How can I set the background color for each child GoListGroup within a GoBoxNode so that the whole GoListGroup area has the same background color? Right now, setting the GoListGroup’s BrushColor only effect the background color underneath the text, as in the second attribute below.
GoListGroup doesn’t support a color per item, just a background color. Look at class ClassDiagramNodeItem in ClassDiagramNode to see how it fills the width with a GoText.
