I've done this : do you think I can rely on CSS style name ?
public abstract class TabLayoutPanelWithAddTabButton extends
TabLayoutPanel implements ClickHandler {
public TabLayoutPanelWithAddTabButton(double barHeight, Style.Unit
barUnit) {
super(barHeight, barUnit);
Image img = new Image(....);
// we ar looking for tabBar to move it to the right
double space = (barHeight-img.getHeight())/2.0;
LayoutPanel panel = (LayoutPanel)getWidget();
int widgetCount = panel.getWidgetCount();
for (int i=0; i<panel.getWidgetCount();i++) {
Widget w = panel.getWidget(i);
if(w.getStyleName().equals("gwt-TabLayoutPanelTabs")) {
panel.setWidgetLeftRight(w, img.getWidth()+2*space-6,
Style.Unit.PX, 0, Style.Unit.PX);
}
}
panel.insert(img, 0);
panel.setWidgetLeftWidth(img, space, Style.Unit.PX,
img.getWidth(), Style.Unit.PX);
panel.setWidgetTopHeight(img, space, Style.Unit.PX,
img.getHeight(), Style.Unit.PX);
img.getElement().setTitle("Add a new tab");
img.addClickHandler(this);
}
@Override
public void onClick(ClickEvent event) {
addNewTab();
}
/**
* Implements this ta add a new Tab
*/
public abstract void addNewTab();
}

Christophe
