如何使 CDHTMLDialog 隐藏直到页面加载？

发布于 2024-10-09 13:02:37 字数 67 浏览 0 评论 0原文

调用 DoModal 方法后，将立即显示对话框。但我需要使其不可见，直到页面加载。这可能吗？

谢谢 xx

您好，您可以在开始时将其隐藏

OnInitDialog()
   DWORD dwStyle = GetWindowLong(GetSafeHwnd(), GWL_STYLE);
   dwStyle -= WS_VISIBLE;
   SetWindowLong(GetSafeHwnd(), GWL_STYLE, dwStyle);

，然后在 OnNavigateComplete 中使其可见。
但是，如果您的页面加载速度缓慢，则看起来就像您的应用程序挂起

Hi you can make it hidden at start in

OnInitDialog()
   DWORD dwStyle = GetWindowLong(GetSafeHwnd(), GWL_STYLE);
   dwStyle -= WS_VISIBLE;
   SetWindowLong(GetSafeHwnd(), GWL_STYLE, dwStyle);

and then in OnNavigateComplete make it visible.
But if your page will load slow it will seems like your app hangup

//CYourDialog.cpp

void CYourDialog::OnWindowPosChanging(WINDOWPOS* lpwndpos)
{
     //allow to hide dialog at the startup of dialog,
     //delay the show of dialog until m_bVisible is set
     if(!m_bVisible)
     {
         lpwndpos->flags &= ~SWP_SHOWWINDOW;
     }

     CDialog::OnWindowPosChanging(lpwndpos);
}

//CYourHtmlView.cpp

void CYourHtmlView::OnDocumentComplete()
{
    m_pYourDlg->m_bVisible=TRUE;
    m_pYourDlg->ShowWindow(SW_SHOW);
}
