public class ItemTree
extends javax.swing.JTree
implements ItemFilterListener

The item browser displays the models of the system and their items in a tree structure. It supports dragging an item (e. g. onto the workspace).
The items can be filtered by the installed item filters (currently item type and item text filter). The filter components (used to adjust the filters) are shown in a panel above the tree and can be turned on and off using the item filter buttons in the plugin's toolbar.
