Problem with Auto Layout and drawRect

[Dave]

Hi,

I have a View subclass called LTWDrawFrameView that has been working since the 
dawn of time and would like to make it work with auto layout. 

All it does it optionally Draw a Frame Around an NSView and/or fill the view 
with a solid color. 

On the face of it, I can’t see the need to do anything special for auto layout 
in this subclass, but when I add this to an NSScrollView and NSStackView combo 
(see other thread), I get some lines are drawn where they shouldn’t be 
seemingly at random.

translatesAutoresizingMaskIntoConstraints is set to no for these views.

I’ve pasted the class below, can anyone see anything wrong with it in terms of 
not working in a Scroll/Stack View and auto layout?

Thanks a lot
Dave
