GXT 3.0 Tree - How to display custom icon per tree node?

[DavidHoffer]

I need to display a multi-level tree and show various icons per tree node. In the demo examples all I see are images set at the root tree level, i.e. one TreeStyle for the entire tree. How can I display different icons at each of the tree nodes/levels?

Looks like you need to implement an IconProvider and pass it to the Tree.

        tree.setIconProvider(new IconProvider<SideMenuDto>() {


            @Override
            public ImageResource getIcon(SideMenuDto p_model) {
                return  .... // your icon choosing algorithm
            }
        });

where SideMenuDto is my tree item object. Use your own in your case.

Yeah that works perfectly, plus I found I can dynamically update the icons which is what I need to do by calling refresh on the tree. Thanks.
