Method Detail

surviveFocusChange

protected boolean surviveFocusChange()

Description copied from class: NodeAction

Specify the behavior of the action when a window with no activated nodes is selected. If the action should then be disabled, return false here; if the action should stay in the previous state, return true.

Note that NodeAction.getActivatedNodes() and NodeAction.performAction() are still passed the set of selected nodes from the old window, if you keep this feature on. This is useful, e.g., for an action like Compilation which should remain active even if the user switches to a window like the Output Window that has no associated nodes; then running the action will still use the last selection from e.g. an Explorer window or the Editor, if there was one to begin with.

Overrides:: surviveFocusChange in class NodeAction

Returns:: true in the default implementation

getName

public String getName()

Description copied from class: SystemAction

Get a human presentable name of the action. This may be presented as an item in a menu.

Using the normal menu presenters, an included ampersand before a letter will be treated as the name of a mnemonic.

Specified by:: getName in class SystemAction

Returns:: the name of the action

getHelpCtx

public HelpCtx getHelpCtx()

Description copied from class: SystemAction

Get a help context for the action.

Specified by:: getHelpCtx in interface HelpCtx.Provider
Specified by:: getHelpCtx in class SystemAction

Returns:: the help context for this action

iconResource

protected String iconResource()

Description copied from class: SystemAction

Specify the proper resource name for the action's icon. May be overridden by subclasses; the default is to have no icon. Typically this should be a 16x16 color GIF. Do not use relative paths nor an initial slash. If e.g. myIcon.gif is accompanied with myIcon_pressed.gif, myIcon_disabled.gif and/or myIcon_rollover.gif these images are used to call methods on JButton.setPressedIcon(), JButton.setDisabledIcon() and/or JButton.setRolloverIcon() with appropriate images. Please check Actions.connect(AbstractButton, Action) for additional info how this is achieved (using special "iconBase" key for getValue). As of APIs version 3.24, this path will be used for a localized search automatically.

Overrides:: iconResource in class SystemAction

Returns:: the resource name for the icon, e.g. com/mycom/mymodule/myIcon.gif; or null to have no icon (make a text label)

mode

protected int mode()

Description copied from class: CookieAction

Get the mode of the action: how strict it should be about cookie support.

Specified by:: mode in class CookieAction

Returns:: the mode of the action. Possible values are disjunctions of the MODE_XXX constants.

cookieClasses

protected Class[] cookieClasses()

Description copied from class: CookieAction

Get the cookies that this action requires. The cookies are disjunctive, i.e. a node must support AT LEAST ONE of the cookies specified by this method.

Specified by:: cookieClasses in class CookieAction

Returns:: a list of cookies

performAction

protected void performAction(Node[] activatedNodes)

Description copied from class: NodeAction

Perform the action based on the currently activated nodes. Note that if the source of the event triggering this action was itself a node, that node will be the sole argument to this method, rather than the activated nodes.

Specified by:: performAction in class NodeAction

Parameters:: activatedNodes - current activated nodes, may be empty but not null

asynchronous

protected boolean asynchronous()

Description copied from class: CallableSystemAction

If true, this action should be performed asynchronously in a private thread. If false, it will be performed synchronously as called in the event thread.

The default value is true for compatibility reasons; subclasses are strongly encouraged to override it to be false, and to either do their work promptly in the event thread and return, or to somehow do work asynchronously (for example using RequestProcessor.getDefault()).

You may currently set the global default to false by setting the system property org.openide.util.actions.CallableSystemAction.synchronousByDefault to true.

When true, the current implementation also provides for a wait cursor during the execution of the action. Subclasses which override to return false should consider directly providing a wait or busy cursor if the nature of the action merits it.

Overrides:: asynchronous in class CallableSystemAction

Returns:: true if this action should automatically be performed asynchronously
