QWebView problem with pdf

Printable View

Hi,

The following code results in an empty pdf file whereas when I show() the component, the html code displays correctly.
Any idea?

Here is the source:

Code:

#include <QtCore>
#include <QtGui>
#include <QtWebKit>
 
 
int main(int argc, char *argv[]) {
	QApplication app(argc, argv, 1);
 
		QPrinter *qPrinter = new QPrinter(QPrinter::HighResolution);
		qPrinter->setOutputFormat(QPrinter::PdfFormat);
qPrinter->setOutputFileName("out.pdf");
 
QFile file("in.txt");
     if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
         return 1;
 
QString text;
     while (!file.atEnd()) {
         text += file.readLine();
     }
 
	QWebView *qWebView = new QWebView();
	qWebView->setMinimumSize(1024,768);
	qWebView->show();
	qWebView->setHtml(text);
	qWebView->show();	
	qWebView->print(qPrinter);
	return app.exec();
}

The file in.txt contains only:

Code:

<html>
<body
helloWorld
</body>
</html>

Thanks for your help.
Best regards,
Oscar

Try setting the viewport size of the associated web page.

Thank you wysota for your reply.

I tried:
qWebView->page()->setViewportSize(QSize(2000,2000));
before
qWebView->print(qPrinter);

But the result is the same...Grrrr

Maybe I've got something wrong in my config.
Do you get a valid pdf with this example? (I'm testing it under Vista)

Best regards,

Re: QWebView problem with pdf

I didn't try. But you don't need a web view widget. All you need is QWebPage with its mainFrame where you can set the content using setHtml().

Re: QWebView problem with pdf

The problem is the same with the use of a QWebPage class...

Here is the code:

Code:

#include <QtCore>
#include <QtGui>
#include <QtWebKit>
 
 
int main(int argc, char *argv[]) {
        QApplication app(argc, argv, 1);
 
                QPrinter *qPrinter = new QPrinter(QPrinter::HighResolution);
                qPrinter->setOutputFormat(QPrinter::PdfFormat);
                qPrinter->setOutputFileName("out.pdf");
 
         QString text = "<html> <body> coucou <br>coucou br>coucou <br>coucou <br>coucou <br>coucou <br>coucou </body> </html>";
 
        QWebPage *qWebPage = new QWebPage();
        qWebPage->mainFrame()->setHtml(text);
        qWebPage->setViewportSize(QSize(2000,2000));
        qWebPage->mainFrame()->print(qPrinter);
        return app.exec();
}

Any idea of what I'm missing?

Best regards,
Oscar

Re: QWebView problem with pdf
Well, I've found a html->pdf converter that's working.

I was missing the following line:
Code:

connect(qWebView, SIGNAL(loadFinished(bool)), this, SLOT(loadFinished(bool)));
Now, everything is ok.

Best regards,
