- All Implemented Interfaces:
- Action, ActionListener, EventListener, Externalizable, Presenter, Presenter.Menu, Presenter.Popup, Presenter.Toolbar, Serializable
- Direct Known Subclasses:
- BuildProjectAction, CompileProjectAction, DebugProjectAction, ExecuteProjectAction, SaveProjectAction
- public abstract class ProjectSensitiveAction
- extends CallableSystemAction
Base class for all project sensitive actions. Attaches listener
to changes of project desktop (TopManager.PROP_PLACES) and also to
cookie changes on current project desktop. If either one is changed,
the enable method is called to enable/disable the action. When
enabled and invoked the method performAction (Node) is called.

ProjectSensitiveAction
public ProjectSensitiveAction()
initialize
protected void initialize()
- Description copied from class:
SystemAction
- Initialize the action.
The default implementation just enabled it.
- Overrides:
initialize
in class SystemAction
addNotify
protected void addNotify()
- Description copied from class:
SharedClassObject
- Notify subclasses that the first listener has been added to this action.
The default implementation does nothing.
- Overrides:
addNotify
in class SharedClassObject
removeNotify
protected void removeNotify()
- Description copied from class:
SharedClassObject
- Notify subclasses that the last listener has been removed from this action.
The default implementation does nothing.
- Overrides:
removeNotify
in class SharedClassObject
isEnabled
public boolean isEnabled()
- Test for enablement based on
enable(org.openide.nodes.Node)
.
You probably ought not override this, except possibly
to call the super method and add an additional check.
- Overrides:
isEnabled
in class SystemAction
- Returns:
true
to enable
actionPerformed
public void actionPerformed(ActionEvent ev)
- Description copied from class:
SystemAction
- Actually perform the action.
Specified in
ActionListener.actionPerformed(java.awt.event.ActionEvent)
.
In some cases, the implementation may have an empty body,
if the presenters handle the performing of the action in a different way
than by calling this method.
- Overrides:
actionPerformed
in class CallableSystemAction
- Following copied from class:
org.openide.util.actions.SystemAction
- Parameters:
ev
- the event triggering the action
performAction
public void performAction()
- Performs the action.
In the default implementation, calls
performAction(Node)
.
In general you need not override this.
- Overrides:
performAction
in class CallableSystemAction
performAction
protected abstract void performAction(Node project)
- Performs the action on the current project desktop node.
- Parameters:
project
- desktop node
enable
protected abstract boolean enable(Node project)
- Performs the action on the current project desktop node.
- Parameters:
project
- desktop node- Returns:
true
to be enabled, false
to be disabled
