Thank you! As for field editor - can it appear and disappear during runtime? Indeed, I do not familiar with this approach.
About beginSheetModalForWindow - indeed, I tried to do the following either: [textField beginSheet:[textField window] ModalForWindow:[superView window] modalDelegate:superView didEndSelector:0 contextInfo:0]; and yes, I implemented endSheet. I tried to call endSheet from mouseDown event. I saw this function being called, however still, the white window was not closed and I was stuck in beginSheet (The code after it was unreachable).

If you aren't familiar with it, I'd advise taking some time to investigate it and see if you can adapt it to your needs. Even if not, the description of how it works (integration with responder chain, delegate methods) should prove useful. I would recommend it over the approach of trying to force application or window modal operation. > Here is the code. I do it not within the main view but from the side > function.

Given the code, it looks like you're trying to force the window with the text field into an application modal "mode".

So textField is an NSSavePanel or NSAlert? Those seem to be the only objects (other than more obscure objects like ABIdentityPicker) with beginSheetModalForWindow:modalDelegate:didEndSelector:contextInfo: methods. I'll assume you meant - [NSApplication beginSheet:modalForWindow:modalDelegate:didEndSelector:contextInfo:]. It requires an endSheet call (delegate method? notification?) to exit. In any case, I would not recommend this approach either. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
