QProcess emits readyRead too late!

[dynup]

Hi,

I wrote an appliaction for Android Debug Bridge (adb) to backup app data from an android device. But QProcess doesn't emit readRead signal, although adb gives an output:

class.h:

QProcess *process;

QProcess *process;

To copy to clipboard, switch view to plain text mode 

class.cpp:

process = new QProcess(this);
connect(process, SIGNAL(readyRead()), this, SLOT(readyRead()));
connect(process, SIGNAL(finished(int, QProcess::ExitStatus)), this, SLOT(finished(int, QProcess::ExitStatus)));
 
process->start("adb", QStringList() << "blah", QProcess::ReadOnly);

process = new QProcess(this);
connect(process, SIGNAL(readyRead()), this, SLOT(readyRead()));
connect(process, SIGNAL(finished(int, QProcess::ExitStatus)), this, SLOT(finished(int, QProcess::ExitStatus)));

process->start("adb", QStringList() << "blah", QProcess::ReadOnly);

To copy to clipboard, switch view to plain text mode 

(...)

void Class::readyRead() {
        qDebug() << "Class::readyRead()";
}

void Class::readyRead() {
        qDebug() << "Class::readyRead()";
}

To copy to clipboard, switch view to plain text mode 

In terminal the message is coming, than i confirm it on the device and than it's done. In QProcess the readRead signal is emitted after confirming on device! Why?

Thanks!

P.S.

connect(process, SIGNAL(readyReadStandardOutput), this, SLOT(readyRead()));

connect(process, SIGNAL(readyReadStandardOutput), this, SLOT(readyRead()));

To copy to clipboard, switch view to plain text mode 

or

process->start("adb", QStringList() << "blah", QProcess::ReadOnly | QIODevice::Text | QIODevice::Unbuffered);

process->start("adb", QStringList() << "blah", QProcess::ReadOnly | QIODevice::Text | QIODevice::Unbuffered);

To copy to clipboard, switch view to plain text mode 

doesn't work too!
