Sure! If you need some explanation, just ask.
function unchecNodes(node) {
for (var counter = 5; counter < map.layers.length; ++counter) {
map.layers[counter].setVisibility(false);
}
}
var unckeckAll = new Ext.Button({
text: "Uncheck All",
handler: unchecNodes
});

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
