To have your Pane fill the panel, it is best to use pack
at the main window level:
#!/usr/bin/perl
use Tk;
use Tk::Pane;
my $mw = MainWindow->new( -title => "SACL Survey" );
my $pane = $mw->Scrolled(qw/Pane -scrollbars osw/
)->pack(-fill => "both", -expand => 1);
$mw->Label( -text => "... <insert directions here> ..." )->pack();
for (1..30) {
$pane->Radiobutton(
-text => "button 1",
-value => "1",
-justify => "left",
-variable => \${"rb1_q$_"},
)->grid(
$pane->Radiobutton(
-text => "button 2",
-value => "2",
-justify => "left",
-variable => \${"rb2_q$_"},
),
$pane->Radiobutton(
-text => "button 3",
-value => "3",
-justify => "left",
-variable => \${"rb3_q$_"},
),
$pane->Radiobutton(
-text => "button 4",
-value => "4",
-justify => "left",
-variable => \${"rb4_q$_"},
));
}
MainLoop;
Note that the button sizes will not expand to fill the
window; the grid method creates a fixed grid. But the
pane, which uses pack, will adjust scroll bars according to
window size, even disappearing when not needed.
