Those times I checked, it was the panel itself that was the first responder.
BUT, in the meantime, I decided to retry another route that I had been
experimenting with the last couple of days, and I have now found a working
solution, although maybe a little complicated.
It involves 'listening' for the mouseDown: event that is sent to the
NSThemeFrame object when you click the panel's titlebar. I'm using the panel's
'awakeFromNib' to replace the default NSThemeFrame' mouseDown: method with my
own implementation which allows the panel to become key (setting a BOOL
property), and then I send the panel a 'makeKeyWindow:' message. Second, I'm
using the window delegate to reset the ability of the panel to become key in
'windowDidResignKey:'.
So once I click out of the panel, its ability to become key is switched back
off again and things are back to their initial state.
I still am going to have to optimise this a little bit in the next few days.
Anyway, thanks for all the help and advice.
