Gary -- thanks --

Yes — your suggestion DOES set the minimum and maximum size for the user pane.   I confirmed by calling HIViewGetSizeConstraints().

HOWEVER — the HiView layout engine doesn’t seem to respect those sizes.  For example, when resizing the parent view the HIAxisScale I set works perfectly, scaling the size of the User Pane (and embedded panes).  But the user pane size is still allowed to drop below the minimum size, as well as grow above the maximum size.

The kEventControlGetSizeConstraints event is sent exactly once.  I assume that’s correct — the layout engine doesn’t request the size constraints while the window is resizing, correct?

Is there a user pane flag that must be supported?  Or possibly another event?
