Re: Drawing from secondary thread erases resize corner in window? [solved, for now]

the only reason I'm trying to draw on another thread is that my drawing is timer-driven, and the timer gets suspended if it's on the main thread and the user clicks on a menu or a scrollbar or some such thing. You could also use [[NSRunLoop mainRunLoop] addTimer:yourTimer forMode:NSEventTracki

Re: Drawing from secondary thread erases resize corner in window? [solved, for now]

I haven't found out what I need to do to avoid drawing over the resize corner on a secondary thread. There's something that the system does when it calls drawRect: as a result of a call to setNeedsDisplayInRect: that I can't reproduce. I'm pretty sure it's not a multithreading issue, but si

Drawing from secondary thread erases resize corner in window?

Hi list, I have a window with a custom view that occupies the entire window, so the little resize corner in the lower right is within the bounds of the view. I noticed that when I draw into the window from the main thread (i.e. the usual way) that resize corner is redrawn when the view is
