Re: Setting value in Tk -textvariable

[Chmrr]

Tk's not the one complaining at you; perl is complaining that you're not doing what you think you're doing. If it's saying that it can't use a string as a hash reference, that means that $move isn't a hash reference, it's a string. Somewhere along the ways, you've gotten confused as to what's in what variable. I'd suggest a proper application of Data::Dumper to the variables in question to figure out what's going on.

Here's a crude and fast example of setting a label's value to something in a hash reference:

use Tk;
my $main = tkinit;     
my $value = "Foo!";
my $href = {bar=>baz};    
$main->Label(-textvariable=>\$value)->pack;
$main->after(5000,sub{$value=$$href{bar}; $main->update;});
$main->MainLoop();

perl -pe '"I lo*`+$^X$\"$]!$/"=~m%(.*)%s;$_=$1;y^`+*^e v^#$&V"+@( NO CARRIER'
