当鼠标光标在MFC应用程序中的按钮上时，无法设置手形光标

Question

I created a new custom button class (derived from CButton). Overrode the OnMouseMove API in the new custom class. When my mouse cursor moves over the button in a dialog, the OnMouseMove API in the custom button class is called successfully but the cursor symbol is not changed to Hand symbol :(

In the OnMouseMove() API I have the following code:

if (m_hClickCursor == NULL) 
    m_hClickCursor = AfxGetApp()->LoadCursor(IDC_CLICK_CURSOR);
if (m_hClickCursor) 
    this->SetCursor(m_hClickCursor);

Here,
IDC_CLICK_CURSOR is a reference to hand cursor (I use the same hand cursor at other places in my app).
m_hClickCursor is the handle to the cursor

Please Help !!

Thanks, -Nayan

您必须处理WM_SETCURSOR才能执行此操作。
