I have tried the following but it still does not work. However, the return
value of LoadURI is 0;
nsCOMPtr<nsIWebNavigation>
spIWebNavigation1(do_QueryInterface(mRootDocShell));
if (spIWebNavigation1)
{
nsCOMPtr<nsIURI> newUri;
res = NS_NewURI(getter_AddRefs(newUri), sUrl);
res = spIWebNavigation1->LoadURI(sUrl.get(),
nsIWebNavigation::LOAD_FLAGS_NONE);
// res = spIWebNavigation1->GoBack();
}
I got the mRoorDocShell from the following
nsCOMPtr<nsIWindowMediator> windowMediator =
do_GetService(kWindowMediatorCID, &rv);
if ( NS_SUCCEEDED( rv ) )
{
PRBool hasParentWindow = PR_FALSE;
nsCOMPtr<nsISimpleEnumerator> windowEnumerator;
nsCOMPtr<nsIDOMWindow> content;
nsCOMPtr<nsIXULWindow> xulWindow;
if ( NS_SUCCEEDED(windowMediator->GetXULWindowEnumerator(nsnull,
getter_AddRefs(windowEnumerator))) )
{
// Get Each Dom window
PRBool more;
windowEnumerator->HasMoreElements(&more);
while(more)
{
nsCOMPtr<nsISupports> nextWindow = nsnull;
rv = windowEnumerator->GetNext(getter_AddRefs(nextWindow));
if ( NS_SUCCEEDED( rv ) && nextWindow )
{
xulWindow = do_QueryInterface(nextWindow);
if (xulWindow)
{
mXulWindow = xulWindow;
nsCOMPtr<nsIDocShellTreeItem> shellAsTreeItem;
nsCOMPtr<nsIDOMDocument> document;
nsCOMPtr<nsIDOMWindow> domWin;
nsCOMPtr<nsIWebBrowser> webBrowser;
xulWindow->GetPrimaryContentShell(getter_AddRefs(mShellAsTreeItem));
if (mShellAsTreeItem != nsnull)
{
nsCOMPtr<nsIDocShellTreeOwner> treeOwner;
nsCOMPtr<nsIWidget> widget;
nsCOMPtr<nsIDocShell> rootDocShell
(do_QueryInterface(mShellAsTreeItem));
mRootDocShell = rootDocShell;
domWin = do_GetInterface(mShellAsTreeItem);
m_DomWin = domWin;
if (m_fIsDialog)
{
nsIScriptGlobalObject *pScript;
nsIDocShell *pDocShell;
m_TopDomWin->QueryInterface
(NS_GET_IID(nsIScriptGlobalObject), (void**) &pScript);
pScript->GetDocShell (&pDocShell);
mRootDocShell = pDocShell;
}
rv = DOMWindowToWidget(domWin,
getter_AddRefs(widget));
if ( NS_SUCCEEDED( rv ) && widget )
{
m_hWndCurrentDoc =
(HWND)widget->GetNativeData(NS_NATIVE_WINDOW);
}
rv =
domWin->GetDocument(getter_AddRefs(mDocument));
}
hasParentWindow = PR_TRUE;
break;
} // xulWindow
}//next window
windowEnumerator->HasMoreElements(&more);
} // while
}
