QGraphicsScene is an QObject that can have signal/slot connection...

thanks, but I dont know, which signal I could use...

Code:

---

textureView = new TextureView();
.
.
.
TextureView::TextureView(QWidget *parent)
    : QGraphicsView(parent)
{
    textureScene = new QGraphicsScene(this);
    textureScene->setSceneRect(0, 0, 180, 200);
    setScene(textureScene);
    addItems();
}
 
void TextureView::addItems()
{
    ImageItem *image;
    image = new ImageItem(1, QPixmap(":/images/background1"/* + i*/));
    image->setPos(0, 0);
    textureScene->addItem(image);
}
void TextureView::mouseReleaseEvent(QMouseEvent *event)
{
    if (QGraphicsItem *item = itemAt(event->pos())) {
        if (ImageItem *image = qgraphicsitem_cast<ImageItem *>(item))
            setId(image->id());
    }
    QGraphicsView::mouseReleaseEvent(event);
}
void TextureView::setId(int id)
{
    itemId=id;
}
 
ImageItem::ImageItem(int id, const QPixmap &pixmap, QGraphicsItem *parent,
                     QGraphicsScene *scene)
    : QGraphicsPixmapItem(pixmap, parent, scene)
{
    recordId = id;
}

I would like to make reaction on mouseReleaseEvent but this proteeted function isnot singal. Could you help me please again? Thank you very much

I am trying to write own singnal and slot for connection between 2 scene

Code:

---

connect(textureView, SIGNAL(textureId(int)), scene, SLOT(getTextureId(int)));

---

how should write this signal? How I get information, which integer will be send to slot?
I cannot imagine how to set integer, in order to send to slot

when I tried it now, I have...

Code:

---

void TextureView::textureId(int id)
{
 
}

---

yes it is free because I dont know, how to set integer, which will be send

So I tried to compiled and in moc_*.cpp file It create me

Code:

---

void TextureView::textureId(int _t1)
{
    void *_a[] = { 0, const_cast<void*>(reinterpret_cast<const void*>(&_t1)) };
    QMetaObject::activate(this, &staticMetaObject, 0, _a);
}

---

but compiler wrote error that in moc_*.coo is first definition of this signal.
Please help me, I didnot wrote any own signals thanks

edit:
I would like to send itemId to scene to slot SLOT(getTextureId(int))

Code:

---

void TextureView::setId(int id)
{
    itemId=id;
}

my problem fixed :) you can lock this thread :)
It was my stupid mistake... :mad: :o
