Some additional information that I just discovered: when the window is
textured, it does not flicker at all, but if not textured, it flickers
noticeably.

I have a window, and get that window to resize according to the
various custom views I plop in the window. My purpose here is to
(somewhat) emulate the system preferences window that grows and
shrinks as necessary. The resizing works fine, but when I want to
animate the resizing, there is a lot of flickering in the window.
Here is the short bit of code:
[w setContentView:nil];
[w setFrame:windowFrame display:YES animate:YES];
[w setContentView:v];
... where "w" is an NSWindow, and "v" is an NSView. "windowFrame"
is the recalculated window size that fits the view. So far, I have
tried to solve the flickering by subclassing NSWindow and
implementing the following override:
- (NSTimeInterval)animationResizeTime:(NSRect)newFrame
{
return 1.0;
}
But while this does slow down the animation significantly, it simply
makes the flickering slower.
Is there a way to use setFrame:display:animate: so that the
background of the window does not flicker?
Thanks.
