My app has floating palettes that generally set [NSPanel
setBecomesKeyOnlyIfNeeded:YES]; Most of the time these palettes are therefore
inactive, and yet provide a large number of useful controls that work as
expected when operated. Problem is, a lot of these controls show the inactive
state because the window is inactive. (This isn't actually very consistent, it
depends on the control style chosen).
In the past, I have used a hack to fool controls into thinking they were in a
window that was active when it actually wasn't, by subclassing NSPanel and
overriding:
- (BOOL) _hasActiveControls
{
return YES;
}
This no longer seems to work since some versions ago, as well as being
undocumented, and inapplicable for the App Store and so on.
I'd like to know if there is a supported way to do this. It seems a bit crazy
that floating panels even bother modulating the active state of controls when
they are floating and are *always* effectively active, and it looks better and
is more usable as well.
