Look for qPrintable(...) ;-)

Is QString::toLatin1() what you are looking for??

QString text="text";
int ret = QMessageBox::warning(this, tr("My Application"), text.toLatin1(), QMessageBox::Ok);

QString::toLatin1() returns QByteArray neither QString nor const char *.
Also QMessageBox takes QString as parameter which doesn't cause problem. But qWarning, qDebug takes const char * as parameter and you can use qPrintable to convert QString to const char *

Hi,

If you want to use cout to print, I have attached two files to this email...qstd.cpp and qstd.h. To use the standard cout syntax include these files in your project and add the namespace using command - using namespace qstd - to any scope in which you want to use cout (and include the "qstd.h" header file of course).

I did not write these files myself, but stumbled upon them somewhere on the web while trying to solve a problem similiar to yours when I first started with Qt. I give full credit, thanks and kudo's to the unamed author....cout has worked flawlessly for me.

Hope this helps....

If you just want to print one or two you can always use the toStdString() method. So:


QString str = "hello";
std::cout<<str.toStdString()<<std::endl;


would print

hello

i still like using the good old printf:

QString str;
printf("%s\n", str.toLatin1().constData());
fflusg(stdout);

qDebug() << "hello world";
