QGraphicsItem And QGraphicsScene

Ketan__Patel__0011

Hello Friends And Qt Experts

I am facing the problem B/W QGraphicsItem And QGraphicsScene

follow my code
.h File

class Custome_Scene : public QGraphicsScene
{
    Q_OBJECT
public:
    Custome_Scene(QObject* parent = 0);
    void mouseMoveEvent(QGraphicsSceneMouseEvent* mouseEvent) override;
    void mousePressEvent(QGraphicsSceneMouseEvent* mouseEvent) override;
    void mouseDoubleClickEvent(QGraphicsSceneMouseEvent* mouseEvent) override;
}

.cpp File

Custome_Scene::Custome_Scene(QObject *parent)
{

}
void Custome_Scene::mouseMoveEvent(QGraphicsSceneMouseEvent *mouseEvent)
{
    qDebug() << mouseEvent->scenePos();
}
void Custome_Scene::mousePressEvent(QGraphicsSceneMouseEvent *mouseEvent)
{

}
void Custome_Scene::mouseDoubleClickEvent(QGraphicsSceneMouseEvent *mouseEvent)
{

}

As you see my code
when i try to get my current position of my mouse from QGraphicsScene
it will work fine

but when i Add Any QGraphicsItem in my Custome_Scene that time QGraphicsItem can be Movable or Selectable

follow my code for Item Add

Custome_Scene *customescene = new Custome_Scene ();
QGraphicsRectItem *Item_Rect = new QGraphicsRectItem();
Item_Rect->setFlags(QGraphicsItem::ItemIsMovable | QGraphicsItem::ItemIsSelectable);
Item_Rect->setRect(10,10,100,100);
Item_Rect->setZValue(1);
Item_Rect->setVisible(true);
customescene->addItem(Item_Rect);

I have tried to understand what you are saying/your problem is but I do not. In principle your code looks fine. So what is the question, can you rephrase it?

Thanks You For Reply

As You see my code
i was add RectangleItem in my Custome_Scene

@Ketan__Patel__0011 said in QGraphicsItem And QGraphicsScene:

Item_Rect->setFlags(QGraphicsItem::ItemIsMovable | QGraphicsItem::ItemIsSelectable);

Accoranding to this my Item_Rect should be movable or selectable in my Custome_Scene but i can handle it.

i can't select or move over the my Custome_Scene .

mousePressEvent

Basic c++ - if you override a function and also want the functionality of the base class you should also call the base class implementation of this function.
