MFC中静态文本框获取鼠标移动到按钮上的消息

Posted 2023-03-09

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！

参考技术A 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);
