read source from:
http://www.qt-apps.org/content/show....?content=62383
is a easy example inside ....

I do not understand which is the part in that example code that should lead me to the solution for the problem I posted..
I mean some of you knows the two or three lines of code to send to the default printer,
a file which is in the file system?

Thanks to all

Hi all,

ABout this tematic, I would like to know if there is the possibilitiy to treat binary document the same way as text document..
we, indeed know, that for txt file it is possible to write somethink like:

QFile txtFileOut(txtFile);
txtFileOut.open(QFile::ReadOnly | QFile::Text);
QTextStream txtFileIn(&txtFileOut);
QString txtFileToQString(txtFileIn.readAll());
QTextDocument *document = new QTextDocument(txtFileToQString);
 
QPrinter printer;
 
QPrintDialog *dlg = new QPrintDialog(&printer, this);
   if (dlg->exec() != QDialog::Accepted)
        return;
 document->print(&printer);

QFile txtFileOut(txtFile);
txtFileOut.open(QFile::ReadOnly | QFile::Text);
QTextStream txtFileIn(&txtFileOut);
QString txtFileToQString(txtFileIn.readAll());
QTextDocument *document = new QTextDocument(txtFileToQString);

QPrinter printer;

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

To copy to clipboard, switch view to plain text mode 

is there some possibility to do the same for binary files (doc, pdf, etc..) ?
Thank you very mutch for you kind reply.

Qt doesn't handle such things. If you want things that platform dependent, use platform dependent API. Just be aware there is no magic call that would be able to print any file format. For example for printing postscript or pdf files on KDE you can simply call "kprinter /path/to/file", but you won't be able to print MS Word documents like that, in that case you have to open the document in an appropriate application (like Word itself or Open Office) and call the application's print method manually (or using ActiveX on Windows).

You can use QDesktopServices to open a document in an appropriate application, but this won't get it printed automatically (the application might not even support printing at all).

it means I can't use Qt Api to print a .odt file as well ?
Thx

As for Qt 4.4 that's correct. As far as I know Qt 4.5 will be able to handle the Open Document Format.
