Usage

When you change any visual property of a PowerBuilder object
by calling Set<type>field functions,
the property is changed but the property is not refreshed in the
graphical user interface. UpdateField refreshes
the visual properties of PowerBuilder objects. You must call this
function explicitly when changing any visual property with the Set<type>field functions.
