    <p>I have an <code>NSView</code> with a custom subclass that draws a grid of rounded rectangles inside it. This <code>NSView</code> was placed with interface builder and on top of it I have some <code>NSButton</code>s. </p> <p>The problem is that sometimes when the view is re-drawn (ie, when i click a button on top of it) then it re-draws over some of the buttons that are meant to stay on top. When this happens only the smaller rounded rects appear over the buttons though, not the background one that is drawn before the loop.</p> <p>Here is the code form drawRect:</p> <pre><code>[NSGraphicsContext saveGraphicsState]; NSBezierPath *path = [NSBezierPath bezierPathWithRect:self.bounds]; [[NSColor grayColor] set]; [path fill]; [NSGraphicsContext restoreGraphicsState]; for( int r = 0; r &lt; 15; r++ ){ for( int c = 0; c &lt; 15; c++ ) { [NSGraphicsContext saveGraphicsState]; // Draw shape NSRect rect = NSMakeRect(20 * c, 20 * r, 15, 15); NSBezierPath *roundedRect = [NSBezierPath bezierPathWithRoundedRect: rect xRadius:1 yRadius:1]; [roundedRect setClip]; // Fill [[NSColor colorWithCalibratedHue:0 saturation:0 brightness:0.3 alpha:1] set]; [roundedRect fill]; // Stroke [[NSColor colorWithCalibratedHue:0 saturation:0 brightness:0.5 alpha:1] set]; [roundedRect setLineWidth:2.0]; [roundedRect stroke]; [NSGraphicsContext restoreGraphicsState]; } } </code></pre> <p>Here's a screenshot: <img src="https://i.stack.imgur.com/yvLgY.png" alt="Screenshot"></p> <p><strong>Update:</strong> Simplified the code, added a screenshot.</p>

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.
