Hello,

I am not sure you need ALL of the list above, but it will not hurt and it is proven to work. So,
- set the min-, max-, and preferred- size to required dimension for Figure
- set Node's resize constraint to Direction.NONE
- create the DefaultSize facet with the desired size inside the corresponding Node

Hi Lamia,

what do you mean with fix size? Do you want to disable resizing of a figure?

This can be done by installing a NonResizableEditPolicy to your figures edit part.

Unfortunatelly, this does not prevent the user to set a custom size during creation of the element. To disable this you can override the getCreateElementAndViewCommand method in the parents CreationEditPolicy like this:

@Override
protected Command getCreateElementAndViewCommand(
	CreateViewAndElementRequest request) {
String semanticHint = request.getViewAndElementDescriptor().getSemanticHint();
if (semanticHint == MyFigure)){
   request.setSize(new Dimension(-1, -1));
}
return super.getCreateElementAndViewCommand(request);
}

Maybe there is a better way to prevent resizing on creation?

Regards,
Andreas
