Re: need a popup gui stdin

For creating GUI application first refer : Perl/Tk or cpan perl tk A sample code :

Use Tk;
my $mw = new MainWindow(-background=>'#3B5998');
my $frm_name = $mw -> Frame();
my $lab = $frm_name -> Label(-text=>"Enter your feedback");
my $ent = $frm_name -> Entry();
my $but = $mw -> Button(-text=>"Submit", -command =>\&push_button);
$lab -> grid(-row=>2,-column=>1);
$ent -> grid(-row=>2,-column=>2);
$frm -> grid(-row=>2,-column=>1,-columnspan=>2);
$but -> grid(-row=>4,-column=>1,-columnspan=>2);
MainLoop;

sub push_button {
my $txt=$ent -> get();
$mw -> messageBox(-type=>"ok", -message=>"You printed this $txt");
}

Updated my code, it is just a sample program and also don't forget to install TK and dependencies related with it.

Updated my code, it is just a sample program... The updated code still won't work. The statement `Use Tk;` is still wrong and the `$frm` scalar is nowhere defined or, more importantly, initialized. See the statement `$frm -> grid(-row=>2,-column=>1,-columnspan=>2);` Even sample programs should actually work, especially when they are being given to beginners. Also, can you make the program run with strictures and warnings enabled? `use warnings;` `use strict;`	[reply] [d/l] [select]

use warnings;
