public abstract class BaseAction
extends TextAction

This is the parent of majority of the actions. It implements the necessary resetting depending of what is required by constructor of target action. The other thing implemented here is macro recording.
Property "noIconInMenu" can be set to inform menu items not to use action's icon.

Method Detail

findValue

protected Object findValue(String key)

Deprecated. this method is deprecated like the LocaleSupport which it uses by default. It should be replaced by implementing getShortDescriptionBundleClass()

Find a value in resource bundles.

getValue

public Object getValue(String key)

Specified by:

getValue in interface Action

Overrides:

getValue in class AbstractAction

putValue

public void putValue(String key,
                     Object value)

Specified by:

putValue in interface Action

Overrides:

putValue in class AbstractAction

actionNameUpdate

protected void actionNameUpdate(String actionName)

Called by #putValue(String,String) when Action.NAME property is set to a non-null String value. This allows a "polymorphic" action (with Action.NAME-specific behavior) to update certain properties (e.g. an icon) according to the name that was set.

Parameters:

actionName - non-null action's name (value of Action.NAME property).

Since:

1.34

createDefaultValue

protected Object createDefaultValue(String key)

This method is called when there is no value for the particular key.
If the returned value is non-null it is remembered by putValue(String, Object) so in that case this method is only called once.

Note: When overriding this method super implementation should always be called.

Parameters:

key - key for which the default value should be found.

Returns:

default value or null if the default value does not exist for the given key.

getShortDescriptionBundleClass

protected Class getShortDescriptionBundleClass()

Get the class in a package where resource bundle for localization of the short description of this action resides.
By default this method returns null.

getDefaultShortDescription

protected Object getDefaultShortDescription()

Get the default value for Action.SHORT_DESCRIPTION property.
If this method returns non-empty value it will only be called once (its result will be remembered).

Returns:

value that will be use as result for Action.getValue(Action.SHORT_DESCRIPTION).

actionPerformed

public final void actionPerformed(ActionEvent evt)

This method is made final here as there's an important processing that must be done before the real action functionality is performed. It can include the following: 1. Updating of the target component depending on the update mask given in action constructor. 2. Possible macro recoding when the macro recording is turned on. The real action functionality should be done in the method actionPerformed(ActionEvent evt, JTextComponent target) which must be redefined by the target action.

actionPerformed

public abstract void actionPerformed(ActionEvent evt,
                                     JTextComponent target)

The target method that performs the real action functionality.

Parameters:

evt - action event describing the action that occured

target - target component where the action occured. It's retrieved by the TextAction.getTextComponent(evt).

asynchonous

protected boolean asynchonous()

getPopupMenuItem

public JMenuItem getPopupMenuItem(JTextComponent target)

getPopupMenuText

public String getPopupMenuText(JTextComponent target)

updateComponent

public void updateComponent(JTextComponent target)

Update the component according to the update mask specified in the constructor of the action.

Parameters:

target - target component to be updated.

updateComponent

public void updateComponent(JTextComponent target,
                            int updateMask)

Update the component according to the given update mask

Parameters:

target - target component to be updated.

updateMask - mask that specifies what will be updated
