<br>In Kori's reply to this post, he/she lists a set of commands based on the<br>widget javascript.<br>One of the commands is:<br><br>Fusion.getWidgetById('Legend').renderer.expandBranch(folder);<br><br>Unfortunately I need a little more context to this code.<br>
In particular, I need to know how the folder is derrived.<br>Some sample code would be appreciated! Or please direct me to a sample<br>website.<br><br>Question 2:<br>Also in regards to the OSGeo.MapGuide.MgLayerGroup property 'ExpandInLegend'<br>
- why does this only have a get and no set? 'DisplayInLegend' has a set and<br>a get. It would have been really convenient to just use this<br>'ExpandInLegend' property. Is there a way I can change this to it has a set?<br>
I have attached a screen shot of this property.<br><a href="http://osgeo-org.1803224.n2.nabble.com/file/n5648915/ExpandInLegend.png" target="_blank">http://osgeo-org.1803224.n2.nabble.com/file/n5648915/ExpandInLegend.png</a><br>
