NAME ^

Tk::LabFrame - labeled frame.

SYNOPSIS ^

 use Tk::LabFrame;

 $f = $parent->LabFrame(?-label=>text, -labelside=>where, ...?);

DESCRIPTION ^

LabFrame is exactly like Frame and additionaly allows to add a label to the frame.

WIDGET-OPTIONS ^

LabFrame supports the same options as the Frame widget.

Additional options of LabFrame are:

-font => font

Specifies the label's font

-foreground => color

Specifies the label's foreground color

-label => text

The text of the label to be placed with the Frame.

-labelside => where

Where can be one of left, right, top, bottom or acrosstop. The first four work as might be expected and place the label to the left, right, above or below the frame respectively. The 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.

-labelvariable => 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.

ADVERTISED SUBWIDGETS ^

See "Subwidget" in Tk::mega how to use advertised widgets.

border
  Frame used to display the border
frame
  Frame used to create new LabFrame children. 
label
  Label used for displaying text

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;

BUGS ^

Perhaps LabFrame should be subsumed within the generic pTk labeled widget mechanism.
