Hi Michael,
this is very simple (but not very well documented): In the GMF-Map,
define these ports as child elements to the Widget, but do not assign a
compartment. As a result, the ports will be positioned like external
labels, i.e. movable around the parent figure. I do not know how to
assign them a fixed positon and how to make them not moveable, but I'm
sure you'll figure this out. Some settings can be done in the parent
edit part's addFixedChild method, e.g. [1] for setting the prefferred
positon and for moving the ports a bit inwards of the figure,
overlapping its border. Further, these is (or was?) a bug when deleting
one of the ports, resulting in multiple visual elements being removed.
to fix this, add this [2] to the parent edit part.
Hope this helps,
Tobias
[1]
BorderItemLocator locator = new
BorderItemLocator(getMainFigure(),PositionConstants.SOUTH);
locator.setBorderItemOffset(new Dimension(20, 20));
getBorderedFigure().getBorderItemContainer().add(childEditPa rt.getFigure(),locator);
[2]
protected void handleNotificationEvent(Notification notification) {
super.handleNotificationEvent(notification);
if (notification.getEventType() == Notification.REMOVE) {
handleMajorSemanticChange();
}
}
