Hi esteem monks,
I wanna read content of file to text widget. It appends a new line every 3 sec. Below is my code:
use strict;
use warnings;
use Tk;
my $mw = MainWindow->new();
my $st = $mw->Scrolled("Text",-scrollbars => "eo")->pack();
$st->repeat(3000,\&list);
MainLoop;
sub list {
my $fh;
open ($fh, "<D:\\perl_script\\sqlnet.log") or die "error!!$!\n";
while (<$fh>) {
$st->insert("end", $_);
}
close ($fh);
}
But it doesn't work well. Every 3 sec, text widget showed a page, not a line, furthermore, the slider doesn't jump to
the end of the text, so you have to drag it to see new added contents.
any suggestions?
I am trying to improve my English skills, if you see a mistake please feel free to reply or /msg me a correction
