OpenAction

public OpenAction()

Method Detail

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.

Overrides:

cookieClasses in class CookieAction

Following copied from class: org.openide.util.actions.CookieAction

Returns:

a list of cookies

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

Following copied from class: org.openide.util.actions.NodeAction

Returns:

true in the default implementation

mode

protected int mode()

Description copied from class: CookieAction

Get the mode of the action, i.e. how strict it should be about cookie support.

Overrides:

mode in class CookieAction

Following copied from class: org.openide.util.actions.CookieAction

Returns:

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

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.

Overrides:

getName in class SystemAction

Following copied from class: org.openide.util.actions.SystemAction

Returns:

the name of the action

getHelpCtx

public HelpCtx getHelpCtx()

Description copied from class: SystemAction

Get a help context for the action.

Overrides:

getHelpCtx in class SystemAction

Following copied from class: org.openide.util.actions.SystemAction

Returns:

the help context for this action

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.

Overrides:

performAction in class NodeAction

Following copied from class: org.openide.util.actions.NodeAction

Parameters:

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