Sounds very doubtful. [self controlView] is probably unreliable in your cell - you might want to check it. But even if it’s correct (being the NSMatrix for the browser column) invalidating the whole thing is going to be very sub-performant (though should work). Note that NSBrowser, unlike a NSTableView, allocates one cell per row within a NSMatrix - it does not reuse and redisplay a single cell. —Graham _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
