Convert QPixmap to QByteArray ?

[probine]

I am using a QPixmap to take a screenshot of my desktop. I would like to convert this QPixMap to QByteArray.

How ?

Have you tried it using QPixmap::save. From the Qt Docs:

QPixmap pixmap;
            QByteArray bytes;
            QBuffer buffer(&bytes);
            buffer.open(QIODevice::WriteOnly);
            pixmap.save(&buffer, "PNG");

QPixmap pixmap;
            QByteArray bytes;
            QBuffer buffer(&bytes);
            buffer.open(QIODevice::WriteOnly);
            pixmap.save(&buffer, "PNG");

To copy to clipboard, switch view to plain text mode

Thanks for the answer.

Now I have everything in a QByteArray. Now, I am parsing my QByteArray which has XML format. The parsing is done with DOM.

I need an element of the XML (QByteArray) to be comverted or used as QByteArray.

How ?

I do not want to transform the element to string, because I think I will loose the picture.

void Message :: parseScreenshot(QByteArray incomingMessage)
{
     QDomDocument doc("messageIn");
     doc.setContent(incomingMessage);
     QDomElement docElem = doc.documentElement();
     QDomNode n = docElem.firstChild();
     n = n.nextSibling();
     QDomElement e = n.toElement();
     QByteArray screenshot = e // to QByteArray. what should be here ?
     chatGui->screenshot(screenshot);
}

void Message :: parseScreenshot(QByteArray incomingMessage)
{
     QDomDocument doc("messageIn");
     doc.setContent(incomingMessage);
     QDomElement docElem = doc.documentElement();
     QDomNode n = docElem.firstChild();
     n = n.nextSibling();
     QDomElement e = n.toElement();
     QByteArray screenshot = e // to QByteArray. what should be here ?
     chatGui->screenshot(screenshot);
}

I guess you must do something like that

QByteArray screenshot;
screenshot.setRawData(e.text().data(),e.text().lenght());

QByteArray screenshot;
screenshot.setRawData(e.text().data(),e.text().lenght());
