Problem Suppose you have setup a dialog box similar to the example How to setup a dialog box - Part 2 - simple yes no dialog?.
Instead of returning 100 and 200, you would like to return 'Yes' and 'No' respectively (i.e. non-integer response IDs) for the buttons as shown below:
Solution If you use the method GtkDialog::response() to exit the dialog, you will find that the response ID has to be an integer. You cannot return a response with a non-integer response.
To return a non-integer response, we have to set up the dialog manually.

What's new here:
- Create the Yes button with a response ID of 'Yes'.
- Create the No button with a response ID of 'No'.
- Store the response ID in the global variable
$response.
- Destroy the dialog.
- Echo the response in the GtkEntry, which is stored in the global variable
$response_str.
