I tried this, but performClose: was not called after I pressed the close (red) button. The intent of this method seems to be to simulate the click, not respond to it. > Otherwise, you can make your class implement the NSWindow delegate method > -windowShouldClose:, which will also be called when the user tries to close > the window. This method is called after I press the close (red) button. My only concern here is that the method does not necessarily lend itself to be exclusively called at this time and it would be a problem if it was ever called if the window was being closed for any other reason. So, how certain is it that it will _only_ be called if the user presses the close (red) button? With the old toolbox, one would receive a mouse down event and be able to determine what window and what part of the window it belonged to. One of these parts was "inGoAway". I just need the same information with the same reliability. Now, I suppose I could attach a carbon event handler to my window and ask for kEventClassWindow / kEventWindowClickCloseRgn events, but I was hoping to avoid this and am surprised that there isn't something as clear in Cocoa. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
