    1. COIt sound right that this is a priority issue. However, in the case that prompted this posting, the window was larger than what the added subview needed. The subview wouldn't have been compressed, but instead expanded (the problem was that it didn't expand but instead the window shrunk). Does this mean the compression resistance priority wouldn't come into play? Must the Content Hugging priority instead also be set to <500, or am I confused? (I've been working with auto-layout for almost a year and I still find it difficult to visualize the purpose of those 2 sets of priorities).

    2. COAnswering my own question in the above comment: I had to make my view set needsDisplay to YES whenever its frame changed, and I overrode setFrame itself to do it. I'm not sure if this is the normal way to do this, or if there's some built-in mechanism similar to CALayer's needsDisplayOnBoundsChange, but its working.

    3. COYou're both finding scaling the documentView's superview to scale perfectly? I'm seeing clipping on the right & incorrect reflow. Are you scaling just once, or repeatedly, as in zoom in & out buttons under user control? scaleUnitSquareToSize doesn't work as one might expect in this circumstance, I finally found this Apple Q&A which shed some light https://developer.apple.com/library/mac/#qa/qa2004/qa1346.html but something still isn't right. Using the category there, I'm using essentially: clipView=[documentView superview]; clipView.scale=NSMakeSize(scale,scale); clipView.needsDisplay=YES;

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
