    <p>I have a Cocoa project using Autolayout, and I want to put a button (actually an <code>NSPathControl</code>) over a <code>NSScrollView</code> so that it stays in the same place on the screen even when the scrollView is scrolled.</p> <p>Whenever I add the button to the scrollView's parent, it ends up behind the scrollView (even if I explicitly use <code>addSubview:positioned:relativeTo:</code>. How do I get it to float above the scrollView?</p> <p>My fallback is to put it inside of the scrollView, turn on <code>translatesAutoresizingMaskIntoConstraints</code> and update the frame as the scrollView is scrolled. I would strongly prefer to use autolayout if possible though...</p> <p>Edit: Here is the layout code for the button (the layout for content in the scrollView is quite complex):</p> <pre><code>NSButton *button = [[NSButton alloc]initWithFrame:NSZeroRect]; button.translatesAutoresizingMaskIntoConstraints = NO; button.wantsLayer = YES;//Added incase this affects ordering (it doesn't seem to make a difference) [self.superview addSubview:button positioned:NSWindowAbove relativeTo:self]; [self.superview addConstraint:[NSLayoutConstraint constraintWithItem:button attribute:NSLayoutAttributeLeft relatedBy:NSLayoutRelationEqual toItem:self attribute:NSLayoutAttributeLeft multiplier:1.0 constant:20]]; [self.superview addConstraint:[NSLayoutConstraint constraintWithItem:button attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:self attribute:NSLayoutAttributeTop multiplier:1.0 constant:20]]; </code></pre>

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.
