Hi Maxim,
Need your assistance in figuring out the whitboard synchronization logic.
Currently what we have is this.
- WhiteboardBehaviour which can be applied in this format,
WhiteboardBehavior whiteboardBehavior=new WhiteboardBehavior("whiteboard");
- When this is added to a page, all the whiteboard elements will be
added to a Map. Each Creation,Update will effect on this collection
- Using this kind of a JavaScript, we can add elements to a whiteboard.
elementCollection=whiteboard.getMainCollection();
elementCollection.acceptJsonStr('ChangedElementJSON');
- Using this kind of a JavaScript, we can load a whiteboard using JSON
string of all the elements
elementCollection=whiteboard.getMainCollection();
elementCollection.acceptJsonStr('elementLisyJSON');
In the current test application, I use two buttons to add elements to
whitebord and load whitebord from given JSON string.
My question is what is the best way to implement Whiteboard Synchronization
using these code in Wicket? I planned is this kind of approach,
- 1st person open the Whiteboard
- He is draws some elements and the element map in the
WhiteboardBehaviour get update
- 2nd person comes and open the whiteboard. The behavior found that
element map(This should be a static collection) is not empty. Thus load the
content of whiteboard using the element map. 3rd, 4th happens like that
- When one person do a change in the whiteboard, element map wll be
updated. Meanwhile all the other have to be pushed with the new change
- There whiteboards get update with new change
If this is OK how can we push updates to clients form wicket server to
achieve 4th step? If you want to have a look a the current code, all are in
github.
Thanks!
