Qpainter, drawPolygon, fillpath, bouding rect ....

        break;
    }
    update();
}
 
int frameX::getFrameStatus() const
{
    return this->StatusState;
}

if the inside of the polyon is clicked it turns blue otherwise transparent.

But everytime if i just move over with the cursor, the painter paints the bounding rect
white -> the green outline which is painted in a other class is overpainted.
