I have an NSTableView which has its background set to be semi transparent in IB. When I add content to the table view, they appear to get drawn twice, giving a ‘boldface’ effect. If I select a row (or drag something over it) it reverts back to its normal, non-bolded self. How can I avoid these double-draws?
normal rendering, eg after selecting the rows
funky double rendering, eg after a new item has been added to the table
hmm…not sure how to do that. I tried [self setNeedsDisplayInRect:[aCell rect]]; - which gives me ‘selector not recognized’ errors
in the controller
“Only Views responds to setNeedsDisplayInRect:; you should send that message to the NSTableView instance, once for every cell needing to be redrawn.”
at what stage would I call this? I have tried at willDisplayCell:
