Hi Again Lee Ann,
Thanks a lot for this, one thing though, how do I tell which window the position is in? At present I loop through all my open windows and apply run “hitTest” on the content view until I find one.
> Another thing you've missed: converting to myContentView's coordinate space from the window's space, with [myContentView convertPoint:myWindowPoint fromView:nil] - "If aView is nil, this method instead converts from window base coordinates"
Do I have to worry about this? It seems to work, but the window I am testing in is a plain (no title bar etc) window, so the content view and the window Frame coincide, do I need to add this for safety in case the window does have a title bar?
Here is the code I am using, it seems for work ok:
myContentView = self.window.contentView;
myGlobalPoint.x = theGlobalPoint.x;
myGlobalPoint.y = NSMaxY([[[NSScreen screens] objectAtIndex:0] frame]) - theGlobalPoint.y; //Flip
myWorkRect.origin = myGlobalPoint;
myWorkRect.size = NSMakeSize(1,1);
myWorkRect = [self.window convertRectFromScreen:myWorkRect];
myWindowPoint = myWorkRect.origin;
myCocoaControlView = (LTWViewBase*) [myContentView hitTest:myWindowPoint];
if (myCocoaControlView != nil)
{
if ([myCocoaControlView class] == [myContentView class])
myCocoaControlView = nil;
else if ([[myCocoaControlView class] isSubclassOfClass:[LTWViewBase class]] == NO)
myCocoaControlView = nil;
}
All the Best
Dave
