Well the code above doesn't compile; you can't assign KCompressionDevice around.
Also if you don't open the device, it won't open itself.
So
#include <KCompressionDevice>
#include <QDebug>
int main(int argc, char *argv) {
KCompressionDevice kgzip("hola.gz", KCompressionDevice::GZip);
kgzip.open(QIODevice::WriteOnly);
qDebug() << kgzip.isOpen();
kgzip.write(QString("hello World").toUtf8());
kgzip.close();
}
This does compile and creates a hola.gz file with hello Worlds as its contents.
Cheers,
Albert
