\brief The TQSqlEditorFactory class is used to create the editors
used by TQDataTable and TQSqlForm.
\ingroup database
\module sql
TQSqlEditorFactory is used by TQDataTable and TQSqlForm to
automatically create appropriate editors for a given TQSqlField.
For example if the field is a TQVariant::String a TQLineEdit would
be the default editor, whereas a TQVariant::Int's default editor
would be a TQSpinBox.
If you want to create different editors for fields with the same
data type, subclass TQSqlEditorFactory and reimplement the
createEditor() function.
