    <p><a href="http://code.google.com/p/whirlyglobe/" rel="nofollow">WhirlyGlobe</a> is a very useful framework and I would like to display Country Flags instead of names for each countries. When looking at LabelLayer.h it seems possible to overwrite the icontexture generated from Text label by a picture:</p> <pre><code>@interface SingleLabel : NSObject { NSString *text; WhirlyGlobe::GeoCoord loc; NSDictionary *desc; // If set, this overrides the top level description WhirlyGlobe::SimpleIdentity iconTexture; // If non-zero, this is the texture to use as an icon } </code></pre> <p>But I didn't find any way to use label for picture display.<br> Can someone please help me understand how to replace Text label by Picture label? </p> <p>Following @Mousebird first answer here is what I"ve implemented:</p> <pre><code>// This describes how our labels will look NSDictionary *labelDesc = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:YES],@"enable", [UIColor clearColor],@"backgroundColor", [UIColor whiteColor],@"textColor", [UIFont boldSystemFontOfSize:16.0],@"font", [NSNumber numberWithInt:4],@"drawOffset", [NSNumber numberWithFloat:0.08],@"height", [NSNumber numberWithFloat:0.08],@"width", nil]; // Build up an individual label NSMutableArray *labels = [[[NSMutableArray alloc] init] autorelease]; SingleLabel *texLabel = [[[SingleLabel alloc] init] autorelease]; Texture *theTex = new Texture(@"icon", @"png"); theTex-&gt;setUsesMipmaps(true); texLabel.text = @""; texLabel.iconTexture = theTex-&gt;getId(); theScene-&gt;addChangeRequest(new AddTextureReq(theTex)); [texLabel setLoc:GeoCoord::CoordFromDegrees(5, -3)]; [labels addObject:texLabel]; [self.labelLayer addLabels:labels desc:labelDesc]; </code></pre> <p>Still a problem, the texture is loaded in memory but didn't appear. Putting a string as a text create a Blank square on the first character of the label </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.
