answering to myself (how cute!)

in class that extends GraphicalEditorWithFlyoutPalette

protected void configureGraphicalViewer() {
super.configureGraphicalViewer();

GraphicalViewer viewer = getGraphicalViewer();
viewer.setEditPartFactory(new ModelEditPartFactory(viewer));

viewer.setKeyHandler(new GraphicalViewerKeyHandler(viewer));
[...]

}

in the edit part factory

private GraphicalViewer viewer;
public ModelEditPartFactory(GraphicalViewer viewer) {
this.viewer = viewer;
}

private EditPart getPartForElement(Object modelElement) {
if (modelElement instanceof YourDiagram) {
DiagramEditPart part = new DiagramEditPart();
viewer.getControl().addControlListener(part);
viewer.addPropertyChangeListener(part);
return part;
}
[...]
}

then DiagramEditPart has to implement ControlListener, so also this method:

public void controlResized(ControlEvent e) {
FigureCanvas source = (FigureCanvas) e.getSource();
//the following returns childrens
List<AbstractModelElement> elements = getCastedModel().getElements();
for(YourElement element : elements) {
if(element.getSize().height < source.getBounds().height) {
Dimension size = element.getSize();
size.height = source.getBounds().height;
element.setSize(size);

}
}

}
