Hi!
I am trying to create a custom style, with a non-rectangular polygon. (The attached image is a simple example.)
To provide a nice user experience, I would like to ensure that any edge will actually touch the border of the shape itself, rather than the bounding shape.
I know this is possible in GMF itself by overriding the createNodePlate method, but it seems that in Sirius I cannot do this because my edit part is embedded in a CustomStyle edit part. Is this correct? And, if so, is there any obvious way around this?
I had considered an SVG image with transparent background as an alternative, but there the label text spills over into the transparent part of the shape, which is also not ideal. Or is there a clear way to customise this as well?
Many thanks in advance!

Hello,
Indeed, I think that it will be easier to use a workspace image style
with a SVG image having a transparent background. You can then customize
the label edit part and SiriusWrapLabel to compute the size you need to
keep it "inside the drawn shape". You can find how to customize the
style in this documentation:

Steve

Hello,
I cannot recall of any code snippets doing this unfortunatelly. I guess
that in your own EditPart, in createMainFigure() you should add a
SiriusWrapLabel and then compute its bounds to set a size that will keep
it inside the painted shape.
