Body
The simplest solution would just be to stroke the path twice. First with black at a bigger stroke width and then stroke the same path again using the blue color with a slightly smaller stroke width. Edit: If I remember correctly you can use <code>CGPathCreateCopyByStrokingPath(...)</code> to create a new path that you then can both stroke and fill. Then you could use semi-transparent colors. From the documentation: <blockquote> <h2><code>CGPathCreateCopyByStrokingPath</code> </h2> Creates a stroked copy of another path. <pre><code>CGPathRef CGPathCreateCopyByStrokingPath( CGPathRef path, const CGAffineTransform *transform, CGFloat lineWidth, CGLineCap lineCap, CGLineJoin lineJoin, CGFloat miterLimit ); </code></pre> Parameters path <code></code>The path to copy. transform <code></code>A pointer to an affine transformation matrix, or NULL if no transformation is needed. If specified, Quartz applies the transformation to elements of the converted path before adding them to the new path. lineWidth <code></code>The line width to use, in user space units. The value must be greater than 0. lineCap <code></code>A line cap style constant—kCGLineCapButt (the default), kCGLineCapRound, or kCGLineCapSquare. See “CGLineCap”. lineJoin <code></code>A line join value—kCGLineJoinMiter (the default), kCGLineJoinRound, or kCGLineJoinBevel. See “CGLineJoin”. miterLimit <code></code>The miter limit to use. </blockquote>

1. COI want the middle color to be simi-transparent though. Adding a black larger line behind it would make that impossible.

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.
