Fix - QGraphicsTextItem in a tab of QTabWidget cannot get focus

Any QGraphicsTextItems in those tabs which are not the first tab of
QTabWidget, cannot get focus although the tab is current tab of
QTabWidget.But the QGraphicsTextItem in the first tab of QTabWidget can
get focus. i.e. a focus frame (dotted box) appears around the
QGraphicsTextItem. Those QGraphicsTextItems which cannot get focus can
get focus only after the main window is minimized and then maximized.
i.e. After that, a focus frame appears around it.
