Open desktop aplications using QProcess

I want to run an aplication using the information i got in aplication.desktop file. Per example for circus game i got the following information:

Name: "Circus"
Exec: "/usr/bin/single-instance /usr/bin/incrediblecircus"
Icon: "incrediblecircus"

How i use the QProcess to run /usr/bin/single-instance /usr/bin/incrediblecircus ?! Thanks :)

EDITED: It worked my bad :| but per example with maps it doesn't work:

Code:

 QProcess p;

    //p.start("/usr/bin/single-instance /usr/bin/incrediblecircus");

    p.start("/usr/bin/invoker --type=e /usr/bin/maps -u %U");

    p.waitForFinished(-1);

    QString output = p.readAllStandardOutput();

    qDebug() << output;

    qDebug() << "e:" + p.readAllStandardError();

The error:

The error:

The problem is that you are including the arguments in the program name. In the desktop file, the %U refers to a URI that is passed to the program when it is launched. If you want to launch Maps without any arguments, you should use

Code:

p.start("/usr/bin/invoker --type=e /usr/bin/maps");

If you want to pass an argument, you should use

Code:

QStringList args;

args << "-u" << your_argument;

p.start("/usr/bin/invoker --type=e /usr/bin/maps", args);

Thanks :)

I knew that i need to pass the arguments as a argument of the function start but my problem is that i don't know what to do with "/usr/bin/invoker --type=e"

thanks again :)

Re: Open desktop aplications using QProcess

I can't run notes app per example :s

QStringList args;
args << "-showWindow" << "%U";
p->start("/usr/bin/invoker --wait-term --delay=10 --type=m /usr/bin/notes", args);

and still doesn't work if not include the arguments :s

Can you help me?
