NAME¶
Tk::LabFrame - labeled frame.
SYNOPSIS¶
use Tk::LabFrame;
$f =
$parent->
LabFrame(?
-label=>
text,
-labelside=>
where, ...?);
DESCRIPTION¶
LabFrame is exactly like
Frame and additionally allows one to add
a label to the frame.
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.
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.
