    <p>Why would you expect it to send you delegate messages if you aren't (yet) its delegate? If you want it to send you delegate messages, then you need to set yourself as its delegate.</p> <blockquote> <p>I tried calling a <code>setDelegate</code>, but get warned about impending doom if I continue down that route...</p> <blockquote> <p>[QL] <code>QLError()</code>: <code>-[QLPreviewPanel setDelegate:]</code> called while the panel has no controller - Fix this or this will raise soon. See comments in QLPreviewPanel.h for <code>-acceptsPreviewPanelControl:</code>/<code>-beginPreviewPanelControl:</code>/<code>-endPreviewPanelControl:</code>.</p> </blockquote> </blockquote> <p>“No controller”, it says. So, you need it to have a controller.</p> <p>The comments on that header, particularly on <code>acceptsPreviewPanelControl:</code> and the QLPreviewPanel instance method <code>updateController</code>, suggest that the panel's controller, when it has one, is an object that is in the responder chain. Therefore, if your controller is not becoming the panel's controller, it's because your controller isn't in the responder chain.</p> <p>So, fix that, and then it'll work.</p> <p>I would imagine that your view controller should be in the responder chain whenever its view or any subview thereof is in the responder chain, but maybe this isn't the case. <a href="http://developer.apple.com/mac/library/documentation/Cocoa/Reference/NSViewController_Class/" rel="noreferrer">The documentation</a> doesn't say. If all else fails, set yourself as some view's next responder explicitly (and its previous next responder as your next responder), then send the preview panel an <code>updateController</code> message.</p>

    1. COAs usual Peter your observation was the error in my ways. I had overlooked the notion that the NSViewController needs adding into the responder chain (unlike a window controller which automatically get included). 3 lines of code and the problem is fixed automagically! Thanks. Late nights. You know how it goes :-)

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
