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

performAction

public abstract void performAction()
Actually perform the action. This is the method which should be called programmatically. Presenters in Actions use this.

See SystemAction.actionPerformed(java.awt.event.ActionEvent) for a note on threading usage: in particular, do not access GUI components without explicitly asking for the AWT event thread!


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
