Save functions missing?

[ghost]

Hi There

I would like to use this whiteboard and whilst I have it working it seems to be missing the save, undo features shown

https://github.com/wicketstuff/core/wiki/Whiteboard

Can you tell me how I can add these in?

THanks

Hi Jason,

You can easily add buttons to toolbar using 
whiteboard.addTool( id , groupId , actions , order , label) method:

whiteboard.addTool('save', 'tools', {action: actionFunction}, 10, 'Save')

You can place new buttons to the 'tools' group (where zoom-in, zoom-out and so on already placed) or create new group using whiteboard.addGroup ( id , order , label ) method.

For save operation action function can look like :

actionFunction = function(board){
  var boardData =  board.collections.main. jsonCode();
  // here you can save the data where you want
  // to restore you should call board .collections.main.parseJson(baordData);
}

For undo it's a bit more painful. You should add listener for collections.main.onChange event, save board data somewhere and restore it when user click undo.

Regards,
Andrey

Hi Andrey

Thanks for the reply. I have located an uncomressed later version of the whiteboard
https://github.com/wicketstuff/core/tree/master/jdk-1.7-parent/whiteboard-parent/whiteboard/src/main/resources/org/wicketstuff/whiteboard/resource

This has the icon images etc for save undo and yet it doesn’t have the code for the save file. Do you know why that was not included?

Also have you any example code for saving within the function?

Thanks Again,

Jason

Wicket integration for whiteboard was made by Andun Gunawardana and these functionality (saving, undo) was added be him. Unfortunately I don't know the details of this. I made only javascript library which doesn't work directly with any external components.

Also have you any example code for saving within the function?
I don't have such code. It depends on where you want to save the data. Whiteboard works inside browser and standard sandbox policy doesn't allow to write to local file directly. So you should either send data to server (using Ajax, Websocket and so on) or use FileSystem API. As example whiteboard has special shortcut (Ctrl+J) which activate window where you can see the text data. It is possible to copy and past it there.
