how to change the style of GWT checkboxcell?

Question

in gwt how do i change the style of checkboxcell? the checkboxcell is inside a gridtable and

datagrid.getColumn(0).setCellStyleNames(SomeCssClass.getMyCss());

does not work

here's a sample of my code

css:

  .checkBoxCss{
            height:25px;
        }

this is for java that extends CSSResource

public interface MyCSS extends CssResource {

    String checkBoxCss();

}

and this is for the Gridtable

class Gridtable{

public DataGrid<MyObject> createDatagrid(){


CheckboxCell myCheckbox= new CheckboxCell(true, false);

Column<MyObject, Boolean> checkCol = new Column<MyObject, Boolean>(myCheckbox) {
            @Override
            public Boolean getValue(MyObject object) {
                return object.isSelected();

            }
        };

}

datagrid.addColumn(checkCol, "Test");
datagrid.getColumn(0).setCellStyleNames(MyResrouces.INSTANCE.MyCSS().checkBoxCss());


}

在应用样式之前，必须使用ensureInjected() ：

MyResrouces.INSTANCE.MyCSS().ensureInjected()
