I'm doing this:
- (void)mouseMoved:(NSEvent *)theEvent {
NSPoint where = [theEvent locationInWindow];
where = [self convertPoint:where fromView:nil]; // Convert to the
view's frame of reference
NSLog(@"Mouse Y: %3.0f", where.y);
}
And the results are as described previously. This is the means that Apple
docs said to use to convert the window coordinates to view coordinates...
am I missing something?
