Beschreibung
The tree has a right-click popup menu that allows the user to insert, delete, and edit items. Set disablePopup to true to disable this popup menu.
Even if the popup is disabled, the user can still edit the items by clicking twice or pressing F2, and insert and delete items by pressing Ins and Del. Set allowEditLabels and allowEditTree to false to prevent these actions.
