I would think that this code would work for your purposes:
id superview = startView;
while (superview)
{
if ([superview isKindOfClass:[NSTabView class]])
return [superview selectedTabViewItem];
superview = [superview superview];
}
return nil;
Presumably whichever NSTabViewItem the pane belongs to, is the currently
selected one in its NSTabView - otherwise how could the action be generated
from a non-visible view?
