=head1 NAME
Tk::LabFrame - labeled frame.
=for pm Tixish/LabFrame.pm
=for category Tix Extensions
=head1 SYNOPSIS
S< >B<use Tk::LabFrame;>
S< >I<$f> = I<$parent>-E<gt>B<LabFrame>(?B<-label>=E<gt>I<text>,
B<-labelside>=E<gt>I<where>, ...?);
=head1 DESCRIPTION
B<LabFrame> is exactly like B<Frame> and additionaly allows to
add a label to the frame.
=head1 WIDGET-OPTIONS
B<LabFrame> supports the same options as the
L<Frame|Tk::Frame/"STANDARD OPTIONS"> widget.
Additional options of B<LabFrame> are:
=over 4
=item B<-font> =E<gt> I<font>
Specifies the label's font
=item B<-foreground> =E<gt> I<color>
Specifies the label's foreground color
=item B<-label> =E<gt> I<text>
The text of the label to be placed with the Frame.
=item B<-labelside> =E<gt> I<where>
I<Where> can be one of B<left>, B<right>, B<top>, B<bottom> or B<acrosstop>.
The first four work as might be expected and place the label to the
left, right, above or below the frame respectively. The B<acrosstop>
creates a grooved frame around the central frame and puts the label
near the northwest corner such that it appears to "overwrite" the
groove.
=item B<-labelvariable> =E<gt> I<scalar_ref>
Specifies a reference to a variable and used as an
alternative to -label. If the value of the variable changes,
then the widget will be updated automatically to reflect the
change. Used like -textvariable.
=back
=head1 ADVERTISED SUBWIDGETS
See L<Tk::mega/"Subwidget"> how to use advertised widgets.
=over 4
=item I<border>
Frame used to display the border
=item I<frame>
Frame used to create new LabFrame children.
=item I<label>
Label used for displaying text
=back
=head1 EXAMPLE
Run the following test program to see this in action:
use strict;
use Tk;
require Tk::LabFrame;
require Tk::LabEntry;
my $test = 'Test this';
my $mw = Tk::MainWindow->new;
my $f = $mw->LabFrame(-label => "This is a label",
-labelside => "acrosstop");
$f->LabEntry(-label => "Testing", -textvariable => \$test)->pack;
$f->pack;
Tk::MainLoop;
=head1 BUGS
Perhaps B<LabFrame> should be subsumed within the generic pTk
labeled widget mechanism.
