I'm drawing a NSTextView and an NSImage to an NSView and doing some
animation with them. The NSTextView works fine, but I have a problem
with the NSImage.
I'm drawing the NSImage using -compositeToPoint:operation:, and I'm
painting out the background using [NSBeizerPath fillRect] just before
drawing the NSImage.
The problem is that the image flickers. Using Quartz Debug I can see
that the whole display is being painted black and then the image is
painted on top, but I want to stop the display until the image is drawn
in place.
Is this possible? I can't find it in the documentation, or in the
archives.
