QThread/QObject and QTimer

[jpn]

The QTimer object must be created in InfoThread::run() without a parent (preferably on the stack since QThread::exec() blocks) and the connection must be forced as direct

connect(  &timer, SIGNAL( timeout() ), this, SLOT( update() ), Qt::DirectConnection );

connect(  &timer, SIGNAL( timeout() ), this, SLOT( update() ), Qt::DirectConnection );

because QThread itself lives in different thread than what's being executed in QThread::run().
