beginUpdate()
Prevents the widget from refreshing until the endUpdate() method is called.
The beginUpdate() and endUpdate() methods prevent the widget from excessive updates when you are changing multiple widget settings at once. After the beginUpdate() method is called, the widget does not update its UI until the endUpdate() method is called.
