Example 1 with IContextMenu

use of org.eclipse.scout.rt.client.ui.action.menu.root.IContextMenu in project scout.rt by eclipse.

the class MenuUtility method getMenuByClass.

/**
 * @return the sub-menu of the given context menu owner that implements the given type. If no implementation is found,
 *         <code>null</code> is returned. Note: This method uses instance-of checks, hence the menu replacement
 *         mapping is not required.
 * @throws IllegalStateException
 *           when more than one menu implements the given type
 * @throws IllegalArgumentException
 *           when no context menu owner is provided.
