Hi All,
I have to create files based on the ext1 - ext2 and write few lines
of code there. The created file should have to option like like update and
save so that user can edit the file in future.
For this I choose the Radiobatton option of Perl/Tk. Here I am doing a very
silly mistake, and it is just due to little knowlege towards Perl/TK
(started learning Perl/TK for 2 days).
So Request you to let me know where I am doing the mistake.
It will great help, if you help me to overcome this issue.
#!/usr/bin/perl -w
use Tk;
use strict;
our ($filename);
$filename = "DMM";
my $mw = MainWindow -> new;
my $rb_value = "red";
$mw -> configure( -background => $rb_value);
my $val;
foreach ( qw ( ext1 ext2 ext3) ) {
$mw -> Radiobutton ( -text => $_,
-value => $_,
-variable => \$val,
-command => \&set_bg) -> pack (-side => 'left');
}
MainLoop;
sub set_bg {
my $Data = "Hello World";
print " Selcted CPU is : $val\n";
#$mw -> configure ( - background => $rb_value);
$mw -> configure ( -textvariable => $rb_value);
print " File name is : $filename\n";
if ( $rb_value eq "ext1" ) {
$filename = $filename . "\_" . $rb_value;
print " Edited name is : $filename \n";
open ( FILE, $filename ) or die " Can't open the $filename $!";
print FILE $Data;
}
}
/Perl/GUI>perl Radio.pl
