Examples of javax.swing.tree.FixedHeightLayoutCache$FHTreeStateNode

javax.swing.tree.FixedHeightLayoutCache
FHTreeStateNode is used to track what has been expanded. FHTreeStateNode differs from VariableHeightTreeState.TreeStateNode in that it is highly model intensive. That is almost all queries to a FHTreeStateNode result in the TreeModel being queried. And it obviously does not support variable sized row heights.

    protected TreeExpansionListener createTreeExpansionListener() {
        return new TreeExpansionHandler();
    }


    protected AbstractLayoutCache createLayoutCache() {
        return rowHeight > 0 && largeModel ? (AbstractLayoutCache)new FixedHeightLayoutCache()
                                           : (AbstractLayoutCache)new VariableHeightLayoutCache();
    }
