SpinnerItem and SliderItem larger

[lazinskip]

Hi, I am developing application for big 19" touch screen. I need all components bigger then usually. My question: Is there possibility to make spinner bigger. The obvious way through setHeight() does not work (picker icon does not grow bigger together with editor part, also setPickerIconWidth() does not work)

public class SpinnerTest implements EntryPoint {
	public void onModuleLoad() {
		VLayout vl = new VLayout();
		DynamicForm frmSpinner = new DynamicForm();
		SpinnerItem spiHours = new SpinnerItem("spiHours");
		spiHours.setTitle("<span style='font-size:22'>spiHours</span>");
		spiHours.setMin(0);
		spiHours.setMax(16);
		spiHours.setStep(0.5);
		spiHours.setHeight(40);
		spiHours.setPickerIconWidth(50);
		SelectItem siSelect = new SelectItem("siSelect", "<b>select Item</b>");
		siSelect.setHeight(40);
		siSelect.setPickerIconWidth(50);
		frmSpinner.setFields(spiHours, siSelect);
		vl.addMember(frmSpinner);
		RootPanel.get().add(vl);
	}
}

as you can see from screen.png SelectItem picker icon is reacting when height of te component is growing, additionally I can use setPickerIconWidth method on SelectItem. For SpinnerItem there is no effect.

And another question: How to make SliderItem bigger ?
I am using smartgwt 2.2, gwt 2.0.3 in development mode
