All Implemented Interfaces:
Action, ActionListener, EventListener, Externalizable, Presenter, Presenter.Menu, Presenter.Popup, Presenter.Toolbar, Serializable

public abstract class BooleanStateAction
extends SystemAction
implements Presenter.Menu, Presenter.Popup, Presenter.Toolbar

An action that can be toggled on or off. The actual "performing" of the action is the toggle itself, so this action should be used by listening to the PROP_BOOLEAN_STATE property.

The default value of the state is true (on).

Method Detail

getMenuPresenter

public JMenuItem getMenuPresenter()
Description copied from interface: Presenter.Menu
Get a menu item that can present this action in a JMenu.
Specified by:
getMenuPresenter in interface Presenter.Menu
Following copied from interface: org.openide.util.actions.Presenter.Menu
Returns:
the representation for this action

getPopupPresenter

public JMenuItem getPopupPresenter()
Description copied from interface: Presenter.Popup
Get a menu item that can present this action in a JPopupMenu.
Specified by:
getPopupPresenter in interface Presenter.Popup
Following copied from interface: org.openide.util.actions.Presenter.Popup
Returns:
the representation for this action

getToolbarPresenter

public Component getToolbarPresenter()
Description copied from interface: Presenter.Toolbar
Get a component that can present this action in a JToolBar.
Specified by:
getToolbarPresenter in interface Presenter.Toolbar
Following copied from interface: org.openide.util.actions.Presenter.Toolbar
Returns:
the representation for this action

getBooleanState

public boolean getBooleanState()
Get the current state.
Returns:
true if on

setBooleanState

public void setBooleanState(boolean value)
Set the current state. Fires a change event, which should be used to affect other components when its state is toggled.
Parameters:
value - true to turn on, false to turn off

initialize

protected void initialize()
Description copied from class: SystemAction
Initialize the action. The default implementation just enabled it.
Overrides:
initialize in class SystemAction

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.

When run in the normal way from the action manager (e.g. as part of a standard menu or toolbar presenter), the action body can block and take time, but needs to explicitly ask to enter the AWT event thread if doing any GUI work. See the Threading Models document in API documentation for details.

Overrides:
actionPerformed in class SystemAction
Following copied from class: org.openide.util.actions.SystemAction
Parameters:
ev - the event triggering the action
