I have a dialog window that can be cancelled through a custom Cancel button or using the system red window button. I need to perform some simple logic when the dialog is cancelled. How do I detect that the user has pressed the red button?
I know I can detect the window being closed using the -windowWillClose:
delegate callback. But this callback is also called when I close the window programmatically after the dialog succeeds. I also know I could simply set up a BOOL
flag, but is there a better solution? It would be best if I could detect the red button activation.
