>>>>>>>>>>>>>>>> >>>>>>>>>>> Hi Andrey,
>>>>>>>>>>>>>>>> >>>>>>>>>>>
>>>>>>>>>>>>>>>> >>>>>>>>>>> I am moving in to this new thread to discuss
>>>>>>>>>>>>>>>> about the clarifications,
>>>>>>>>>>>>>>>> >>>>>>>>>>> improvements and integration of your Whiteboard
>>>>>>>>>>>>>>>> to wicket. I have looked at
>>>>>>>>>>>>>>>> >>>>>>>>>>> your code which can be found
>>>>>>>>>>>>>>>> https://github.com/bay73/whiteboard . I
>>>>>>>>>>>>>>>> >>>>>>>>>>> have following questions,
>>>>>>>>>>>>>>>> >>>>>>>>>>>
>>>>>>>>>>>>>>>> >>>>>>>>>>> - In Wicket, I want map Whiteboard
>>>>>>>>>>>>>>>> Elements(Rectangle, Circle,
>>>>>>>>>>>>>>>> >>>>>>>>>>> Text, etc.) to Java objects.
>>>>>>>>>>>>>>>> >>>>>>>>>>> - Thus we can send those object to all the
>>>>>>>>>>>>>>>> Whiteboard viewers.
>>>>>>>>>>>>>>>> >>>>>>>>>>> - Using these objects there Whiteboards will
>>>>>>>>>>>>>>>> be updated.
>>>>>>>>>>>>>>>> >>>>>>>>>>> - To do that, can I get some data from your
>>>>>>>>>>>>>>>> code? which can be
>>>>>>>>>>>>>>>> >>>>>>>>>>> later used to create elements. I saw there
>>>>>>>>>>>>>>>> is a serialization methods and
>>>>>>>>>>>>>>>> >>>>>>>>>>> deserilization method in base.js. If we can
>>>>>>>>>>>>>>>> extend that mechanism to give
>>>>>>>>>>>>>>>> >>>>>>>>>>> some data when element is drawn or edited as
>>>>>>>>>>>>>>>> an event, I can use them to
>>>>>>>>>>>>>>>> >>>>>>>>>>> create Java objects.
>>>>>>>>>>>>>>>> >>>>>>>>>>> - Also there should be a mechanism to draw
>>>>>>>>>>>>>>>> elements on your
>>>>>>>>>>>>>>>> >>>>>>>>>>> Whiteboard by passing those data.
>>>>>>>>>>>>>>>> >>>>>>>>>>>
>>>>>>>>>>>>>>>> >>>>>>>>>>> Can we do these things?
>>>>>>>>>>>>>>>> >>>>>>>>>>>
>>>>>>>>>>>>>>>> >>>>>>>>>>> Thanks!
