Question about Expand command in JNET

[former_member188498]

Hi,

Is was wondering if it's possible to dynamically add a set of nodes to existing graph in JNET?

For example we have an organizational chart and when a user double clicks on the node,

the node should expand and show only immediate child nodes.

Is something like this possible to achieve?

Regards,

Hi,

Technically speaking your requirement is very much posible.

What you have to do is subscribe to the double click event and then create of set of child nodes for the selected on and push the delta (if supported) to the client or the new xml to the client.

Hi,

I am trying to implement DoubleClick event for Network UI element but the problem is that the event handler

in Web Dynpro has only one parameter, like this:

public void onActionNodeDblClk(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

so I am unable to access the node which has been doubleclicked.

Shouldn't it have additional parameters, like Node etc?

Hi Ladislav

(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent)That is default parameter given by framework to us.

We have to define and we can define as much we want of any kind (IWDNode,IWDNodeElement ArrayList etc)

Ok follow

1. Create Action and Click next here put the name of parameter and select Browse --Select Java Native type

---Select Browse --Now write IWDNode

2. In the same way u can define different parameter also

3.Now u need to do the parameter mapping for this select the UI element --right click -- select parameter mapping --This UI have huge set of action so be clear that to whom action u want parameter mapping

for this case I think onNodeAdded is required(It has 4 parameter ).

Hope it will help you.
