Often, it is desirable to make a number of changes to the model without the
screen constantly repainting. Therefore when you modify the model, nothing
is updated on the screen until you say it's time to do so. You cause the
widget to be refreshed from the data model by issuing a call to
datamodel.setData() with an empty parameter list.
