Hi, I've a subclass of NSTableView that draws a custom gradient background. What I'd like to do now is to draw a slightly different background when the window containing the custom NSTableView loses focus. Is this possible ? If so, could someone please point me in the right direction ? I know that in the NSTableView subclass you can use [self window] to get the containing window, so I have tried things like [[self window] isKeyWindow] and [[self window] isMainWindow] but this doesn't seem to get me anywhere.
In addition to what Nick said, you probably aren't invalidating the tableview when the window looses/gains key status.
What you want to do does work, and is possible; the NSTableViewSourceListHighlightStyle does this automatically.
