I'm printing blank pages with QWebView

[ihs280]

Hello everybody,

I'm trying to print a HTML page from QWebView but it always prints nothing but an
empty page

Test::Test(QObject* parent):QObject(parent)
{
	view = new QWebView;
	view->load(QUrl("page.html"));
	view->show();
	connect(view,SIGNAL(loadFinished(bool)),this,SLOT(loadFinished()));
}
 
void Test::loadFinished()
{
	qDebug()<<"load finished";
	QPrinter printer;
	QPrintDialog dialog(&printer);
	dialog.exec();
	view->print(&printer);
}

Test::Test(QObject* parent):QObject(parent)
{
	view = new QWebView;
	view->load(QUrl("page.html"));
	view->show();
	connect(view,SIGNAL(loadFinished(bool)),this,SLOT(loadFinished()));
}

void Test::loadFinished()
{
	qDebug()<<"load finished";
	QPrinter printer;
	QPrintDialog dialog(&printer);
	dialog.exec();
	view->print(&printer);
}

To copy to clipboard, switch view to plain text mode 

Can any one help me with this problem

Try QUrl::fromLocalFile() and make sure QFile::exits() returns true for the files you use.

I am trying to print an image file on printer using QWebview but instead of image blank page is printed. Please find the below code.

void ChartViewer::onprintBtnClicked()
{
    QString fileName = QFileDialog::getOpenFileName(this,"Open File",QString(),"Pdf File(*.png)");
    qDebug()<<"Print file name is "<<fileName;
    if(fileName.endsWith(".png"))
    {
        QPrinter printer;
        QWebView *view = new QWebView;
        QPrintDialog *dlg = new QPrintDialog(&printer,this);
        printer.setOutputFileName(fileName);
        if(dlg->exec() != QDialog::Accepted)
            return;
        view->load(fileName);
        view->print(&printer);
    }
}

void ChartViewer::onprintBtnClicked()
{
    QString fileName = QFileDialog::getOpenFileName(this,"Open File",QString(),"Pdf File(*.png)");
    qDebug()<<"Print file name is "<<fileName;
    if(fileName.endsWith(".png"))
    {
        QPrinter printer;
        QWebView *view = new QWebView;
        QPrintDialog *dlg = new QPrintDialog(&printer,this);
        printer.setOutputFileName(fileName);
        if(dlg->exec() != QDialog::Accepted)
            return;
        view->load(fileName);
        view->print(&printer);
    }
}

If I use view->show() then it has shown the image properly but printed page is coming blank. Request you to please look into the above code and correct me where I am doing wrong.

Request you to please look into the above code and correct me where I am doing wrong.

Including the two blatant memory leaks that happen every time the print button is clicked?

QWebView *view = new QWebView;
QPrintDialog *dlg = new QPrintDialog(&printer,this);

QWebView *view = new QWebView;
QPrintDialog *dlg = new QPrintDialog(&printer,this);
