About Gtk2_EntryDialog
Gtk2_EntryDialog provides a dialog with a message
and one single text input field, and some buttons like OK and Cancel.
The class tries to make it as easy as possible to get the text
from the user with only a few lines of code, while keeping the full
power of the GtkDialog class.
The most easy way to retrieve the text with one line of code is
using the
get()
static method.
