how to print an html file?

[patcito]

I have a "QFile myhtmlFile", is there a way to print that easy with
Qt4? I know there is QPrinter but I couldn't find where to set the
file I want to print, anyone?

thanx in advance

Use QPrinter.

QPrinter is a paint device. You need to layout that html file using Qt richtext capabilities (QDocumentLayout probably) and paint that layout "on" the printer (like you were using a QPainter).

To print a content of a HTML file, you would need to use a QTextDocument. I would use something like the following to do it:

HTH

void print()
{
	QFile file("myHTML.html");
        if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
            return;
 
	QString htmlContent;
        QTextStream in(&file);
        in >> htmlContent;
 
	QTextDocument *document = new QTextDocument();
        document->setHtml(htmlContent);
 
        QPrinter printer;
 
        QPrintDialog *dialog = new QPrintDialog(&printer, this);
        if (dialog->exec() != QDialog::Accepted)
            return;
 
        document->print(&printer);
 
	delete document;
}

void print()
{
	QFile file("myHTML.html");
        if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
            return;
		
	QString htmlContent;
        QTextStream in(&file);
        in >> htmlContent;

	QTextDocument *document = new QTextDocument();
        document->setHtml(htmlContent);

        QPrinter printer;

        QPrintDialog *dialog = new QPrintDialog(&printer, this);
        if (dialog->exec() != QDialog::Accepted)
            return;

        document->print(&printer);

	delete document;
}

To copy to clipboard, switch view to plain text mode

and what to do if the file I have to print is a binary file (for instance pdf file, .doc file )??
Thank you for your help

You have to have an application that understands these types of files.
