Bordered Nodes looks like a List of SubNodes [message #1773138]

Hallo,

My goal is that I have nodes that look like in this:

index.php/fa/30796/0/

Functionally, I managed to do this by turning the children elements into bordered nodes. But then i have not the look i want. I'd like to have them neatly arranged in a list. This looks like I get it when I make a container element and insert the children as SubNodes there. But then it is no longer possible to combine this with Edges.

My first approach to solving this problem was with an IStyleConfigrationProvider. But if I understood correctly, I can only change the existing style of the element there, but I can't present it in the way I would like to.

My next approach would now be to use a GMF extension points. That seems to me to be very complicated and I wanted to ask if this is the right thing to do before I put energy into it?

Maybe there is a simple build in option that I missed.

Thanks for helping

Thanks for your answer, but this is not a good news.

Hi,

I don't see a solution for your problem.

My new approach is it to make it look like this from the documentation:

https://www.eclipse.org/sirius/doc/specifier/diagrams/images/styles/Graphical_Vocabulary_Bordered_Node.png

I use an Image Node with my Icon and define the Label Position as border. To move the Label on the west border of the node I make my own StyleConfigurationProvider.

But if I Override the method the Label of the first Element is showing on the north boarder and all following are on the east.

    @Override
    public IBorderItemLocator getNameBorderItemLocator(DNode node, IFigure mainFigure) {
      final BorderItemLocator locator = new DBorderItemLocator(mainFigure, PositionConstants.WEST);
      locator.setBorderItemOffset(IBorderItemOffsets.DEFAULT_OFFSET);
      locator.setCurrentSideOfParent(PositionConstants.WEST);
      return locator;
    }

As Workaround I make my own derivation of DBorderItemLocator and override the relocate method so it works.

  @Override
  public void relocate(IFigure borderItem) {
    super.relocate(borderItem);
    

    setPreferredSideOfParent(PositionConstants.WEST);
  }

Maybe I make something wrong or it is a bug?

Thanks again for any help!

HI,
This seems normal to me that you have to customize the locator for label positioning.
The DBorderLocator takes in consideration the Sirius authorized size option and not the original preferred size.

Tried extending default BorderItemLocator to see if it works without overriding the relocate method.

Otherwise if your solution works, not better option.

Regards,

Pierre
