• Duilib界面需要通过全窗口来拖动窗口位置时，可以在OnNcHitTest函数中通过以下代码实现，也不影响其他控件的使用：

      POINT pt; pt.x = GET_X_LPARAM(lParam); pt.y = GET_Y_LPARAM(lParam);
      ::ScreenToClient(*this, &pt);
  
      RECT rcClient;
      ::GetClientRect(*this, &rcClient);
      RECT rcCaption = m_pm.GetCaptionRect();
      if (pt.x >= rcClient.left && pt.x < rcClient.right && pt.y >= rcClient.top && pt.y < rcClient.bottom) {
          CControlUI* pControl = static_cast<CControlUI*>(m_pm.FindControl(pt));
          if (pControl && _tcscmp(pControl->GetClass(), DUI_CTR_BUTTON) != 0 &&
              _tcscmp(pControl->GetClass(), DUI_CTR_OPTION) != 0 &&
              _tcscmp(pControl->GetClass(), DUI_CTR_TEXT) != 0)
              return HTCAPTION;
      }
  
      return HTCLIENT;
