Hello all,
I try to do a node that it cannot move because a I implement the location
for this.
I have seen another post that ask for this problem but it is not answered.
Thanks.

Hi,
you could override the LayoutEditPolicy in your DiagramEditPart like this:
installEditPolicy(EditPolicy.LAYOUT_ROLE, new XYLayoutEditPolicy(){
protected Command getMoveChildrenCommand(Request request) {
boolean containsUnmoveable = false;
for(Object o : ((ChangeBoundsRequest)request).getEditParts())
{
if (o instanceof MyUnmoveableEditPart)
containsUnmoveable = true;
break;
}
return containsUnmoveable?UnexecutableCommand.INSTANCE:
getResizeChildrenCommand((ChangeBoundsRequest)request);
}
});

Oh... wait a minute.
In your EditPart, you should find a methos like this:
public EditPolicy getPrimaryDragEditPolicy() {
EditPolicy result = super.getPrimaryDragEditPolicy();
if (result instanceof ResizableEditPolicy) {
ResizableEditPolicy ep = (ResizableEditPolicy) result;
ep.setResizeDirections(PositionConstants.NONE);
//dont't move me
ep.setDragAllowed(false);
}
return result;
}
Adding the line under the comment should be prefered, I think. So, you
don't have to override DiagramEditPart's LayoutEditPolicy.

Yes, I add this piece of code:
protected Command getMoveChildrenCommand(Request request) {
boolean containsUnmoveable = false;
for(Object o : ((ChangeBoundsRequest)request).getEditParts())
{
if (o instanceof MyUnmoveableEditPart)
containsUnmoveable = true;
break;
}
return containsUnmoveable?UnexecutableCommand.INSTANCE:
getResizeChildrenCommand((ChangeBoundsRequest)request);
}
to the method createLayoutEditPolicy(), that it contained one.
Thanks again.

I've implemented this method in the EditPart of a Node. It works, but my
problem is that the figure overlaps existing figures. The running the
setLocation method yields no effect.
How can I solve this?
