All Implemented Interfaces:
Action, Cloneable, Serializable
An action to set paragraph alignment. This sets the
StyleConstants.Alignment attribute for the
currently selected range of the target JEditorPane.
This is done by calling
StyledDocument.setParagraphAttributes
on the styled document associated with the target
JEditorPane.
If the target text component is specified as the
source of the ActionEvent and there is a command string,
the command string will be interpreted as an integer
that should be one of the legal values for the
StyleConstants.Alignment attribute.
Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running
the same version of Swing. As of 1.4, support for long term storage
of all JavaBeansTM
has been added to the java.beans package.
Please see java.beans.XMLEncoder .
