Widget defines most of the behaviour needed: Widgets are created by the user with a particular parent, and then "pack"ed in order to draw them on the screen. All widgets have three essential things: a widget name used when running Tcl code, an Objective C name when sending messages from Tcl to those objects, and a parent.<P><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== 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> java.lang.Object</CODE></FONT></TD><TD><CODE><B><A HREF="../../swarm/gui/WidgetC.html#createParent(java.lang.Object)">createParent</A></B>(java.lang.Object parent)</CODE><BR> When a widget is created it needs to be given a parent.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../swarm/gui/WidgetC.html#makeWidgetNameFor(java.lang.Object)">makeWidgetNameFor</A></B>(java.lang.Object widget)</CODE><BR> Compute the widget name for a component widget.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.lang.Object</CODE></FONT></TD><TD><CODE><B><A HREF="../../swarm/gui/WidgetC.html#setParent(java.lang.Object)">setParent</A></B>(java.lang.Object parent)</CODE><BR> Set the containing window of the widget.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.lang.Object</CODE></FONT></TD><TD><CODE><B><A HREF="../../swarm/gui/WidgetC.html#setWidgetNameFromParent(swarm.gui.Widget)">setWidgetNameFromParent</A></B>(<A HREF="../../swarm/gui/Widget.html">Widget</A> parent)</CODE><BR> Set the widget name using the parent as context.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.lang.Object</CODE></FONT></TD><TD><CODE><B><A HREF="../../swarm/gui/WidgetC.html#setWidgetNameFromParentName(java.lang.String)">setWidgetNameFromParentName</A></B>(java.lang.String parentWidgetName)</CODE><BR> Set the widget name using a hypothetical parent name.</TD></TR></TABLE> <A NAME="methods_inherited_from_class_swarm.defobj.CreateC"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods inherited from interface swarm.defobj.<A HREF="../../swarm/defobj/CreateC.html">CreateC</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../swarm/defobj/CreateC.html#create(swarm.defobj.Zone)">create</A>, <A HREF="../../swarm/defobj/CreateC.html#createBegin(swarm.defobj.Zone)">createBegin</A>, <A HREF="../../swarm/defobj/CreateC.html#createEnd()">createEnd</A></CODE></TD></TR></TABLE> <A NAME="methods_inherited_from_class_swarm.defobj.CustomizeC"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods inherited from interface swarm.defobj.<A HREF="../../swarm/defobj/CustomizeC.html">CustomizeC</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../swarm/defobj/CustomizeC.html#customizeBegin(java.lang.Object)">customizeBegin</A>, <A HREF="../../swarm/defobj/CustomizeC.html#customizeCopy(java.lang.Object)">customizeCopy</A>, <A HREF="../../swarm/defobj/CustomizeC.html#customizeEnd()">customizeEnd</A></CODE></TD></TR></TABLE> <P><!-- ============ FIELD DETAIL =========== --><!-- ========= CONSTRUCTOR DETAIL ======== --><!-- ============ METHOD DETAIL ========== --><A NAME="method_detail"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=1><FONT SIZE="+2"><B>Method Detail</B></FONT></TD></TR></TABLE><A NAME="createParent(java.lang.Object)"><!-- --></A><H3>createParent</H3><PRE>public java.lang.Object <B>createParent</B>(java.lang.Object parent)</PRE><DL><DD>When a widget is created it needs to be given a parent.
