This is not a criticism, this is just what was produced with available resources - which is great. However if I don't (a) fully understand why it was done that way and (b) get consensus on modifications, I may end up making changes that are incorrect and unwanted.

True some of the properties are device specific, but then some of the device properties not in features are also device specific ..

 Just not good analize of a (web)camera done by developer?
 You can only do this on a camera you have in first place.
 
 But its good he did make it and available to play with it
 so we can have fun with it :)

Where did I say do not improve?
I have say we can have fun with it.
That is just what you are doing and try to improve it.
That is not wrong, that is good and improve the support
in Gambas.

And that mess was more or less the source for Daniel available.
It was for him only to get his camera working with Gambas.

Of course it is a good habbit to try the right thing.


It's just that I see the (wed)camera/tvcard as collection of class 
parts for audio, video and control (and audio/video filters)
together with a class/module/form(whatever) for the user interface.

Just the same as gb.qt, gb.qt.dialog, gb.qt.something etc.

Sorry if you did see it as a attack from me, it's not mean that way.
In fact I'm curious what and how you cook for us. :) :)


Best regards,
