[Qt-creator] Core::EditorManagerPlaceHolder::current() method replacement in Qt Creator 3.0

[Xiaofeng Wu]

I try the method you told me. The code is like the following
bool EditorTabsPlugin::eventFilter(QObject *obj, QEvent *event)
{
  if (event->type() == QEvent::ParentChange) {
    Core::EditorManager* manager = Core::EditorManager::instance();
    Core::EditorManagerPlaceHolder* placeHolder =
      static_cast<Core::EditorManagerPlaceHolder*>(manager->parent());
    placeHolder->layout()->addWidget(bar);
  }
  return false;
}

The result is that it creates another window and put the widget in it
instead of placing the widget on top of the editor panel.

Where is the problem?
