Hei,
Even we got the code, the following code will make the label come in the
center. I will try to make a layout of it
setLayoutManager(new StackLayout() {
public void layout(IFigure figure) {
Rectangle r = figure.getClientArea();
List children = figure.getChildren();
IFigure child;
Dimension d;
for (int i = 0; i < children.size(); i++) {
child = (IFigure)children.get(i);
d = child.getPreferredSize(r.width, r.height);
d.width = Math.min(d.width, r.width);
d.height = Math.min(d.height, r.height);
Rectangle childRect = new Rectangle(
r.x + (r.width - d.width)/2,
r.y + (r.height - d.height)/2,
d.width,
d.height);
child.setBounds(childRect);
}
}
});
Thanks,

Hi there,
I tried this to get the label of my elliptical node centred. But it
doesn't work. I put it in the CreateNodeFigure-method of *EditPart of
the Figure.
Is it the problem because of the rectangle as box for the ellipse? I
also iterated a step deeper with the children, so I can get the label of
the ellipse, but here too -> nothing happens with the label, I is top
centred but not vertically.
Thanks for help
