QT 和 MFC

1、mfc窗口上贴qt窗口

HWND wnd = this->GetSafeHwnd();
q_winWidget = new QWinWidget(this->GetSafeHwnd());
m_pWidget = new MyWidget();
QVBoxLayout *vLayout = new QVBoxLayout(q_winWidget);
vLayout->addWidget(m_pWidget);

2、qt窗口上贴mfc窗口

m_pQWidget = new QWinHost(ui_groupLayout);
m_pDlg = new MyDlg;
m_pDlg->Create(MyDlg::IDD, NULL);
m_pDlg->ShowWindow(SW_SHOW);
m_pQWidget->setWindow(m_pDlg->GetSafeHwnd());
