Widget name is used because the file continues to be a valid glade file
and can be edited through glade.
It would be nice to have somewhere to enter arbitrary properties and
values. Then it would be added as
<property name="myprop">myval</property>
in the glade XML file.

Yes, this is an alternative. But don't forget that autoglade "is" the
application (or the module imported in some cases), not to be run as
part of the designer.
i.e: $ autoglade myapp.glade
Am I missing something ?

Yep, would be nice, but much harder to implement I think.
Currently, autoglade can invoke any method almost with any arbitrary
list of parameters (widget:auto:method:params).

Very interesting idea indeed.

autoglade target, at this stage, is to simplify (or to eliminate in some
cases) the development of simple applications, mainly to give a command
line tool a GUI.
One of the most representative examples is described in the tutorial
(rdc, a GUI for rdesktop).
In about 100 lines of bash scripting, plus the glade definition plus
autoglade you have a "real" application comparable in functionality with
Microsoft's client or tsclient (~ 5K lines of C code).
Any ideas are welcome.


Again, thanks for your comments.
