RE: Scrolling a window

Another related question:  how do I get the initial size to be just
large enough so that there are not scroll bars needed?  So, for the
sample in the last post, how would I get it so the window is initially
large enough to show all the (400) buttons?

Oh, that works.  Thanks!  I must have had it wrong, but that was several
edit cycles ago so I can't see what I had :)

BWidget ScrollableFrame
http://docs.activestate.com/activetcl/8.5/bwidget/ScrollableFrame.html

Example rewritten to use grid.

use strict;
use Tkx;
Tkx::package_require("BWidget");

my $mw = Tkx::widget->new(".");
my $sw = $mw->new_ScrolledWindow();
my $sf = $sw->new_ScrollableFrame();

$sw->setwidget($sf);
#$sw->g_pack(-fill => "both", -expand => 1); $sw->g_grid(-sticky =>
"nsew"); # In Tk 8.4, you must use '0' instead of $sw below. Tk 8.5 will
find # the row/col based on widget reference Tkx::grid(rowconfigure =>
$mw, $sw, -weight => 1); Tkx::grid(columnconfigure => $mw, $sw, -weight
=> 1);

my $subf = Tkx::widget->new($sf->getframe());

my $b;
for my $i (1..20) {
     for my $j (1..20) {
	$b = $subf->new_ttk__button(-text => "$i,$j",
				    -command => sub {exit;});
	$b->g_grid(-row => $i, -column => $j);
     }
}

Tkx::MainLoop;

Enjoy,
