    public class VScrollTable.VScrollTableBody

        colIndex -
        w -

      • getMaxIndent

        protected int getMaxIndent()
        This method exists for the needs of VTreeTable only. May be removed or replaced in the future.

        Returns the maximum indent of the hierarcyColumn, if applicable.
        Returns:
        maximum indent in pixels
        See Also:
        VScrollTable.getHierarchyColumnIndex()

      • calculateMaxIndent

        protected void calculateMaxIndent()
        This method exists for the needs of VTreeTable only. May be removed or replaced in the future.

        Calculates the maximum indent of the hierarcyColumn, if applicable.

        public void moveCol​(int oldIndex,
                    int newIndex)

      • indexOf

        public int indexOf​(com.google.gwt.user.client.ui.Widget row)

      • ensureFocus

        protected void ensureFocus()
        Ensure the component has a focus. TODO the current implementation simply always calls focus for the component. In case the Table at some point implements focus/blur listeners, this method needs to be evolved to conditionally call focus only if not currently focused.
