详细描述

The Q3EditorFactory class is used to create editor widgets for QVariant 数据类型。

Each editor factory provides the createEditor () function which given a QVariant will create and return a QWidget that can edit that QVariant . For example if you have a QVariant::String 类型， QLineEdit would be the default editor returned, 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 Q3EditorFactory 并重实现 createEditor () 函数。
