In my app I've got a secondary NSWindow that's created from .xib in my NSWindowController in my initWithWindowNibName: method. The window is a plain NSWindow with the title bar switched off.
After creating the window it's shown using makeKeyAndOrderFront: -
and all controls are disabled (text field, combo box).
I have (more than..) triple checked all flags in the window and the view hierarchy of the controls: everything is enabled, allowing editing and not refusing to be first responder.
Totally clueless. Any ideas?
Update #1:
I appears the problem is related to the window not having a title bar. When the title bar is switched on the window - and the controls in the window - behave as expected.
As pointed out by Ken the framework will automatically refuse becoming a key window if the window title is switched off:
Attempts to make the window the key window are abandoned if this method returns NO. The NSWindow implementation returns YES if the window has a title bar or a resize bar, or NO otherwise.
A simple subclass did the trick.
