Constructor Detail

PopupAction

public PopupAction()
Method Detail

initialize

protected void initialize()
Description copied from class: CallbackSystemAction
Initialize the action to have no performer.

Overrides:
initialize in class CallbackSystemAction

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

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
