hai,
In my application, i am using combo box. In that combo box 8 channels will be their. So when we select a channel1 Qprocess will run C executable file and i will read data from that process.
I am using this type of code for running the C code after selecting a channel.
program = "/home/Testing/test";
arguments<<"0xff"<<"0xbb"<<"0xcc"<<"0xdd"<<"0xaa"<<"0xcd"<<"0xab"<<"0xdf";
process =new QProcess(this);
process->setReadChannel(QProcess::StandardOutput);
process->start(program,arguments);
process->waitForFinished();
QByteArray b1=process->readAllStandardOutput();
ui1->textEdit->clear();
QString command(b1);
ui1->textEdit->setText(command);
process->closeReadChannel(QProcess::StandardOutput);
process->kill();
b1.clear();
My problem is when i select channel1, channel 1 data is displayed in text edit.
If i select channel 2, then both channel 1 and channel 2 is displaying. i.e.,
QByteArray b1=process->readAllStandardOutput(); this function is reading both previous and present channel data.
But i need only selected channel data. So how can i clear the previous channel data.
Its very important to me. So please give your valuable suggestions for this post.
Thank you…..
