<H2>DESCRIPTION</H2><PRE>
The <STRONG>labeledwidget</STRONG> 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.
</PRE>
<H2>METHODS</H2><PRE>
The <STRONG>labeledwidget</STRONG> command creates a new Tcl command whose
name is <EM>pathName</EM>. This command may be used to invoke vari-
ous operations on the widget. It has the following general
form:
<EM>pathName</EM> <EM>option</EM> ?<EM>arg</EM> <EM>arg</EM> ...?
<EM>Option</EM> and the <EM>arg</EM>s determine the exact behavior of the com-
mand. The following commands are possible for labeledwidget
widgets:
</PRE>
<H2>WIDGET-SPECIFIC METHODS</H2><PRE>
<EM>pathName</EM> <STRONG>childsite</STRONG>
Return the path name of the child site.
<EM>pathName</EM> <STRONG>cget</STRONG> <EM>option</EM>
Returns the current value of the configuration option
given by <EM>option</EM>. <EM>Option</EM> may have any of the values
accepted by the <STRONG>labeledwidget</STRONG> command.
<EM>pathName</EM> <STRONG>configure</STRONG> ?<EM>option</EM>? ?<EM>value</EM> <EM>option</EM> <EM>value</EM> ...?
Query or modify the configuration options of the
widget. If no <EM>option</EM> is specified, returns a list
describing all of the available options for <EM>pathName</EM>
(see <STRONG>Tk_ConfigureInfo</STRONG> for information on the format of
this list). If <EM>option</EM> is specified with no <EM>value</EM>, then
the command returns a list describing the one named
option (this list will be identical to the correspond-
ing sublist of the value returned if no <EM>option</EM> is
specified). If one or more <EM>option</EM> - <EM>value</EM> 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. <EM>Option</EM> may have any
of the values accepted by the <STRONG>labeledwidget</STRONG> command.
</PRE>
<H2>STATIC METHODS</H2><PRE>
<STRONG>Labeledwidget::alignlabels</STRONG> <EM>widget</EM> ?<EM>widget</EM> ...?
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.
</PRE>
<H2>COMPONENTS</H2><PRE>
Name: <STRONG>label</STRONG>
Class: <STRONG>label</STRONG>
The label component provides the label for the labeled
widget. See the "label" widget manual entry for
details on the label component item.
Name: <STRONG>lwchildsite</STRONG>
Class: <STRONG>frame</STRONG>
The lwchildsite component is the user child site for
the labeled widget. See the "frame" widget manual
entry for details on the lwchildsite component item.
</PRE>
<H2>EXAMPLE</H2><PRE>
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 fol-
lowing is an example of 'childsite' method usage.
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
