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.

Hi Corbin,
I understand what Nick suggested and will look into it, but don't
quite understand what you mean by invalidating the tableview. Could
you give me a little more information ?
You will want to call [tableView setNeedsDisplay:YES] to get it to
redraw its custom background. You'll want to do this inside the
notifications for the window gaining/loosing key. That is all I meant.
