Because the action is shared, it must have a way of getting it's target to act upon. This class provides support to try and find a text component to operate on. The preferred way of getting the component to act upon is through the ActionEvent that is received. If the Object returned by getSource can be narrowed to a text component, it will be used. If the action event is null or can't be narrowed, the last focused text component is tried. This is determined by being used in conjunction with a JTextController which arranges to share that information with a TextAction. <p> <strong>Warning:</strong> 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. A future release of Swing will provide support for long term persistence.<P><DL><DT><B>See Also: </B><DD><A HREF="../../../serialized-form.html#javax.swing.text.TextAction">Serialized Form</A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="fields_inherited_from_class_javax.swing.AbstractAction"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from class javax.swing.<A HREF="../../../javax/swing/AbstractAction.html">AbstractAction</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../../javax/swing/AbstractAction.html#changeSupport">changeSupport</A>, <A HREF="../../../javax/swing/AbstractAction.html#enabled">enabled</A></CODE></TD></TR></TABLE> <A NAME="fields_inherited_from_class_javax.swing.Action"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from interface javax.swing.<A HREF="../../../javax/swing/Action.html">Action</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../../javax/swing/Action.html#ACCELERATOR_KEY">ACCELERATOR_KEY</A>, <A HREF="../../../javax/swing/Action.html#ACTION_COMMAND_KEY">ACTION_COMMAND_KEY</A>, <A HREF="../../../javax/swing/Action.html#DEFAULT">DEFAULT</A>, <A HREF="../../../javax/swing/Action.html#LONG_DESCRIPTION">LONG_DESCRIPTION</A>, <A HREF="../../../javax/swing/Action.html#MNEMONIC_KEY">MNEMONIC_KEY</A>, <A HREF="../../../javax/swing/Action.html#NAME">NAME</A>, <A HREF="../../../javax/swing/Action.html#SHORT_DESCRIPTION">SHORT_DESCRIPTION</A>, <A HREF="../../../javax/swing/Action.html#SMALL_ICON">SMALL_ICON</A></CODE></TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../javax/swing/text/TextAction.html#TextAction(java.lang.String)">TextAction</A></B>(<A HREF="../../../java/lang/String.html">String</A> name)</CODE><BR> Creates a new JTextAction object.</TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static <A HREF="../../../javax/swing/Action.html">Action</A>[]</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/text/TextAction.html#augmentList(javax.swing.Action[], javax.swing.Action[])">augmentList</A></B>(<A HREF="../../../javax/swing/Action.html">Action</A>[] list1, <A HREF="../../../javax/swing/Action.html">Action</A>[] list2)</CODE><BR> Takes one list of commands and augments it with another list of commands.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected <A HREF="../../../javax/swing/text/JTextComponent.html">JTextComponent</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/text/TextAction.html#getFocusedComponent()">getFocusedComponent</A></B>()</CODE><BR>⌨️ 快捷键说明
