Remove icon from tree node

[spiderweb]

I want the tree nodes to render without icons. I'm setting an iconCls: 'new-cls'
which is:

.new-cls {
    background-image: url('../../lib/ext/resources/images/default/s.gif');
}

but this class is just adding to the existing one (x-tree-node-icon). If I remove x-tree-node-icon class (in the firebug) I get the desired result, but how do I remove it before the tree renders?

I have the same problem and the only solution I found is to declare CSS class (new-cls in your case) like this:

.new-cls{
    background-image: none !important;
}

But this will leave an ugly white space between the text and the +/- icons. If you make it like this

.new-cls{
    background-image: none !important;
    width: 0 !important;
}

than it will be a nice looking tree without icons. Worked fine for me in FireFox, haven't tested it in IE.

Upd.: Works in IE as well.
