juo has asked for the wisdom of the Perl Monks concerning the following question:

I would like to create a widget which is using the Text option and the pack function in combination with the Scrollbar function. I have not been able to let the horizontal scrollbar work. It will always wrap off the text and put it on another line instead of enable the scrollbar. See example 

#!/perl/bin/perl


use Tk;

#
sel_report();
#
######################  Main Graphical GUI activation
sub sel_report{
    my $wjob = MainWindow->new;
    $wjob->title("GRAPHICAL COMPARE");
    $testo=$wjob->Text( -borderwidth =>2, -relief => 'solid', -height 
+=> 40, -width => 120)->pack();
    $ugo = $testo->Scrolled("Text")->pack();
    open (FILE, "c:/tmp/compare_results.txt") || die "cazzo fai";
    while(<FILE>){
        $ugo->insert('end', "Page 1

                        Compare results    ( UNIT ARE IN MM )

  X Position    Y Position   JOB Name       Step1        Step2        
+     Ref.Layer

    }
    close (FILE);

Re: Using scrollbar in combination with Text and pack function
by juo (Curate) on May 27, 2002 at 12:32 UTC

    I have found how to do it. It's just a little bit more of code. The scrollbars have to get linked to the text widget and wrap mode should be set to none. 

    #!/perl/bin/perl


use Tk;

#
sel_report();
#
######################  Main Graphical GUI activation
sub sel_report{

    my $mw = MainWindow->new;
    $mw->title("GRAPHICAL COMPARE");
    $wjob = $mw->Frame()->pack(-side => 'top', expand => 1, -fill => '
+both');    
    $scrollbarver = $wjob->Scrollbar()->pack(-side => 'left', -fill =>
+ 'both');
    $scrollbarhor = $wjob->Scrollbar(-orient => 'horizontal')->pack(-s
+ide => 'bottom', -fill => 'both');

    $testo=$wjob->Text( -borderwidth =>2, -relief => 'solid', -height 
+=> 40, -width => 100 , -wrap => 'none' , -yscrollcommand => ['set' =>
+ $scrollbarver], -xscrollcommand => ['set' => $scrollbarhor]);
    #$testo=>Scrolled("Text", - scrollbars => 'se')->pack();

    
    $scrollbarver->configure(-command => ['yview' , $testo]);
    $scrollbarhor->configure(-command => ['xview' , $testo]);

    $scrollbarver->pack(-side => 'right', -fill => 'y');
    $scrollbarhor->pack(-side => 'bottom', -fill => 'x');
    $testo->pack(-side => 'bottom', fill => 'both', -expand =>1);

        $testo->insert('end', Page 1

                        Compare results    ( UNIT ARE IN MM )
