Hi Maxim, Thank you for highlighting this important point(About Synchronizing drawing with all the viewers of Whiteboard) which I should know. I will point out the things which I understood for verification,
- Whiteboard component have functionalities like draw Circle ,Line etc. - There should be methods like onCircleDraw/onLineDraw etc. which will be executed after each particular event happens. - The user of the Whiteboard component can use these functions for a task by overriding them or can leave them. - Here in this particular scenario in OpenMeetings, we have to implement a logic in these functions to sync drawing with viewers. I am bit confused on the last point. What can be useful technologies to do this drawing synchronization? Is there a implementation in current Flash/Openlaszlo, which I can refer ? I am new to that area and have no clue. Thank You! Regards Andun S.L.
