I've got a window that is not opaque ( [self setOpaque: NO] ). It contains basically just one view.
I fill the view with a semi-transparent gray, like this:semiTransparentGray_ = [NSColor colorWithDeviceRed:0.1 green:0.1 blue: 0.1 alpha: 0.05];
[semiTransparentGray_ set]; NSRectFill( [self frame] );This makes the window receive all mouse events, which is exactly what I want.
The funny thing is: as soon as I set the alpha value to some value less than 0.05, the window does not receive the mouse events any more! I.e., it is click-through.
Can someone confirm that 0.05 is actually the minimum alpha value so that the window manager considers the window to be interested in the mouse events?
Or am I missing something? Thanks a lot in advance. Best regards, Gabriel. PS: For other reasons, the window must be non-opqaue.
