示例1:

nsresult
PluginStreamListener::SetupPlugin()
{
  NS_ENSURE_TRUE(mDocument, NS_ERROR_FAILURE);
  mPluginDoc->StartLayout();

  nsCOMPtr<nsIContent> embed = mPluginDoc->GetPluginContent();

  // Now we have a frame for our <embed>, start the load
  nsCOMPtr<nsIPresShell> shell = mDocument->GetShell();
  if (!shell) {
    // Can't instantiate w/o a shell
    mPluginDoc->AllowNormalInstantiation();
    return NS_BINDING_ABORTED;
  }

  // Flush out layout before we go to instantiate, because some
  // plug-ins depend on NPP_SetWindow() being called early enough and
  // nsObjectFrame does that at the end of reflow.
  shell->FlushPendingNotifications(Flush_Layout);

  nsIFrame* frame = embed->GetPrimaryFrame();
  if (!frame) {
    mPluginDoc->AllowNormalInstantiation();
    return NS_OK;
  }

  nsIObjectFrame* objFrame = do_QueryFrame(frame);
  if (!objFrame) {
    mPluginDoc->AllowNormalInstantiation();
    return NS_ERROR_UNEXPECTED;
  }

  nsresult rv = objFrame->Instantiate(mPluginDoc->GetType().get(),
                                      mDocument->nsIDocument::GetDocumentURI());
  if (NS_FAILED(rv)) {
    return rv;
  }

  // Now that we're done, allow normal instantiation in the future
  // (say if there's a reframe of this entire presentation).
  mPluginDoc->AllowNormalInstantiation();

  return NS_OK;
}
