I have added an external design label to a node (N). The node N
is affixed to the side of its parent node (PN).
I want the label to be moveable freely. But GMF generates
the label to be affixed to the side of node N, even though I have set
the property "Affixed Parent Side" of the diagram label in .gmfgraph
to NONE.
How can I turn this off and allow to move the label freely?
Thanks so much in advance!!!

There is a way to get this done, by modifying the code. I don't know, if
this should be done like this, but it seems to work:
In the edit part, search for
protected EditPolicy createChildEditPolicy(EditPart child) {
if (child instanceof IBorderItemEditPart) {
....
There, just don't install BorderItemSelectionEditPolicy for your label
edit part. Now, you're able to drag the label around. But
BorderItemLocator still forces your label to stick at the parent. So
you'll need to override BorderItemLocator#locateOnParent(Point
suggestedLocation,int suggestedSide, IFigure borderItem), in a way, it
returns the drag position. Or write your own locator. For example:
private Point locateOnParent(Point suggestedLocation, int suggestedSide,
IFigure borderItem) {
return suggestedLocation;
}
Maybe there is a more sophisticated way... I don't know.
regards
