详细描述

The Q3SqlEditorFactory class is used to create the editors used by Q3DataTable and Q3SqlForm .

Q3SqlEditorFactory 用于 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 并重实现 createEditor () 函数。
