[Users] How to turn on/off a radio button in a layer tree nodeprogrammatically?

[Valiquette,Francois [Montreal]]

Hello,

 

To check or uncheck the node “i” of your tree you can use something similar to this :

 

layerTreeRoot.childNodes[i].ui.toggleCheck(false)

or 

layerTreeRoot.childNodes[i].ui.toggleCheck(true)

 

And for the radio button I don’t know but I think it should be something similar.

 

Good luck

 

François

Hello everyone:

 

I am learning GeoExt and trying the example "Tree Node", the url of the example is "http://api.geoext.org/1.1/examples/tree.html".

 

In the example, the "Overlays" subtree hosted in the Layers panel contains 3 layer nodes each with a check box and a radio button, users can click on one of radio buttons to activate a layer, and through checking on/off check boxes, we can turn on/off the display of a layer. These functions are excellent.

 

Now the question is, I want to turn on/off a radio button in the treenode programmatically, also check on/off check boxs programmatically. Could anyone provide me some hints to achieve the goal? Do I need to examine some source code of the library?

 

Thanks,

Chamme
