示例1: SetShownScene

void SceneStructureWindow::SetShownScene(const ScenePtr &newScene)
{
    if (!scene.expired() && newScene == scene.lock())
        return;

    ScenePtr previous = ShownScene();
    if (previous)
    {
        disconnect(previous.get());
        Clear();
    }

    scene = newScene;
    treeWidget->SetScene(newScene);

    if (newScene)
    {
        // Now that treeWidget has scene, it also has UndoManager.
        UndoManager *undoMgr = treeWidget->GetUndoManager();
        undoButton_->setMenu(undoMgr->UndoMenu());
        redoButton_->setMenu(undoMgr->RedoMenu());
        connect(undoMgr, SIGNAL(CanUndoChanged(bool)), this, SLOT(SetUndoEnabled(bool)), Qt::UniqueConnection);
        connect(undoMgr, SIGNAL(CanRedoChanged(bool)), this, SLOT(SetRedoEnabled(bool)), Qt::UniqueConnection);
        connect(undoButton_, SIGNAL(clicked()), undoMgr, SLOT(Undo()), Qt::UniqueConnection);
        connect(redoButton_, SIGNAL(clicked()), undoMgr, SLOT(Redo()), Qt::UniqueConnection);

        Scene* s = ShownScene().get();
        connect(s, SIGNAL(EntityAcked(Entity *, entity_id_t)), SLOT(AckEntity(Entity *, entity_id_t)));
        connect(s, SIGNAL(EntityCreated(Entity *, AttributeChange::Type)), SLOT(AddEntity(Entity *)));
        connect(s, SIGNAL(EntityTemporaryStateToggled(Entity *, AttributeChange::Type)), SLOT(UpdateEntityTemporaryState(Entity *)));
