But, when you link them in the application, the error msg will be displayed as above. It is just for the reason that: the compiler cann't locat the correct mygrid for class   A or B with the same name "mygrid->;show()". So, just to rename aGrid for the class A's mygrid and bGrid for class B. 在make時出現的聯接錯誤:到底這個多重定義是在哪個文件中? of course, you can define them as private. [ 關閉窗口 ]
