Is there a simple way to get an NSScrollView to adapt to its document view changing size when using autolayout (the Lion feature)?
I have tried to call both setNeedsUpdateConstraints: and setNeedsLayout: on the document view, the clip view and the scroll view, without any results.
fittingSize of the document view reports the correct size.
An NSPopover in conjunction with an NSViewController handles this nicely, with the popover growing and shrinking as needed, and I was hoping to get a similar simple and robust behaviour with the scroll view. I have checked the documentation for scroll views, but they don't seem to be updated to use autolayout.
Edited to clarify:
The problem I experience is that the document view, which holds subviews, is not re-sized when the subviews change their size, even if they call invalidateIntrinsicContentSize. The contents of the document view are hence clipped to the original size of the document view as they grow. The document view is created in a nib and set as the scroll view's document view in an awakeFromBib method.
What I hoped to obtain was that the document view frame would automatically be adjusted to when its fittingSize changes, and the scrollbars updated accordingly.
NSPopover does something similar - provided that the subviews of the content controller's view have the constraints set right and various content hugging values are high enough (higher than the hidden popover window's hight constraint priority, for one).
