如何在Groovy中设置进度条的值？

Question

I am using a vaadin progressbar in groovy. I have a variables Total = 10, Right =5, left =3, I need to show Left=Total-(right+left), and visualize it in the progressbar.All are integer value. In my code in am using a propertydatasource. How can i use these values and load into the progressabr. Please help. I am using vaadin 7.6.3.

Progressbar defining:

    private final ProgressBar _progress;
    public View() {

    _progress = new ProgressBar();
    _progress.setWidth("100%");
    _Layout.addComponents(_progress);  // here Layout is horizontal layout 
                                 fewcodes are missing which are not related.
    }
    public ProgressBar get_progress() {
            return _progress;
    }

In an another java class i am trying to set the progressbar data using the 'setPropertyDataSource' here '_view' is my Ui where i am trying to load.

_view.get_progress().setPropertyDataSource(_equipmentItem.getItemProperty(Equipment.Total));

The output i wanted to achieve is.

Did you follow the examples from the docs? See here . Basically you can call setValue within range 0.0f to 1.0f (see javadoc ) where 0.0f is no progress and 1.0f is full progress. That means you can use current / (float)max formular to calculate your progress value.
