Interface Controller
- All Known Implementing Classes:
- AbstractCanvasController, AbstractLogManager, CodeEditorController, DockStation, EditorManager, FileOpenHistory, JCompiler, JProjectStructureController, LogManager, MultiManager, ObjectGalleryAddin, PrintManager, VCSController, WindowManager, WizardManager
- public interface Controller
Each View
has an associated Controller
. Controllers receive requests to handle the commands associated with user actions. The controller's handleEvent
method gets called with the appropriate Command
specified. If the Controller
does not handle the requested command it delegates the Command
to a supervising Controller
. Controllers are also responsible for determining the availability of a specific command. The update
method is called to do just that.

handleEvent
public boolean handleEvent(IdeAction action,
Context context)
- This method is called when a user interaction with a
View
triggers the execution of a command.
-
- 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)
- 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.
-
- Parameters:
action
- action whose command is to be executed.
context
- the current context
- Returns:
- true if the controller handles the specified command.
