WebBrowser如何响应window.resizeTo方法？

Question

我使用WTL创建了一个WebBrowser，但是却无法响应js里的window.resizeto方法，是不是我实现的接口有问题？

Answer 1

不知道你怎么实现的。

class ATL_NO_VTABLE CWebBrowser : public CWindowImpl<CWebBrowser>,
         public CComObjectRootEx<CComSingleThreadModel>,
         public CComCoClass<CWebBrowser>,
         public IDispatch,
         public IOleClientSite,
         public IOleInPlaceSite,
         public IOleInPlaceFrame,
         public IDocHostUIHandler

////////////////////////////////////////////////////////

HRESULT CWebBrowser::Init( HWND hParent, CRect& rc )
{
 Create( hParent, rc, _T("Web Host"), WS_VISIBLE | WS_CHILD,
   0, NULL);
 ShowWindow(SW_SHOWNORMAL);

 CRect rcClient;
 GetClientRect( rcClient );

 // Create the WebBrowser control
 CComPtr<IOleObject> spOleObject;
 HRESULT hr = CoCreateInstance(CLSID_WebBrowser, NULL, CLSCTX_INPROC, IID_IWebBrowser2,
           (void**)&m_spWebBrowser);

 if(FAILED(hr) || !m_spWebBrowser)
 {
  return E_FAIL;
 }

 // Query WebBrowser for IOleObject pointer
 m_spWebBrowser->QueryInterface(IID_IOleObject, (void**)&spOleObject);
 if (hr != S_OK)
 {
  //MessageBox(_T("CoCreateInstance failed"));
  return E_FAIL;
 }

 if (spOleObject->SetClientSite(this) != S_OK)
 {
  //MessageBox(_T("SetClientSite failed"));
  return E_FAIL;
 }

 // In-place activate the WebBrower control
 MSG msg;
 GetClientRect(&rcClient);
 hr = spOleObject->DoVerb(OLEIVERB_INPLACEACTIVATE, &msg, this, 0, m_hWnd, &rcClient);
 if (hr != S_OK)
 {
  //MessageBox(_T("DoVerb failed"));
  return E_FAIL;
 }

 m_spWebBrowser = spOleObject;
 if (!m_spWebBrowser)
  return E_FAIL;

 //temp test
 m_spWebBrowser->put_Silent(VARIANT_TRUE);
 //temp test

 // Set up the connection to the WebBrowser control to receive events
 hr = AtlAdvise(m_spWebBrowser, GetUnknown(), DIID_DWebBrowserEvents2, &m_dwCookie);
 if (FAILED(hr))
  ATLTRACE(_T("Failed to Advise\n"));

 // QI for the in-place object to set the size
 m_spInPlaceObject = m_spWebBrowser;
 _ASSERT(m_spInPlaceObject);

 if (m_spInPlaceObject)
  m_spInPlaceObject->SetObjectRects(&rcClient, &rcClient);

  return S_OK;
}

//上面是创建方式
绑定连接点之后可以响应浏览器事件，也可以正常显示，但是对于js里的window.resizeto却无法响应，有文章说需要响应DISPID_WINDOWSETHEIGHT和DISPID_WINDOWSETWIDTH事件，但是调用window.resizeto的时候并没有接收到这两个事件。

Hi jiangsheng
    下面是我的实现方式，请问你有什么建议吗？多谢！

Answer 4

IOleInPlaceSite::OnPosRectChange和IHTMLOMWindowServices的实现在哪里

Answer 5

 STDMETHOD(OnPosRectChange)(LPCRECT lprcPosRect)
 {
  return E_NOTIMPL;
 }
没有实现。调用resizeTo的时候并没有调用这里。

IHTMLOMWindowServices没有实现。

Answer 6

实现IHTMLOMWindowServices和IServiceProvider看看
