Many thanks Patrick

All my sheets are sub-classes of an NSPanel that I call FastPanel - it returns 0.0 for animationResizeTime. So it is simple (but laborious) to plough through all my nib files sub-classing each ContentView to my equivalent of your PMPanelBackgroundView. We should not have to build this get around so I have submitted an enhancement request to Apple so that setAlphaValue sticks.

How do I override the Leopard defaults to display sheets with an alpha of 1.0?


My application uses a lot of NSWindow sheets - for a good reason.

I do NOT want a semi-transparent background, nor do my users.


Make the contentView of your window a custom view where you fill the rect with a solid colour. I actually used this to get rid of the pinstripes in Tiger, and it is not transparent in Leopard. I post the code down here, though that might be superfluous as it is really simple.


Cheers, Patrick
@interface PMPanelBackgroundView : NSView {
}
@end

#import "PMPanelBackgroundView.h"
@implementation PMPanelBackgroundView
- (void)drawRect:(NSRect)rect
{
	[[NSColor colorWithCalibratedWhite:0.9337 alpha:0.98] set];
	NSRectFill(rect);
}
@end
