示例1: GetView
NS_IMETHODIMP nsTreeBoxObject::GetView(nsITreeView * *aView)
{
if (!mTreeBody) {
if (!GetTreeBody()) {
// Don't return an uninitialised view
*aView = nsnull;
return NS_OK;
}
if (mView)
// Our new frame needs to initialise itself
return mTreeBody->GetView(aView);
}
if (!mView) {
nsCOMPtr<nsIDOMXULElement> xulele = do_QueryInterface(mContent);
if (xulele) {
// See if there is a XUL tree builder associated with the element
nsCOMPtr<nsIXULTemplateBuilder> builder;
xulele->GetBuilder(getter_AddRefs(builder));
mView = do_QueryInterface(builder);
if (!mView) {
// No tree builder, create a tree content view.
nsresult rv = NS_NewTreeContentView(getter_AddRefs(mView));
NS_ENSURE_SUCCESS(rv, rv);
}
// Initialise the frame and view
mTreeBody->SetView(mView);
}
}
