ExtJS 3.4 - setLoading

Question

I am using ExtJS 3 now, and I really miss setLoading function from ExtJS 4.

Looked throght the docs carefully, did not find it.

How can I set/remove loading state on any component in ExtJS 3.4?

Answer 1

You should create a new LoadMask Object for the component

var loadMask = new Ext.LoadMask(cmp, {msg:'Wait message'});

and then you can show or hide the mask

loadMask.show(); 
loadMAsk.hide();
