按钮之中包含按钮

按钮之中包含按钮

本程序介绍如何实现在按钮中包含按钮，参见下图。

使用方法如下。在CDialog派生类中添加一个CHiButton成员变量m_wndHiButton，在OnInitDialog中调用 m_wndHiButton.SubclassDlgItem(IDC_BUTTON1, this)即可。这样，只要用户点击按钮，程序就会按下面逻辑进行判断：

void CTestDlg::OnHibutton()

{

if (m_hiButton.m_bInsideButton)

AfxMessageBox(_T("TestInside"));

else

AfxMessageBox(_T("Test"));

}

用户可以附加位图、图标、文本或者光标到该控件上。
