Re: Tk and scrollbars

[SciDude]

Did you want the single quotes around '-wrap' and '-width' ?

Also, your "very long line" had line breaks in my downloaded version. Here are my modest hacks to activate the horizontal scroll bar:

#!/usr/bin/perl

use strict;
use Tk;

my ($mainwindow, $menubar, $display, $text);

my $counter = 0;

$mainwindow = new MainWindow;
$mainwindow->geometry("800x400");

$display = $mainwindow->Scrolled('Text', -relief=>'sunken',
-borderwidth=>'2',
  -height=>'24', -scrollbars=>'se', '-width' => 40, -wrap=>'none');
$display->pack(-expand=>'1', -fill=>'both');

$text =  $display->Subwidget('text', -scrollbars=>'se', -wrap=>'none')
+;           # need this because you can't tie to $display - main widg
+et
tie *STDOUT, ref $text, $text;

create_gui_main();

$text->repeat(
  1000, sub {
    goto \&mymain;
  },
);

MainLoop;

sub mymain() {
  # This would normally be real text
  $counter++;
  print "this is a very long line we need a scrollbar on the x axis...
+..... this is a very long line we need a scrollbar on the x axis.....
+... this is a very long line we need a scrollbar on the x axis.......
+. well the number is current = " . $counter . " \n";
}

# ------------------------ #
sub quitapp() {
  exit;
}

# ------------------------ #
sub create_gui_main {
  my $menuitems = [
    [Cascade => "~File", -menuitems => [
        [Button => "~Quit", -command => \&quitapp],
      ]
    ],
  ];
  if ($Tk::VERSION >= 800) {
    $menubar = $mainwindow->Menu(-menuitems => $menuitems);
      $mainwindow->configure(-menu => $menubar);
  } else {
    $mainwindow->Menubutton(-text => "Pseudo menubar",
      -menuitems => $menuitems)->pack;
  }
}
