ASCII to PDF

[jaca]

Hello,
In code below I want to convert multiple files in ASCII format PDF. Do not want to use graphical interface. The compilation run ok. But when I run the program a message error is shown.
"Microsoft Visual C + + Runtime Library
This gas application requested the Runtime to terminate it in an unusual way. Plaese contact the application's support team for more information. "
Any idea? Thanks.

When I comment QPlainTextEdit and QPrinter the program does not display the error message.

QPlainTextEdit need QApplication.

add
#include <QApplication>
...
int main(int argc, char **argv)
{
QApplication app(argc, argv);
...

Try using QTextDocument instead of QPlainTextEdit.
