I see. I've been having trouble forcing an NSTextField to get focus in document-modal sheets, and I wondered whether NSPanel/NSWindow should make a difference. (Experimentally it does not.)
I found on Snow Leopard that the following always worked: [sheetController window]; // load the NIB [sheet performSelector:@selector(makeFirstResponder:) withObject:myTextField afterDelay:0.]; [NSApp beginSheet:sheet modalForWindow:docWindow ... On Lion, it works for some sheets, but not others (very reproducible for any given sheet). Sometimes if the performSelector delay is > 0.8 sec, it works, but not always. The problem cases are always with NSTextField or its subclasses inside of NSTabViews. I also tried setting the sheet's initial first responder to be the text field and then calling: [sheet makeFirstResponder:sheet]; [sheet performSelector:@selector(selectNextKeyView:) withObject:nil afterDelay:0.]; That also works in some cases and not others on Lion. Am I trying the right things here? On 2012-02-02, at 7:10 PM, Graham Cox wrote: > NSPanel inherits NSWindow.
