    <blockquote> <p>"I read on some threads that using subclasses were advantageous..."</p> </blockquote> <p>Using subclasses may be advantageous but that's not what you are doing here.</p> <p>What you have done is implemented an <code>(SDLApplication)</code> <a href="http://developer.apple.com/library/mac/documentation/cocoa/conceptual/ProgrammingWithObjectiveC/CustomizingExistingClasses/CustomizingExistingClasses.html#//apple_ref/doc/uid/TP40011210-CH6-SW2">Objective-C Category</a> on <code>NSApplication</code>. In that category, you are overriding <code>NSApplication</code>'s <code>terminate:</code> method. In general, you should use categories only to add additional methods to an existing class, not to override existing methods, as that can have unpredictable results.</p> <p>What you really should do is subclass <code>NSApplication</code> so that you can override <code>terminate:</code> properly:</p> <pre><code>@interface SDLApplication : NSApplication { } @end @implementation - (void)terminate:(id)sender { SDL_Event event; event.type = SDL_QUIT; SDL_PushEvent(&amp;event); [super terminate:sender]; // this line is the key to assuring proper behavior } @end </code></pre> <p>The last step in your overridden <code>terminate:</code> method should be a call to <code>super</code>, so that the terminate method works as it should. (Using the keyword <code>super</code> in a category is not allowed; only the word <code>self</code>, which is why there's a need for subclassing).</p> <p>Make sure you also change the value for the <code>NSPrincipalClass</code> key in your <code>Info.plist</code> file to be <code>SDLApplication</code> instead of <code>NSApplication</code>.</p>

    1. COSo, what I said with code examples... Nice. </sarcasm>

    2. COYes i know my original code isn't using subclasses. I merely read somewhere that it was an alternative option to merely suppressing the warnings using `pragma`s. Having said that, i wasn't 100% sure how to implement a subclass in `C++` and this has been very helpful indeed :) Thanks for taking the time to explain this.

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).
