Not to worry, just realised what is happening. drawRect: gets called
for ALL drawing operations in the view, not just background as I
expected.
Carry on...

Hi everyone,
I have a Custom View in IB with an rounded NSTokenField (Focus ring
set to none) and a rounded rect NSButton embedded in it. In XCode I
have the Custom View class set to my subclass of NSView, with the
following code:
- (void)drawRect:(NSRect)rect {
NSGradient *gradient = nil;
NSBezierPath *path = [NSBezierPath bezierPathWithRect:rect];
[[NSColor blackColor] setFill];
[path fill];
// Create gloss gradient
gradient = [[NSGradient alloc] initWithStartingColor:[NSColor
colorWithCalibratedWhite:1.0 alpha:0.3]
endingColor:[NSColorcolorWithCalibratedWhite:1.0alpha:
0.2]];
// Make a half-height rectangle
rect = NSMakeRect(rect.origin.x, (rect.origin.y +
(rect.size.height)/2), rect.size.width, (rect.size.height)/2);
path = [NSBezierPath bezierPathWithRect:rect];
[gradient drawInBezierPath:path angle:-90];
// Create upper highlight
path = [NSBezierPath bezierPath];
[path moveToPoint:NSMakePoint(rect.origin.x, (rect.origin.y +
rect.size.height))];
[path lineToPoint:NSMakePoint(rect.size.width, (rect.origin.y +
rect.size.height))];
[path closePath];
[path setLineWidth:2];
[[NSColor colorWithCalibratedWhite:1.0 alpha:0.2] setStroke];
[path stroke];
}
The gradient draws as expected. The upper highlight also draws as
expected in the view, but also on the NSTokenView and NSButton,
which is unexpected and I don't know why this is so. Can anyone
offer any info as to why this is the case?
Regards,
JJ
