Hi, Let's keep the conversation on the mailing list :)
If GNUstep is tracking Cocoa, then this is the correct behavior. I didn't know about -fieldEditor:forObject: (thanks!) so I examined the first responder. For the sake of documentation, I'll post the code here. Again, it's for OS X but I suspect that it should work under GS, too. Providing a helper function that updates both the text field and the editor's background color might be an interesting GNUstep-specific extension to NSTextField class. [contactFirstNameTextField setBackgroundColor:[NSColor redColor]]; [contactLastNameTextField setBackgroundColor:[NSColor redColor]]; [contactCompanyTextField setBackgroundColor:[NSColor redColor]]; if ([self.window.firstResponder isKindOfClass:[NSText class]]) { NSText *textBox = (NSText*)self.window.firstResponder; /* for (NSResponder *parent = textBox.nextResponder; parent; parent = parent.nextResponder) { if(parent == contactFirstNameTextField || parent == contactLastNameTextField || parent == contactCompanyTextField) { if([textBox.nextResponder respondsToSelector:@selector (setBackgroundColor:)]) { [(id)textBox.nextResponder setBackgroundColor:[NSColor redColor]]; } break; } } */ NSTextField *parent = [textBox parentTextField]; if(parent == contactFirstNameTextField || parent == contactLastNameTextField || parent == contactCompanyTextField) { if([textBox.nextResponder respondsToSelector:@selector (setBackgroundColor:)]) { [(id)textBox.nextResponder setBackgroundColor:[NSColor controlBackgroundColor]]; } } } On Wed, Dec 7, 2011 at 06:11, Bluna Ratimonkey <obj...@gmail.com> wrote: > Hi, > A text field didn't generate a text view but invoke NSWindow's > -fieldEditor:forObject: which will return a shared among many > controls. > I already have a working code, the one I posted.
