hi!
I have a hopefully easier question refering to the same problem (the
last mail was "keyview madness").
I searched in the achives of this list and found out, that NSView's
nextKeyView has no effect until the window's initialFirstResponder is
set.
I experimented a bit and can confirm this.
Now the question:
Somehow a next/previous valid keyView is found anyway (although if you
have NOT set the initialFirstResponder), because the key focus cycles
through the controls from the top left to the bottom right as you press
tab/shift-tab.
I wonder HOW this is done. I think NSView's nextValidKeyView and
previousValidKeyView are invoked anyhow, but how do they find their
previous/next views? Do they walk through all views and find the
nearest or so ?
The reason for asking that question is: I want to alter the default
behaviour (I want some controls appearing NOT in the key view loop,
although they might get firstResponder), even when I didn't set the
initialFirstResponder.
Any hints?
Thanx!!
Tobi
