clearing text box elements in perl tk

Question

I am building a GUI in Perl tk and I have made a reset button which is supposed to clear elements of a text box:

use Tk;
use Tk::Text ;
............
sub reset9 {
    $txt2-> delete('1.0','end');
}

This is giving an error saying it cannot call method Delete on an undefined value. I have checked for all syntax errors and I am using Strawberry Perl for Windows.

Answer 1

You may try : $txt2-> delete('0.0','end');

Answer 2

Your subroutine does not know what $txt2 is. If $txt2 was defined inside another subroutine add the word "our" before it (instead of using my).

i.e.

our $txt2 = ...

That should do the trick for you
