QProcess problem

[Mystical Groovy]

Hey all,
I have a strange problem with QProcess, I use QProcess and system command "whoami" to get current logged in user.

/** where "user" is the QLabel"**/
	QString whoamiCom = "/usr/bin/whoami"; //i also tried with just "whoami"
	QProcess *userproc = new QProcess(this);
	userproc->start(whoamiCom);
 
	user->setText(userproc->readAllStandardOutput());
        /**I also tried using this method:
          QByteArray result = userproc->readAll();
	user->setText(result); **/

/** where "user" is the QLabel"**/
	QString whoamiCom = "/usr/bin/whoami"; //i also tried with just "whoami"
	QProcess *userproc = new QProcess(this);
	userproc->start(whoamiCom);

	user->setText(userproc->readAllStandardOutput());
        /**I also tried using this method:
          QByteArray result = userproc->readAll();
	user->setText(result); **/

To copy to clipboard, switch view to plain text mode 

in anyway the program compiles and runs but nothing is parsed on "user" Label.

Please help, thx

You have to wait for the command to complete, before parsing the (in your case not yet printed) output. (see QProcess::waitForFinished())
(Unlike system() QProcess by nature is asynchronous: the command is executed and your program continues running.)
