Label not centered [message #196884]

Hello,

I switched my GMF application to Eclipse 3.4 and by the way from GMF 2.1M2
to GMF 3.4.0.
Since then all editable Lables are not shown in the center of their parent
rectangle but in the upper left corner. I even did a new generation of the
diagram source. The source of the parent figure shows a createContents()
method with this line:

this.add(fFigureAktivitaetLabelFigure, BorderLayout.CENTER);

but it doesn't work as expected. What has been changed and what should I
do?

Any hints wellcome.

Manfred

As far as I can tell, I encountered the same issue, you will need to
setAligment(PositionConstants.Center) on your Label, this works for me,
so this seems to me as a change of layout responsibility.

Oh, sorry, the new GMF version is still 2.1.0 (v20080501) so perhaps the
change is in some underlying plugin like GEF?
Nevertheless, I have to solve the problem....

I noticed the same problem after switching to the latest GMF/GEF/Eclipse.
Some labels are not centered when they were before.
I haven't tried anything yet. I was hoping some changes in .gmfgraph would
help if not I will try to modify the code.

You can set this in the graph configuration as a facet on the label,
just as the example shows.

<labels
name="Callname"
figure="CallFigure"
elementIcon="false"
accessor="//@figures.0/@descriptors.23/@accessors.0">
<facets
xsi:type="gmfgraph:GeneralFacet"
identifier="Alignment"
data="PositionConstants.CENTER"/>
</labels>

Or by code :
fFigureCallnameFigure.setAlignment(PositionConstants.CENTER) ;

greetings, urs.

The change in code does work but the General Facet doesn't for me. There
is no difference in the generated code, the General Facet is ignored.

Quite disturbing, but you are right, and thanks I have to add just
another "@generated not" tag.
So Alex, did you know why the facet don't work ? It should I think.

greetings, urs.
