I have an NSView with two subviews (A & B) placed horizontally with respect to each other. The subviews can take a variable number of uniformly sized subviews. I’ve placed these constraints on subviews A & B, (all done in IB):
(They should both have the same height)
Top space to container
Bottom space to container
Horizontal spacing between A & B
Intrinsic View -> Placeholder -> Width checked to None
Horizontal content hugging priority set to 1
The left has:
Leading space to container
The right has:
Trailing space to container
The parent view has:
Intrinsic View -> Placeholder -> Width checked to None
Horizontal content hugging priority set to 1
With these constraints, I would expect the parent view to resize itself horizontally as the subviews (A & B) try to expand to accomodate the addition of more subviews. But instead, the parent view does not resize at all, subviews A & B do not resize and their subviews are crammed together as more are added. If I remove the Horizontal spacing between A & B, they both resize horizontally, and if I add enough subviews to each, they extend beyond the right edge of the parent view.
So, how what mojo do I need to apply to get the parent to resize horizontally?
I’m really just getting started with Auto layout, and it seems more confusing than it probably really is or should be.
Thanks
