    @guru007 If you use widgets there is nothing to check as those do not use GPU.

      @guru007 Again: you're currently using widgets! Widgets do not use GPU - what do you want to check?
      If you're planning to switch to QML, then take one of QML/QtQuick examples.

        @jsulm Now I am also talking about Qml. I think colliding mice is right example to test.
        Am I right dear?

            problem is solved by using QgrpahicsView with Qimage.
            I draw text on QImage And Display it in QGraphicScene.
            Cpu usage decreased to 45 % .
            Thanks for ur replies.
