All Implemented Interfaces:

ActionListener, Runnable, EventListener

public abstract class ContextMenuAction
extends Object
implements ActionListener, Runnable

Base functionality for an entry in a TableContextMenu.

This implementation delays the execution of the context menu action with SwingUtilities.invokeLater(Runnable) in order to avoid redraw problems when the popup menu is closed.

Field Detail

mAdapter

protected ContextMenuAdapter mAdapter

With this reference we can get information about the table we work on. The information is only guaranteed to be vaild while we are called by TableContextMenu.

Constructor Detail

ContextMenuAction

public ContextMenuAction()

Method Detail

initialize

public void initialize(ContextMenuAdapter pAdapter)

This gets call by the TableContextMenu to give us access to information about the table we work on.

Parameters:

pAdapter - table information source

actionPerformed

public void actionPerformed(ActionEvent pEvent)

Implementation of the ActionListener interface. We do not react on this event immediately. Instead we use SwingUtilities.invokeLater(Runnable) to complete the event processing before we take further steps in run(). This eliminates redraw problems in Swing.

Specified by:

actionPerformed in interface ActionListener

Parameters:

pEvent - action event

run

public void run()

Implementation of the Runnable interface. This will get called by SwingUtilities.invokeLater(Runnable) when everything is ready to for us to do our processing. This method will call performAction().

Specified by:

run in interface Runnable

getKennung

public abstract String getKennung()

An identifier for this context menu action. This identifier is used by the TableContextMenu to get resource information from the SwingDecorator. The returned identifier should be prefixed with ContextMenuAdapter.getContextMenuKennung() to ensure uniqueness.

This method must be implemented by child classes.

Returns:

a I18N identifier for this context menu action

isEnabled

public abstract boolean isEnabled()

The TableContextMenu will call this method just before poping up the menu in order to enable/disable the menu entries. All the necessary information is available via mAdapter.

This method must be implemented by child classes.

Returns:

true if this action is able to execute

performAction

public abstract void performAction()

Here the processing takes place when the user selects this context menu entry. All the necessary information is available via mAdapter.

This method must be implemented by child classes.
