|
## IWC + JSON Example
|
|
Here, I will give a short overview on how to use the IwcJson Framework in Role-SDK widgets.
|
|
First you have to include the following libraries in your widget file:
|
|
```
|
|
<script src="http://open-app.googlecode.com/files/openapp.js"></script>
|
|
<script src="http://dbis.rwth-aachen.de/gadgets/iwc/lib/iwc.js"></script>
|
|
<script src="http://dbis.rwth-aachen.de/~jahns/role-widgets/widgetbundles/libraries/DUIClient.js"></script>
|
|
<script src="../../build/browser/Frameworks/JsonFramework.min.js"></script>
|
|
<script src="../../build/browser/Connectors/IwcConnector.min.js"></script>
|
|
<script src="./index.js"></script>
|
|
```
|
|
A working widget implementation is [IwcJson.xml](./IwcJson.xml) and the js-file is [index.js](./index.js)
|
|
*/
|
|
function init(){
|
|
Y.createIwcConnector(function(Connector, user_id){
|
|
/**
|
|
yatta is the shared json object. If you change something on this object,
|
|
it will be instantly shared with all the other collaborators.
|
|
*/
|
|
yatta = new Y.JsonYatta(user_id, Connector);
|
|
|
|
/**
|
|
You may want to get the created DUI client (you must not create two DUI/IWC clients!!),
|
|
or set an IwcHandler.
|
|
*/
|
|
var duiclient = yatta.getConnector().duiclient;
|
|
function iwcHandler (intent) {
|
|
console.log("Received intent: "+JSON.stringify(intent));
|
|
}
|
|
yatta.getConnector().setIwcHandler(iwcHandler);
|
|
|
|
/**
|
|
Add a integer-property like this
|
|
*/
|
|
yatta.val('x', 7);
|
|
|
|
/**
|
|
Get the value of property x like this
|
|
*/
|
|
console.log(yatta.val('x') === 7); // true
|
|
|
|
/**
|
|
A string property can be either mutable or immutable.
|
|
*/
|
|
yatta.val('mutable_string', "text", "mutable");
|
|
yatta.val('immutable_string', "text", "immutable");
|
|
|
|
console.log(yatta.val('immutable_string') === "text"); // true
|
|
yatta.val('mutable_string').insertText(2,"XXX"); // position, string
|
|
yatta.val('mutable_string').deleteText(0,1); // position, deletion length
|
|
console.log(yatta.val('mutable_string').val() === "eXXXxt"); // true
|
|
|
|
})
|
|
}
