one, I've tried just about everything. Here's what I'm trying to do:
- I have a frame with a panel
- The panel has a bunch of controls, including a textctrl object to capture "total time".
- The "total time" textctrl object has a custom text validator.
- There is a kill focus event handler on the text validator.
Here's the problem. Closing the application calls the event handler for the "total time" object and then closes the application. However, if I go to the task manager the "exe" is still running???
How do I prevent the event handler for "total time" from being called when the frame is closed? I'm using wxWindows 2.4.2 on Windows XP.
Thanks.
Ray
