InlineDateField gap between Caption

Hey,

i would like to get an gap between the DateField and the caption. I tried it with setMargin on the outer layout but it don´t works.
I create the InlineDateField like this:

layout = new VerticalLayout();

		InlineDateField calendar = new InlineDateField(this.caption);
		calendar.setResolution(InlineDateField.RESOLUTION_DAY);
		layout.addComponent(calendar);

I hope someone can help me!
Thanks
Dominik

I solve the problem.

I set the caption from the InlineDateField to null and added a own Label.
