Peter, I've run into something similar and I think it has to do with
the window server not making a window active (i.e. main and key) if it
has the borderless attribute. The workaround I ended up using was to
override a private undocumented NSWindow method which controls use to
query the active state of the window, to always return YES.
Unfortunately I've dug through a mountain of code but can't find where
I used it. Someone else may remember this trick and help me out... of
course, it's not a great solution but it works from 10.3 through 10.5
so far...

When I add an NSTextField to a borderless window, nothing I do will
make it editable. Specifically, running the code below, the text
field just won't work. (I've tried it with all backing types, BTW.)
NSWindow *window = [[NSWindow alloc]
initWithContentRect:NSMakeRect(300,300,300,300)
styleMask:NSBorderlessWindowMask backing:NSBackingStoreBuffered
defer:NO];
NSTextField *field = [[NSTextField alloc] init];
[field setEditable:YES];
[window setContentView:field];
[window makeKeyAndOrderFront:self];
But change the styleMask to NSTitledWindowMask and it works as
expected.
What am I missing? Is it impossible to do this for some reason? On
the subject of NSBorderlessWindowMask, the docs give the rather
opaque guidance, "Useful only for display or caching purposes," as
if a window was useful for anything other than display. Is there
some other, better way to create a completely custom window?
I'm running 10.5.2, if that matters.
Thanks,
Peter Burtis
