Wt

Hi Koen, Wim,

I have code I am trying to port to Wt and am having trouble with the drag and drop functionality. I want the drag and drop to happen on the client side, and my current Javascript code is something like this:

var dragsource=new Ext.dd.DragSource("sourceDiv", {ddGroup:'TreeDD',dragData:{name: "PNG1"}});

var droptarget=new Ext.dd.DropTarget("CenterDiv",{ddGroup:'TreeDD'});

droptarget.notifyDrop=function(dd, e, data)

{

if(data.name)

{

Some logic here...;

return true;

}

}

The sourceDiv and CenterDiv are

elements which have random id in Wt, so the droptarget.notifyDrop should be defined after the elements are created (I guess). But I can't get this to work. No matter how I add the notifydrop function (using doJavaScript, declareJavaScriptFunction or simply adding it as string in the createDomElement) I cannot get this to work. In fact nothing appears on the screen if I try to define this function.

Do you know what is going on? I really have to have the drag drop happen on the client machine, and not come back to the server. Is there any way I can accomplish this with Wt?

Thanks
