Possible to selectively render Nodes in a TreePanel with TreeStore<BaseTreeModel>

[richardcatlin]

How can I selectively show TreeNodes in the TreePanel from a TreeStore?

Is it possible to add a Property to BaseTreeModel, such as a boolean render, such that the TreePanel will hide or show the Node?

Thank you.

Hi.
You can use a StoreFilter for this.
Take a look in its definition.
Basically, you just need to implement the select method.
Return true for the nodes you want to show, and false for the ones you want to hide.

Hope this helps you.

Thanks. That works. Here's the code for others with the same problem.
StoreFilter<BaseTreeModel> storeFilter = new StoreFilter<BaseTreeModel>() {
@Override
public boolean select(Store<BaseTreeModel> store, BaseTreeModel parent, BaseTreeModel item, String property) {
Boolean render = item.get("render");
return render;
}
};
store1.addFilter(storeFilter);
store1.applyFilters(null);
