\class Q3SqlEditorFactory
\brief The Q3SqlEditorFactory class is used to create the editors
used by Q3DataTable and Q3SqlForm.
\compat
Q3SqlEditorFactory is used by Q3DataTable and Q3SqlForm to
automatically create appropriate editors for a given QSqlField.
For example if the field is a QVariant::String a QLineEdit would
be the default editor, whereas a QVariant::Int's default editor
would be a QSpinBox.
If you want to create different editors for fields with the same
data type, subclass Q3SqlEditorFactory and reimplement the
createEditor() function.
