A generic dialog window, which supports result values.
The GenericDialog widget class is suitable to create dialog windows
which need to check for certain dialog results in an easy
way. Specific result values can be bound to the buttons of the
dialog and will be emitted upon clicking the buttons.
The creation of the GenericDialog is a bit different from other
widgets. Besides the title, it receives two lists for the buttons to
display and the results they have to send. Both lists need to have
the same length.
dialog = GenericDialog ('Test', [Button ('OK'), Button ('Cancel')],
[DLGRESULT_OK, DLGRESULT_CANCEL])
The index of the result values need to match the index of the
button, that should emit them. Of course the buttons can be changed
at runtime programmatically with the set_buttons() method, which is
similar to the constructor.
dialog.set_buttons ([Button ('Close'), Button ('ClickMe')],
[DLGRESULT_CLOSE, DLGRESULT_USER])
The result values to set must match a valid value from the
DLGRESULT_TYPES tuple.
Given the above set_buttons() example, a callback for the
SIG_DIALOGRESPONSE signal will receive either the DLGRESULT_CLOSE or
DLGRESULT_USER value upon which certain actions can take place.

The GenericDialog is separated in several frames, to which user
content can be added. The main frame, which holds anything else, can
be accessed through the 'main' attribute. While it is possible to
change most of its attributes without unwanted side effects, its
children should not be modifed or deleted to prevent misbehaviour of
the dialog.
dialog.main.spacing = 10
The second frame, which is usually the most interesting is the
content frame, packed into the main frame. It can be accessed
through the 'content' attribute and should (only) be used to add own
widgets. Those can be deleted and modified, too.
