MFC中静态文本框获取鼠标移动到按钮上的消息

Question

MFC对话框运用程序，对话框上有多个按钮和静态文本框，鼠标移动到不同按钮上时静态文本框输出不同字符串，这个功能怎么实现？我刚学MFC，是个小白，希望各位大神不嫌麻烦，讲详细一点。谢谢！

Answer 1

1.重载PreTranslateMessage函数
2.实现如下代码
BOOL CMouseDlg::PreTranslateMessage(MSG* pMsg)
{
// TODO: Add your specialized code here and/or call the base class
if(pMsg->hwnd == GetDlgItem(IDC_BUTTON1)->GetSafeHwnd() && pMsg->message == WM_MOUSEMOVE)
{
CString windowText;
GetDlgItem(IDC_BUTTON1)->GetWindowText(windowText); //得到按钮文本
GetDlgItem(IDC_STATIC1)->SetWindowText(windowText); //显示到静态文本框
}else if(pMsg->hwnd == GetDlgItem(IDC_BUTTON2)->GetSafeHwnd() && pMsg->message == WM_MOUSEMOVE)
{
CString windowText;
GetDlgItem(IDC_BUTTON2)->GetWindowText(windowText);
GetDlgItem(IDC_STATIC1)->SetWindowText(windowText);
}
return CDialog::PreTranslateMessage(pMsg);
}
