Class Overview

A ContextMenu is displayed when the end user makes click using the right mouse button on an element in the interface; the menu displays a list with different actions associated with that element.

A ContextMenu is basically a collection of ContextMenuItem objects. Each ContextMenuItem represents a single option to the end user.

Context menus can and should be configured using external xml files. All Microstrategy Web transforms that display context-menus have their contextMenus formal parameter assigned in the style catalog. Even those transforms that display no context menus out of the box can be configured to display them simply by creating a new xml definition file and setting the contextMenus formal parameter.

Optionally, a ContextMenu can be populated programatically using one of the several addItem methods it exposes. Once populated, the ContextMenu should be attached to the corresponding HTML tag by calling the attachTo(Tag) method or by appending the necessary attributes returned by the getTriggerString()
