Method Detail

constructPopup

public void constructPopup(PopupMenuBuilder builder,
                           ComponentBuilderData compData)
                    throws FormActionException

Asks this handler to create a popup menu using the specified PopupMenuBuilder. An implementation can use the methods offered by the builder to create a menu with arbitrary actions and sub menus. On calling the builder's create() method the menu will be displayed. The ComponentBuilderData object is a source of all available information: through the BeanContext accessible through this object many important objects can be obtained including the current form or the ActionStore. So all actions required by the PopupMenuHandler should be reachable through this object. Dynamically creates the context menu based on the enabled state of the actions affected.

Specified by:

constructPopup in interface PopupMenuHandler

Parameters:

builder - the builder for creating the menu

compData - the current ComponentBuilderData object providing access to lots of context information

Throws:

FormActionException - if an error occurs when creating the menu
