QProcess...what's wrong

[nupul]

I just can't get the output of "GNU locate" onto the Textedit Widget. Infact, the QByteArray is being detected empty!!

if i start the process in startDetached(...) I can see the output on my terminal! but using only start(...) I can't seem to get it working!!

Help pls...

#include <QApplication>
#include <QString>
#include <QWidget>
#include <QLabel>
#include <QProcess>
#include <QTextEdit>
#include <QTextStream>
#include <QByteArray>
 
int main(int argc,char *argv[])
{
        QApplication app(argc,argv);
 
        QWidget *w=new QWidget(0);
 
        w->setGeometry(0,0,300,300);
 
        QTextEdit *output=new QTextEdit(w);
 
        QProcess locate;
        locate.setReadChannel(QProcess::StandardOutput);
        locate.start("locate *.mymenu");
 
        QByteArray results=locate.readAllStandardOutput(); //readAll() too didn't work
 
        if(results.isEmpty())
        {
                w->setWindowTitle("Sorry...doesn't work!");
        }
 
        QTextStream data(&results);
 
        output->setPlainText(data.readAll());
 
        w->show();
 
        return app.exec();
}

        QByteArray results=locate.readAllStandardOutput(); //readAll() too didn't work

        if(results.isEmpty())
        {

        }

        QTextStream data(&results);

        output->setPlainText(data.readAll());

        w->show();

        return app.exec();
}

To copy to clipboard, switch view to plain text mode 

Thanks
