Hi.

Is that possible to get the mousePosition from movecontext instead of element new position X,Y.

I need the position in the allowed container calculated in canMoveshape, without that I know that the mouse is in the right place, but I don't know which place is that.

Thanks

Rui,

you can get the current mouse position from the diagram editor, from within
your move feature with something like ((DiagramEditor)
getDiagramEditor()).getMouseLocation().

Not sure if that is sufficient.

Michael

I saw that. But it returns coordinates relative to diagram.

I need the coordinates relative to the container. Unless there is some converter. I think it is not possible to do the calculations, because I would need the mouse coordinates at the begining of the drag.

A is context (xy)

For those who are interested. I solved my problem using only absolute location.

In move context I get global mouse position instead of getX and getY ( which is the left corner of the shape), as below:

DiagramEditor de = (DiagramEditor)getDiagramEditor();
Point location = de.getMouseLocation();

And I do my calculations converting the position of shapes I'm interested to the absolute system:
GraphitiUi.getUiLayoutService().getLocationRelativeToDiagram((Shape)iGroupGA.getPictogramElement());

Thanks .
