[Qt-creator] Two questions

[Igor Mironchik]

Hi, I have two questions.

First, I think should be easy, how to say to QtCreator not to do insert 
spaces instead of tabs? And how to say him to make indentation with tabs 
instead of spaces?

And second, why autocompletion doesn't work for "d" member in the next 
example:

In header:

class Test {
public:
     Test();

     void doIt();

private:
     Q_DISABLE_COPY( Test )

     class TestPrivate;
     QScopedPointer< TestPrivate > d;
};

In source:

class Test::TestPrivate {
public
     QString m_string;
};

Test::Test()
     :    d( new TestPrivate )
{
}

void
Test::doIt()
{
     qDebug() << d-> // And here autocompletion doesn't work. Why?
}
