MFC 控件 “模板”+“派生”类的创建方法

Question

我

我想要创建一个ListBox的派生类，并且采用模板，代码大致意思如下

in H File

template <class Type,...Args>
class CExListBox : public CListBox
{
DECLARE_DYNAMIC(CExListBox)
public:
CExListBox();
virtual ~CExListBox();

protected:
DECLARE_MESSAGE_MAP()

...... some function in class

｝

in CPP File

IMPLEMENT_DYNAMIC(CExListBox, CListBox)

template <class Type, class...Args>

CExListBox<Type,...Args>::CExListBox()

{

}

template <class Type, class...Args>

CExListBox<Type,...Args>::~CExListBox()

{

}

BEGIN_MESSAGE_MAP(CExListBox<Typem,...Args>, CListBox)

END_MESSAGE_MAP()

........some function in class

有人能否帮我看一下

DECLARE_DYNAMIC(CExListBox)

IMPLEMENT_DYNAMIC(CExListBox, CListBox)

BEGIN_MESSAGE_MAP(CExListBox<Typem,...Args>, CListBox)

and

END_MESSAGE_MAP()

这几个宏到底应该怎么写，我怎么写都会编译报错，还有其他的地方我有没有写错的

双手抱拳感谢。。。

Answer 1

更正一下，第一行代码写错了，应该是

template <class Type,class...Args>
class CExListBox : public CListBox
{
DECLARE_DYNAMIC(CExListBox)

.......................

Answer 2

参考这个文章： http://www.codeproject.com/Articles/351/Templates-and-MFC

可能类似这样的形式：

BEGIN_TEMPLATE_MESSAGE_MAP(<class T>, TListBox<T>, CJBListBox)
    ON_WM_DESTROY()
END_MESSAGE_MAP()

还有这个MSDN 的sample
