Is there is a way to receive event when the node is moving (like MouseMove event) ?

Also I need a way to know when some shape is move upon another shape (like drag and drop)?

Thanks.

 

Hi Igor,

Although the NodeBoundsChanged event is not raised in the document for the shape being previewed, the same event NodeBoundsChanged is raised by the view event sink service when you drag the shape clone around. For speed optimizations you have to set the FireEvents property of the preview layer to true first.

Although the shape clone. which serves as preview is a different object than the shape being previewed, they will both have the same UniqueId. The following code captures the event and gets the original shape whose bounds are to be changed:

view.PreviewLayer.FireEvents = true;
view.EventSinkService.NodeBoundsChanged += new Nevron.Dom.NodeEventHandler(EventSinkService_NodeBoundsChanged);

void EventSinkService_NodeBoundsChanged(Nevron.Dom.NNodeEventArgs args)
{
NShape previewShape = args.Node as NShape;
if (previewShape == null)
return;

NShape orignalShape = (NShape)document.GetElementFromUniqueId(previewShape.UniqueId);
// previewShape.Bounds are the bounds of the preview
// orignalShape.Bounds are the current original shape bounds – they will be set to
// previewShape.Bounds once the user has finished moving the preview
}

Hope this helps – questions or comments – please feel free…

Best regards,
Ivo

How can I get the rotate value
