Hi Fred,
in the meanwhile I was able to test the
- (void)mouseDown:(NSEvent *)theEvent
{
NSLog(@"mouseDown ...");
[NSApp preventWindowOrdering];
[self highlight:YES];
NSEvent *mouseUpEvent = [[self window] nextEventMatchingMask:NSLeftMouseUpMask
untilDate:[NSDate distantFuture] inMode:NSEventTrackingRunLoopMode dequeue:YES];
NSPoint mouseLocation = [self convertPoint:[mouseUpEvent locationInWindow]
fromView:nil];
BOOL mouseUpInside = [self mouse:mouseLocation inRect:[self bounds]];
if (mouseUpInside)
{
if ([self target]) [[self target] performSelector:[self action]
withObject:self];
}
[self highlight:NO];
}
code fragment (NSButton subclass) on GNUstep. And as expected it does not work
there. So I am still looking for a solution ...
Do you know which part in the GNustep source tree resigns fist responder from a
currently active control and transfers it to a clicked button? I got somehow
lost in the event handling code.
Thanks a lot,
Andreas
