Tk::LabFrame - labeled frame.
$f = $parent->LabFrame(?-label=>text, -labelside=>where, ...?);
LabFrame is exactly like Frame and additionaly allows 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.
Frame used to display the border
Frame used to create new LabFrame children.
Label used for displaying text
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;
Perhaps LabFrame should be subsumed within the generic pTk labeled widget mechanism.
