Why hello there.
I have been set an assignment to make a hangman game with perl and tk.
All is good, however when the user enters a letter and presses the enter key, nothing happens, they need to click on a button to get stuff to happen.
Here is some code
| Code: |
...
# This is a text-userinput field
my $entryword = $main->Entry(
# width is in characters, not pixel
-width => 20)->place( -x => 440, -y => 175);
...
y $inputButton = $main->Button(-text => 'Take input', -state => "disabled",
-command => sub{sayhello()}
)->place(-x => 440, -y => 355 );
...
|
I want 'sayhello' to be run when the user has inputted a letter and presses enter.
Even better, the user can only input one letter and 'sayhello' is automatically run when then input one letter...
How would I go about doing this?
Thanks

Figured out the enter key bit.
| Code: |
$main -> bind('<Return>', sub {sayhello()});
|
so simple.

Perl's syntax makes my eyes bleed.
Oh sorry, thought this was a Python thread
