Simple. Start a timer on mouse down, invalidate it on mouse up.
Something like this (written in mail):
NSTimer *timer;
-(void)mouseDown:(NSEvent*)ev
{
timer=[[[NSTimer alloc] blah ...] retain];
}
-(void)mouseUp:(NSEvent*)ev
{
if ( [timer isValid] ) {
[timer invalidate];
[timer release];
timer = nil;
} else {
// perform single-click action
}
}
-(void)performHoldAction:(NSTimer*)tmr
{
// pop up menu
}
