[Users] button to uncheck all the layers in my Ext.tree.TreePanel

[Jacinto Estima]

Thanks Bart. I followed your recommendation to loop over the layers and it's
working.

 

Regards,

Jacinto

The function argument of cascade gets a node argument, use that in function
f instead of LayerTree.

 

Alternatively, just loop over the layers and call setVisibility(false), the
tree will update itself.

 

Best regards,

Bart

Hi,

 

I am trying to develop a button to uncheck all the layers in my
Ext.tree.TreePanel but without success so far.

Does anyone have ideas?

 

I'm using the following code that I've found:

 

var unckeckAll = new Ext.Button({

              text: "Uncheck All",

              listeners:{

                     reset: function (){

                   startNode = LayerTree.root;

                   var f = function () {

                       if (LayerTree.attributes.checked) {

                            LayerTree.attributes.checked = false;

                            LayerTree.getUI().toggleCheck(false);

                       }

                   };

                   startNode.cascade(f);

               }

           }           

       });

 

Thanks,

Jacinto
