Hallo everyone,

I am a german student developing a gmf-prototyp for an mashup-concept.

What I want to realize:
______[Action1]__
| |
| Widget_A |
|_________________|
[Action2]
^
|
|
______[Event1]__
| |
| Widget_B |
|_________________|
[Action3]

I habe several widgets(normal boxes may be with a picture)
These widgets "own" actions and events. When I choose one of them over the
context-menu (allready established :-) ) a docked, labeled box should
appear.
This docked box has to be hanging on the widget (moving with it).

How can I achieve these "docking boxes" ???

I habe heard a lot about "bordered Items" and "ports". I have tryed to
realize them with the border-layout, but I even could not get an simple
border-layout working. Are they made by "gmf-modeling" or only by coding ?

May be there are some more detailed diskriptions with model-examples in
the web? or some tutorials?

Any help greatly appreciated!!!
Thanks!

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();
}
}
