>>>>>>>>>>>>>>> >>>>>>>>>>> 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!
