Positioning a Label at the end (beginning) of a connection figure ... [message #53380]

Hi there,

i want to add a Label at the end of a (decorated) connection which
should represent the target (source) cardinality of the connection. What
could i add to my PolyLine Connection in my .gmfgraph file?

One thing i tried was a BorderLayout as child from the Connection and a
FigureRef also as child. Then the FigureRef gets the BorderLayoutData
(END). But this didn't work out:

<figures xsi:type="gmfgraph:PolylineConnection"
referencingElements="CompositionLink"
name="SolidLineFilledDiamond" targetDecoration="FilledDiamond">
<layout xsi:type="gmfgraph:BorderLayout"/>
<children xsi:type="gmfgraph:FigureRef"
figure="EjbRelationTargetCardinalityFigure">
<layoutData xsi:type="gmfgraph:BorderLayoutData"
alignment="END"/>
</children>
</figures>

Is there a build in possibility to solve this? Or must i implement an
own Layout?

regards
Jens Krause

In gmfgraph model add AlignmentFacet to the DiagramLabel. In this facet
you may select appropriate label alignment relative to the link.

Thanks a lot, that is a good step in the right direction :).

But the result is not quite satisfying me ... Could i influence the
position where at the beginning or end of the connection appears?
Perhaps with a LocationPoint or so?

Well, opened eyes are often useful ;). Found the "Label Offset Facet" :).

Thanks again
