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]];
}
}
}
