继承setactiveview问题 [英] Inherit setactiveview issue

问题描述

你好，



我在VS NET 2003上用C ++编写了一个旧的MFC项目，我有以下问题。



我的项目是一个SDI，我把SplitterWnd放到两个视图中。

我想检测视图激活更改以执行一些激活/停用。



因为它似乎与我正在寻找的完全一致，我试图在我的CMainFrame中继承CFrameWnd :: SetActiveView（CView * pViewNew，BOOL bNotify）（公共派生自CFrameWnd）在公共场合如下：



in .h：

public：

void SetActiveView（CView * pViewNew， BOOL bNotify = TRUE）;


$ c $ b in .cpp：

void CMainFrame :: SetActiveView（CView * pViewNew，BOOL bNotify）

{

Beep（440,200）;

CFrameWnd :: SetActiveView（pViewNew，bNotify）;

}



我的函数从未调用过; CFrameWnd :: SetActiveView（）仍然是被调用的那个。



也许，有一个消息处理程序或其他东西要添加？或者特定的限制/不兼容/错误？



它应该很简单，但是......



提前感谢您的帮助，

Eric



我的尝试：



继承CFrameWnd :: SetActiveView（）

Hello,

I have an old MFC project in C++ on VS NET 2003 and I have the following issue.

My project is a SDI in which I put a SplitterWnd to have two views.
And I would like to detect view activation change to perform some activations/desactivations.

As it seems to correspond exactly to what I am looking for, I tried to inherit CFrameWnd::SetActiveView(CView* pViewNew, BOOL bNotify) in my CMainFrame (public derived from CFrameWnd) in public as follow:

in .h:
public:
void SetActiveView(CView* pViewNew, BOOL bNotify = TRUE);

in .cpp:
void CMainFrame::SetActiveView(CView* pViewNew, BOOL bNotify)
{
Beep (440, 200);
CFrameWnd::SetActiveView(pViewNew, bNotify);
}

And my function is never called; the CFrameWnd::SetActiveView() remains the one which is called.

Perhaps, there is a message handler or something else to add? or a specific limitation/incompatibility/bug?

It should be easy, but...

Thank you in advance for your help,
Eric

What I have tried:

Inherit CFrameWnd::SetActiveView()

推荐答案

查看文档： CFrameWnd类 [ ^ ]，这不是虚函数，这意味着它不可覆盖。

Looking at the documentation: CFrameWnd Class[^], this is not a virtual function, which means it is not overridable.
