If all you want is a custom shape button, subclass NSButton and override a few
methods, -hitTest:.
http://developer.apple.com/documentation/Cocoa/Reference/ApplicationKit/Classes/NSView_Class/Reference/NSView.html#//apple_ref/occ/instm/NSView/hitTest:
Use whatever image you want. Then implement hitTest
Composed in mail:
- (BOOL)isOpaque
{
return NO;
}
- (BOOL)hitTest:(NSPoint)aPoint
{
BOOL result = [super hitTest:aPoint];
if(result)
{
NSPoint localPoint = [self convertPoint:aPoint fromView:[self superview]];
if(local point doesn't hit non-transparent color in my image)
{
result = NO;
}
}
return result;
}
