So I have a tk label which looks something like this:
$frame->Label(
-textvariable => \$value
)->pack();
Then later I try to set this variable $value to a referenced hash value. But if I make the assignment directly Tk gives me an error saying it can't use a "string" as a "hash ref". So instead i use this snippet of code that works:
my $value_buffer = $$move{'value'};
$value = $value_buffer;
assuming
$move is a reference to a hash with key 'value': how do i just assign
$value directly in one line?
thanks a lot
