QGraphicsItem setpos()

[qtuser20]

Hi

I am saving out the properties of a textitem that was created for an image and constructing the item while reloading the image.However i seem to be making some mistake with pos()
Here is what i use:

QDataStream out(&itemfile);
....
.....
out<<textItem->pos();


While reading in ,

QPoint p;
in >> p;
textItem->setPos(p);

this does not work .If i try to test using setPos(100,100), then the item is displayed.
Apparently am making some mistake..

Thanks

What does this return?

qDebug() << p;

qDebug() << p;

Are you sure you're in sync with the stream? Maybe you forgot to write or read something and the contents of the stream is different than you expect?

Hi

While saving out the position, i use

out<<(qint32(textItem->pos().x()));
 out<<(qint32(textItem->pos().y()));
 qDebug() << (qint32(textItem->pos().x()));
 qDebug() << (qint32(textItem->pos().y()));

out<<(qint32(textItem->pos().x()));
 out<<(qint32(textItem->pos().y()));
 qDebug() << (qint32(textItem->pos().x()));
 qDebug() << (qint32(textItem->pos().y()));

To copy to clipboard, switch view to plain text mode 

qDebug() returns the following values:
-----------------------------------------------------
478
46
276
366

While reading in,

qint32 px;
qint32 py;
 
in >> px;
in >> py;
qDebug() <<  px;
qDebug() << py;
.....
textItem->pos().setX(px);
textItem->pos().setY(py);

qint32 px;
qint32 py;

in >> px;
in >> py;
qDebug() <<  px;
qDebug() << py;
.....
textItem->pos().setX(px);
textItem->pos().setY(py);

To copy to clipboard, switch view to plain text mode 

qDebug() returns the following erroneous values:
1075786547
858993459
0
0

I checked the sequence, am writing out and reading in proper order.Is my syntax for setting the coordinates correct ? What am i missing ?

Thank you

I am able to read back other attributes like text,font etc.So the issue is related only to position.

Please provide a minimal compilable example reproducing the problem.

Try to save
While Writing:

QPointF p;
p=TextItem->pos();
out<<p;

QPointF p;
p=TextItem->pos();
out<<p;

To copy to clipboard, switch view to plain text mode 

While Reading:

QPointF p;
in>>p;
TextItem->setPos(p);

QPointF p;
in>>p;
TextItem->setPos(p);

To copy to clipboard, switch view to plain text mode 

I have done like this and I got.
One more thing if there are many No. of Items Whose position is to be saved better go for

QList<QPointF *>

QList<QPointF *>

To copy to clipboard, switch view to plain text mode 

and save the QList.

Thank you .That helped.
