Hi,
I need to display small squares attached to the border of a parent
symbol, the same as the ports in UML. I've heard that setting the
side-affixed property of the Node element in the gmfgraph file could do
the job. I have spent a lot of time on this with no success. What should
I do to make it working?
Thanks in advance,
Kalin

Hello,
I have a big rectangle with a compartment and a small rectangle which
has to stick on the borders of the big parent rectangle. As soon as I
set the small rectangle's side-affixed parent to NSEW the big
rectangle's compartment disappears and I can hardly select and move the
big rectangle. In addition to that I can no longer add new small
rectangles - the mouse cursor is a "no" sign. I have the expected
behavior, but only for the previously added small rectangles. What could
be wrong?
Thanks,
Kalin

Hello again,
Adding a border didn't help. The reason was that the compartment figure
was not a child of the big rectangle in the .gmfgraph file and for some
reason was stretched too much. Now the compartment rectangle is a child
of the big rectangle and visually it is ok. Unfortunately now when I
insert the big rectangle in the canvas it is stuck in the upper left
corner of the canvas and cannot be moved, resized or even selected :-(

Hi,
I have created a separate example editor. Here is the situation:
* Without setting side-affixed property everything works fine
* If I set the side affixed property without a compartment everything
works fine
* If I add a compartment with a figure which is a child element of the
master rectangle, the appearance of the symbol is correct, but it is
attached at the upper left corner of the canvas and cannot be moved,
selected, also the whole canvas becomes unusable - no more elements can
be added, modified, etc..
* If I add a compartment with a figure which is not a child element of
the master rectangle, the canvas is editable, but I cannot add small
squares on the border of the master rectangle, because the compartment
figure is stretched and seems to overlap the border. In addition to that
the compartment is no longer collapsible, nevertheless the arrow shows
the opposite.
I cannot live without those compartments, so I desperately need to make
that working. Is there somewhere, anywhere any example on how to use
side-affixed borders of a symbol which has compartments? Attached is a
simple picture of what I want.
Thank you very much in advance!

protected NodeFigure createMainFigure() {
NodeFigure figure = new DefaultSizeNodeFigure(getMapMode().DPtoLP(40),
getMapMode().DPtoLP(40));
figure.setLayoutManager(new StackLayout());
contentPane = new BlockFigure();
figure.add(contentPane);
ConstrainedToolbarLayout layout = new ConstrainedToolbarLayout();
contentPane.setLayoutManager(layout);
return figure;
}
public IFigure getContentPane() {
if (contentPane != null) {
return contentPane;
}
return super.getContentPane();
}
/*
* our superclass messes this up, not returning the correct content pane
* (non-Javadoc)
*
* @see org.eclipse.gmf.runtime.diagram.ui.editparts.AbstractBordere dShapeEditPart#getContentPaneFor(org.eclipse.gmf.runtime.dia gram.ui.editparts.IGraphicalEditPart)
*/
protected IFigure getContentPaneFor(IGraphicalEditPart editPart) {
if (editPart instanceof IBorderItemEditPart) {
return getBorderedFigure().getBorderItemContainer();
} else {
return getContentPane();
}
}
I've got code that does that, but it hasn't been generated automatically
and it uses GMF 1, maybe Alex can say whether there have been API changes
in the runtime.
If you're interested I can send you some code you could compare to the
generated one to see where the problem is.
cheers,
vlad

Any exceptions in .log file or console? Can you add empty compartment first?
So, there will be "master rectangle" with child reference to "small rectangle"
(affixed) and empty compartment.

Looks like an incorrect configuration. Compartments are just a way to “visually
group” child elements of the node. This means, you can have master rectangle
with several child node references. In addition several compartments can
present in this “master rectangle”. Child nodes could be grouped and visualized
inside corresponding compartments by attaching them to the compartment element
in .gmfmap model. In other words, compartment can reference only child nodes
of it’s parent node.
Side-affixed node is a node located on the border of “master rectangle”.
This not should not be included into any compartments of the “master rectangle”.
AFAIK there should be an audit warning you about this constraint.

There should be a way to make it working. ;-) First you can try Vlad’s suggestions.
As a sample of elements located on border I can suggest you to have a look
on “org.eclipse.mdt.uml2.diagram.*” plugins. These plugins are created using
GMF and AFAIK side-affixed children are used there together with compartments
(with additional border in main figure).
