Re: Refresh data ina entry widget

[zentara]

Whenever you want a refresh on a time period in Tk, you probably want a timer.

$mw->repeat(1000, \&status_bank);

sub status_bank{
   ......... do your extraction from file

   $mw->update;
   
}

If you have alot of banks and entries, put them all in a hash, and loop thru them, like this pseudocode:

my %box_banamex;

$box_banamex{$bank}{'entry'} = $upperframe->Entry(.........
                -textvariable => \$box_banamex{$bank}{'status'},
 

foreach my $bank (keys %box_banamex){
      #read each value from file
     $box_banamex{$bank}{'status'} = whatever from file parsing;
    $box_banamex{$bank}{'entry'}->update;
}

Hi
I am trying really trying but can you please elaborate more on the pseudocode because i dont get it, please?

Pseudocode means "this is a non-functional shorthand view" of the steps you would need to take to write working code. I don't particularly like being asked to write code for someone who is getting paid for it. So here is a general purpose example, if you can't figure out the rest, you should read some books.

#!/usr/bin/perl
use warnings;
use strict;
use Tk;

my $mw = MainWindow->new();

my %data;

foreach my $bank qw(aa bb cc dd){
  
  
  $data{$bank}{'frame'} = $mw->Frame->pack();

  $data{$bank}{'bankname'} = $bank;
  $data{$bank}{'status'} = 'offline';

  $data{$bank}{'label'} = $data{$bank}{'frame'}->Label(
      -textvariable => \$data{$bank}{'bankname'})->pack(-side=>'left')
+;
  
  $data{$bank}{'entry'} = $data{$bank}{'frame'}->Entry(
      -textvariable => \$data{$bank}{'status'},
      -bg => 'white',
      )->pack(-side=>'right');
}


$mw->repeat(2000, sub{
    foreach my $bank (keys %data){
            
            my $rand = rand 10;
            if ($rand > 5){
                  $data{$bank}{'status'} = 'online';
                  $data{$bank}{'entry'}->configure(-fg => 'red');
                 }else{
                   $data{$bank}{'status'} = 'offline';
                   $data{$bank}{'entry'}->configure(-fg => 'black');
                 }
    
        }
});

MainLoop;
