Modify QDockWidget title background when in focus

[ronno]

I have two QDockWidgets:

// Create the two dockable widgets.
QDockWidget *a_dock = new QDockWidget(tr("abc"));
QDockWidget *b_dock = new QDockWidget(tr("xyz"));

// Add widgets to above dockables...

// Add the two dockable widgets created above.
addDockWidget( Qt::LeftDockWidgetArea, a_dock );
addDockWidget( Qt::BottomDockWidgetArea, b_dock );

Is there a way to have the corresponding QDockWidgets' title bar to become highlighted when the embedded widgets are in focus?
