Core::EditorManagerPlaceHolder::current() method replacement in Qt Creator 3.0

[serpheroth]

I am developing a Qt Creator plugin. This plugin shows currently opened files as a QTabWidget on top of the editor pane. In Qt Creator 2.8, the code works like the following,
Core::EditorManagerPlaceHolder* holder = Core::EditorManagerPlaceHolder::current();
holder->layout()->addWidget(myTabWidget);

Here is the screen shot for the plugin running in Qt Creator 2.8

However, in Qt Creator 3.0, the method Core::EditorManagerPlaceHolder::current() no longer exists. In this situation how am I able to put the QTabWidget on the top the editor window

Hi and welcome to devnet,

You should bring this topic on the qt-creator mailing list, you'll find there Qt Creator's developers/maintainers (this forum is more user oriented)
