In symbian(tested in N97), the actions of QMenu are not returned by the added order from function "QList<QAction *> QWidget::actions () const". There is not the problem in simulator.

My codes:
1)
typedef enum

{ PaintAct, LineAct, SquareAct, RectangleAct, CircleAct, EllipseAct, TriangleAc, PolygonAct }

GraphicsMenuActions;

2)
addAction(QIcon(":/icon/scribble.png"), QString("draw"));
addAction(QIcon(":/icon/line_shape.png"), QString("line"));
addAction(QIcon(":/icon/square_shape.png"), QString("square"));
addAction(QIcon(":/icon/rectangle_shape.png"), QString("rectangle"));
addAction(QIcon(":/icon/circle_shape.png"), QString("circle"));
addAction(QIcon(":/icon/ellipse_shape.png"), QString("ellipse"));
addAction(QIcon(":/icon/triangle.png"), QString("triangle"));
addAction(QIcon(":/icon/polygon.png"), QString("polygon"));

3)
signalMapper = new QSignalMapper(this);

int i=PaintAct;
foreach(QAction *action, this->actions())

{ connect(action, SIGNAL(triggered()), signalMapper, SLOT(map())); signalMapper->setMapping(action, i); i++; }

connect(signalMapper, SIGNAL(mapped(int)), graphicsScenePaint, SLOT(onGraphicsMenuActionTriggered(int)));

4) By clicking actions in menu, the painting program will draw wrong graphics in Symbian. The same action in simulator is right.
