DESCRIPTION
       The  iwidgets::labeledwidget  command creates a labeled widget which contains a label and child site.
       The child site is a frame which can filled with any widget via a derived class or though the  use  of
       the  childsite method.  This class was designed to be a general purpose base class for supporting the
       combination of label widget and a childsite.  The options include the ability to position  the  label
       around the childsite widget, modify the font and margin, and control the display of the labels.


METHODS
       The  iwidgets::labeledwidget  command creates a new Tcl command whose name is pathName.  This command
       may be used to invoke various operations on the widget.  It has the following general form:

              pathName option ?arg arg ...?

       Option and the args determine the exact behavior of the command.  The following commands are possible
       for labeledwidget widgets:

WIDGET-SPECIFIC METHODS
       pathName childsite
              Return the path name of the child site.

       pathName cget option
              Returns the current value of the configuration option given by option.  Option may have any of
              the values accepted by the iwidgets::labeledwidget command.

       pathName configure ?option? ?value option value ...?
              Query or modify the configuration options of the widget.  If no option is specified, returns a
              list  describing  all of the available options for pathName (see Tk_ConfigureInfo for informa-
              tion on the format of this list).  If option is specified with  no  value,  then  the  command
              returns a list describing the one named option (this list will be identical to the correspond-ing corresponding
              ing sublist of the value returned if no option is specified).  If  one  or  more  option-value
              pairs  are  specified,  then the command modifies the given widget option(s) to have the given
              value(s);  in this case the command returns an empty string.  Option may have any of the  val-ues values
              ues accepted by the iwidgets::labeledwidget command.


STATIC METHODS
       iwidgets::Labeledwidget::alignlabels widget ?widget ...?
              The  alignlabels  procedure  takes  a list of widgets derived from the Labeledwidget class and
              uses the label margin to make each widget have the same total space  for  the  combination  of
              label and margin.  The net effect is to left align the labels.  Generally, this method is only
              useful with a label position of w, which is the default.


COMPONENTS
       Name:           label
       Class:          label

              The label component provides the label for the labeled widget.  See the "label" widget  manual
              entry for details on the label component item.

       Name:           lwchildsite
       Class:          frame

              The lwchildsite component is the user child site for the labeled widget.  See the "frame" wid-get widget
              get manual entry for details on the lwchildsite component item.


EXAMPLE
              The labeledwidget was primarily meant to be a base class.  The ScrolledListBox and  EntryField
              are  good  examples  of derived classes of the labeledwidget class.  In order to provide equal
              support for composite classes, the 'childsite' methods also exists.  The following is an exam-ple example
              ple of 'childsite' method usage.


               package require Iwidgets 4.0
               iwidgets::labeledwidget .lw -labeltext "Canvas Widget" -labelpos s
               pack .lw -fill both -expand yes -padx 10 -pady 10

               set cw [canvas [.lw childsite].c -relief raised -width 200 -height 200]
               pack $cw -padx 10 -pady 10
