JS Editor Integration
---------------------
## Running the JS only version
Start by creating the .zip file:
`mvn assembly:assembly -Dmaven.test.skip=true`
To test the javascript frontend you then do:
ruby -rwebrick -e 'WEBrick::HTTPServer.new(:Port=>8000,:DocumentRoot=>".").start'
Now open a browser using the URL http://localhost:8000/wise-editor/src/main/webapp/
### Attaching drag and drop events.
1) Support for dragging TextNodes:
The following code is an example of how to add attach to the div dragImageNode the support for node dragging.
$("dragTextNode").addEvent('mousedown', function(event) {
event.preventDefault();
// Create a image node ...
var mindmap = designer.getMindmap();
var node = mindmap.createNode();
node.setText("Node Text !!!!");
node.setMetadata("{'media':'test'}");
node.setShapeType(mindplot.model.TopicShape.RECTANGLE);
// Add link ...
var link = node.createFeature(mindplot.TopicFeature.Link.id, {url:"http://www.wisemapping.com"});
node.addFeature(link);
// Add Note ...
var note = node.createFeature(mindplot.TopicFeature.Note.id, {text:"This is a note"});
node.addFeature(note);
designer.addDraggedNode(event, node);
});
In the example, a new node is created with text "Node Text !!!!" and a note and a link associated to it when the user drop the node. Something to pay attention is the node.setMetadata("{}"), this delegated will be persisted during the serialization. Here you can store all the data you need.
2) Support for dragging Images: Similar to the point 1,drag support is registered to the div dragImageNode.
$("dragImageNode").addEvent('mousedown', function(event) {
event.preventDefault();
// Create a image node ...
var mindmap = designer.getMindmap();
var node = mindmap.createNode();
node.setImageSize(80, 43);
node.setMetadata("{'media':'video,'url':'http://www.youtube.com/watch?v=P3FrXftyuzw&feature=g-vrec&context=G2b4ab69RVAAAAAAAAAA'}");
node.setImageUrl("images/logo-small.png");
node.setShapeType(mindplot.model.TopicShape.IMAGE);
designer.addDraggedNode(event, node);
});
The node.setShapeType(mindplot.model.TopicShape.IMAGE) defines a image node. This makes mandatory the set of setImageUrl and setImageSize properties in the node.
3) An event registration mechanism for Image nodes edit events: The next snipped show how to register a custom edition handler.
designer.addEvent("editnode", function(event) {
var node = event.model;
alert("Node Id:" + node.getId());
alert("Node Metadata:" + node.getMetadata());
alert("Is Read Only:" + event.readOnly);
} });
