Well, there is no flicker issue to worry about, but to optimise for this case (i.e. save some CPU cycles), have the view you are drawing into return YES from its isOpaque method. Cocoa will then assume that this view completely obliterates whatever lies behind it (including the content view). You could also subclass the content view if you want to (you can do this in Interface Builder) and draw directly into that.

I don't see an override on background drawing so I was wanting to eliminate the backgroud of the content view. _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
