Getting Chart as picture

Hello friends,

my problem is with google chart api. When I create an chart with

Code:

---

http://chart.apis.google.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World

---

I do right click on the picture to get the pie as image.

with php I can get it dynamically like this

Code:

---

<?php
file_put_contents('graph.png');
file_get_contents('http://chart.apis.google.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World");
?>

---

Is there a way to get the image with QT classes ????

Http Request with all the data->Reply data result in QByteArray->convert data to pixmap->display

Simulate the process with Http debugger to see what is going on with the requests and replies and simulate it with Qt.

Hi

Try this

Code:

---

Widget::Widget(QWidget *parent) : QWidget(parent), ui(new Ui::Widget)
{
    ui->setupUi(this);
    http   = new QHttp;
    chart  = new QByteArray;
    QHttpRequestHeader header("POST", "/chart?cht=p3&chf=bg,s,65432100&chd=t:60,40&chs=250x100&chl=Hello|World");
    header.setValue("Host","chart.apis.google.com");
    http->setHost("chart.apis.google.com");
    http->request(header, *chart); 
    QApplication::processEvents();
    connect(http, SIGNAL(done(bool)), this, SLOT(showChart()));
}
 
void Widget::showChart()
{
    *chart = http->readAll();
    QPixmap chartPixmap;
    chartPixmap.loadFromData(*chart);
    ui->label->setPixmap(chartPixmap);
}
