I have an app which overrides -[NSWindow miniaturize:] in a category (to avoid crowding the dock).Works perfectly, but...If this window being minimized has a sheet attached (attachedSheet is non-nil) this will be lost on deminiaturizing. But the modal loop is still running, waiting for some button to be pressed on the now invisible sheet.In this case Force Quit is the only way out. Not very nice. So, what can be done?1. On miniaturize simulate a click on the "Cancel" button of the sheet. But how?
If you have a reference to the cancel button, you can send the performClick:(id)sender message to it on miniaturize...
2. On deminiaturize reattach this sheet. But again: how?
In this case, when your miniaturization method is invoked, check to see if you are in the modal loop. If you are, abort the loop, set a state variable (probably some private ivar) and miniaturize. When you de-miniaturize, check the state var and if
set, display the sheet and start the modal loop again...
3. (don't like this very much) refuse to miniaturize if a sheet is open.
