Qt to linux terminal

thehilmisu

Hi everyone,

I wanted to write code and control the linux terminal from it's gui. Is there any chance to write command to terminal from
my project ?

Thanks in advance.

yes you can, but you can't see the result. This thing is independent from Qt. It's a function:

int system(const char*)

so for example, just type in the main() function (without Qt stuff)

@
int main()
{
system("mkdir ~/testDir");
}
@

[EDIT: code formatting, please wrap in @-tags, Volker]

But you I think you should use "QProcess":http://doc.trolltech.com/4.8-snapshot/qprocess.html . So you can read and write the console output.

Thank you for your answer. But i have a question again, how can i read the console output? I tried this but i could not see the output. I think i get this wrong =)

Thanks

@QProcess test;
test.start("ls", QStringList() << "-a");

test.write("ls");
test.closeWriteChannel();

QByteArray result = test.readAll();

qDebug()<<"gelen :"<<result;@

@test.waitForFinished();
qDebug() << "gelen :"<<test.readAllStandardOutput ();@

or use singal/slots:
@void error ( QProcess::ProcessError error )
void finished ( int exitCode, QProcess::ExitStatus exitStatus )
void readyReadStandardError ()
void readyReadStandardOutput ()
void started ()
void stateChanged ( QProcess::ProcessState newState )@

Take looke at the small "example":http://pastebin.com/xX0DLc5q here. I hope this helps you to understan how it works.

i've solved it thanks =) appearantly i have to put the "waitForFinished()" method.
