Dendrogram collapse/expand sub-tree

[Nemanja Vukosavljevic]

Hi to all!

First I want to thank all the people involved in this project who made it possible to use this awesome tool :)

I've implemented my own example of a dendrogram using Protovis-GWT and I have a need to collapse/expand a sub-tree by clicking on a specific node. Following the code in DendrogramExample I tried to add the event PV.Event.MOUSEDOWN on the line 61 of the class but I don't have an idea how to handle the Event.

Any advice would be helpful. Thanks in advance.

Cheers

You can registering a PVEventHandler to handle MOUSEDOWN:

}).event(PV.Event.MOUSEDOWN, new PVEventHandler() {
public void onEvent(Event e, String pvEventType, JsArgs args) {
// your code here
}
}

Thanks for the response. In the end I did the similar thing but with registering PVEventHandler to handle DOUBLE_CLICK similar to the Force Toggle Test.
