[Solved] QObject::connect: Incompatible sender/receiver arguments

[luca72]

Hello i have write this:
@void Widget::leggo_output(QProcess &p){
QApplication::processEvents();
QString mess = p.readAllStandardOutput();
ui->plainTextEdit->setPlainText(mess);
QApplication::processEvents();

}

void Widget::leggo_errore(QProcess &p){
QApplication::processEvents();
QString mess_err = p.readAllStandardError();
ui->plainTextEdit->setPlainText(mess_err);
QApplication::processEvents();
}

void Widget::masterizzo(){
QProcess *p = new QProcess;
connect(p,SIGNAL(readyReadStandardOutput()),this,SLOT(leggo_output(QProcess&)));
connect(p,SIGNAL(readyReadStandardError()),this,SLOT(leggo_errore(QProcess&)));
p->start("xbox");
}@

I get this error:
QObject::connect: Incompatible sender/receiver arguments
QProcess::readyReadStandardOutput() --> Widget::leggo_output(QProcess&)
QObject::connect: Incompatible sender/receiver arguments
QProcess::readyReadStandardError() --> Widget::leggo_errore(QProcess&)
what is wrong?

Thanks

Luca
