Vaadin HorizontalSplitPanel: Set right side width in pixels

I can set the left side width of a HorizontalSplitPanel in pixels like below.

splitter.setSplitPosition(40, Sizeable.Unit.PIXELS);

With above, since the split position is 40 pixels, the left side of splitter is 40 pixels in width. There is a certain case where I want to specify the width of right side of the splitter in pixels.

But, I cannot set the right side with in above way because there's no way to find the total width of the splitter. If I could get the total width, I could have done it like below.

splitter.setSplitPosition(splitter.totalWidth() - 40, Sizeable.Unit.PIXELS);

So, is there any way I can define the right side width in pixels?

You can "reverse" the split position. See setSplitPosition(float pos, Sizeable.Unit unit, boolean reverse):

reverse - if set to true the split splitter position is measured by the second region else it is measured by the first region

E.g.:

// run with `spring run vaadin.groovy`
@Grapes([
@Grab('org.vaadin.spring:spring-boot-vaadin:0.0.5.RELEASE'),
@Grab('com.vaadin:vaadin-server:7.5.9'),
@Grab('com.vaadin:vaadin-client-compiled:7.5.9'),
@Grab('com.vaadin:vaadin-themes:7.5.9'),
])
import org.vaadin.spring.annotation.VaadinUI
import com.vaadin.server.VaadinRequest
import com.vaadin.ui.*
import com.vaadin.annotations.*
import com.vaadin.server.Sizeable

@VaadinUI
@Theme("valo")
class MyUI extends UI {
        protected void init(VaadinRequest request) {
                setContent(new HorizontalSplitPanel(new Label("A"), new Label("B")).with{
                        setSplitPosition(40, Sizeable.Unit.PIXELS, true /*!*/)
                        it
                })
        }
}
