    <p>This answer will be similar to my initial one, but updated for what, after more testing, works.</p> <p>So, first, my method of creating the italic font was deeply flawed. Instead of simply applying a rotation to the text, I needed to apply a skew transform. I ended up finding a good skew transform to apply at <a href="http://trac.webkit.org/browser/trunk/WebCore/platform/graphics/mac/FontMac.mm" rel="nofollow noreferrer">WebKit's Font code</a>. It contained the skew transform:</p> <pre><code>CGAffineTransformMake(1, 0, -tanf(SYNTHETIC_OBLIQUE_ANGLE * acosf(0) / 90), 1, 0, 0) </code></pre> <p>It does look good. </p> <p>Simply using a different font is not the correct answer. While the Lucida Sans font is virtually identical to Lucida Grande (which is returned by systemFontOfSize) and has a real italic variant, the italic variant will not draw Japanese Characters in italic. </p> <p>So, what appears to be the only answer is to obtain the systemFontOfSize, check to see if it has an italic variant, and, if not, add a skew transform.</p> <p>Here is my final solution:</p> <pre><code>NSFont *theFont = [NSFont systemFontOfSize:[NSFont systemFontSizeForControlSize:NSMiniControlSize]]; NSFontManager *sharedFontManager = [NSFontManager sharedFontManager]; if ( wantItalic ) { theFont = [sharedFontManager convertFont:theFont toHaveTrait:NSItalicFontMask]; NSFontTraitMask fontTraits = [sharedFontManager traitsOfFont:theFont]; if ( !( (fontTraits &amp; NSItalicFontMask) == NSItalicFontMask ) ) { const CGFloat kRotationForItalicText = -14.0; NSAffineTransform *fontTransform = [NSAffineTransform transform]; [fontTransform scaleBy:[NSFont systemFontSizeForControlSize:NSMiniControlSize]]; NSAffineTransformStruct italicTransformData; italicTransformData.m11 = 1; italicTransformData.m12 = 0; italicTransformData.m21 = -tanf( kRotationForItalicText * acosf(0) / 90 ); italicTransformData.m22 = 1; italicTransformData.tX = 0; italicTransformData.tY = 0; NSAffineTransform *italicTransform = [NSAffineTransform transform]; [italicTransform setTransformStruct:italicTransformData]; [fontTransform appendTransform:italicTransform]; theFont = [NSFont fontWithDescriptor:[theFont fontDescriptor] textTransform:fontTransform]; } } </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.
