The gadflyDatabase module works on introspection, so you don't need to 
write any code at all. It automatically iterates through every field in 
the Document (database result set) and if it can find a corresponding 
field in the View (PythonCard background) it stuffs one into the other.

In simple terms, a quick modification of the gadflyDatabase sample 
should just involve editing the resource file (gadflyDatabase.rsrc.py) 
and adding another component;

{'type':'Spinner',
     'name':'Id',
     'position':(<x>, <y>),
     },

Where <x> and <y> are the co-ordinates of the position you'd like to see 
the widget appear.

The only restriction is that the type of your widget must either be a 
'Spinner' or a 'Slider'. If you want to render it another way you'll 
need to edit the gadflyDatabase.py module, if you get that far post 
another message to the list and I'll try and help.

Regards,
Andy
