public abstract class AbstractAttributeEditor<T>
extends CommonEventComposite
implements IAttributeEditor

抽象的属性编辑器基类 继承类实现 setValue getValue 提供 popupWidget 会提供一个 button进行选择 提供 DisplayWidget 会显示widget 没有 会使用缺省的 TextBox

如何自定义个一个属性编辑器 参考 TextBoxAttributeEditor 1.继承此类 2.提供一个属性编辑器的CODE 3.重载 setAttribute getDisplayWidget getPopupWidget
