performClose: on a borderless window?

Question

Is there a way to have the method performClose: working when i use NSBorderlessWindowMask? What method do i have to override ? (if its possible)

Answer 1

i have overridden some methods, and it works. All I want to know now is if i didn't take it from the bad approach :)

- (BOOL)validateMenuItem:(NSMenuItem *)menuItem
{
    return ([menuItem action] == @selector(performClose:) || [menuItem action] == @selector(performZoom:) || [menuItem action] == @selector(performMiniaturize:)) ? YES : [super validateMenuItem:menuItem];
}

- (BOOL)windowShouldClose:(id)sender
{
    return YES;
}

- (void)performClose:(id)sender
{
    if([[self delegate] respondsToSelector:@selector(windowShouldClose:)])
    {
        if(![[self delegate] windowShouldClose:self]) return;
    }
    else if([self respondsToSelector:@selector(windowShouldClose:)])
    {
        if(![self windowShouldClose:self]) return;
    }

    [self close];
}

- (void)performMiniaturize:(id)sender
{
    [self miniaturize:self];
}

- (void)performZoom:(id)sender
{
    [self zoom:self];
}
