All Implemented Interfaces:
Action, ActionListener, ContextAwareAction, EventListener, Externalizable, HelpCtx.Provider, Presenter, Presenter.Menu, Presenter.Popup, Presenter.Toolbar, Serializable
public class CopyAction
extends CallbackSystemAction

Copy the selected item to the clipboard. As callback action this class cooperate with other actions placed in JComponent ActionMap. As a key to the ActionMap the javax.swing.text.DefaultEditorKit.copyAction is used.

Constructor Detail

CopyAction

public CopyAction()
Method Detail

initialize

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

Overrides:
initialize in class CallbackSystemAction

getActionMapKey

public Object getActionMapKey()
Description copied from class: CallbackSystemAction
Getter for action map key, which is used to find action from provided context (i.e. ActionMap provided by the context), which acts as a callback. Override this method in subclasses to provide 'nice' key.

Overrides:
getActionMapKey in class CallbackSystemAction
Returns:
key which is used to find the action which performs callback, default returned key is a class name.

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)

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
