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;
