Method Detail

handleEvent

public boolean handleEvent(IdeAction action,
                           Context context)

Description copied from interface: Controller

This method is called when a user interaction with a View triggers the execution of a command.

Specified by:

handleEvent in interface Controller

Parameters:

action - action whose command is to be executed.

Returns:

true if the controller handles the specified command.

update

public boolean update(IdeAction action,
                      Context context)

Description copied from interface: Controller

This method updates the enabled status of the specified action within the specified context. It should generally be called on the controller associated with the active view to allow that controller to take the first crack at determining its enabled status. If that controller wants to update its enabled status, it does so and returns true to indicate that further controllers do not need to be consulted. If the controller does not deal with setting the enabled status of an action, it delegates the request to its supervising controller, all the way up to the Ide. The Ide has a special implementation of update(xx) that further delegates the request to root controllers, until one of them returns true indicating the request was handled by the controller.

Specified by:

update in interface Controller

Parameters:

action - action whose command is to be executed.

context - the current context

Returns:

true if the controller handles the specified command.
