How execute a script in a Qt aplication?

[Gerard]

yes yes, the script is in /opt/

[wysota]

But what the current working directory is? Did you explicitly set it to /opt? What happens if you call the script as /opt/script.sh instead of ./script.sh?

[Gerard]

If i put next code:

void proves::execapp(){

QStringList argo,list;
argo.clear();
list.clear();

QProcess * exec;
exec =new QProcess(this);
list <<"PATH=/usr/bin/:/bin/:/opt/:/opt/p/:";
exec->setEnvironment(list);
exec->start("/opt/calibrate.sh");

}

the results are worse, don't appear new PIDs

[wysota]

You forgot to start sh.

exec->start("/bin/sh", QStringList() << "/opt/calibrate.sh");

exec->start("/bin/sh", QStringList() << "/opt/calibrate.sh");

To copy to clipboard, switch view to plain text mode

I found the solution....

the code was correct in all cases.

in the code i added this line:

exec->setProcessChannelMode(QProcess::ForwardedChannels );

Then, when i press the button, in the terminal out the next line:

TS_OPEN: not such file name.

TS_OPEN is internal function of TS_LIB, libray of touchScreen control. This function need the specific device of touchScreen.

To solve this, i added the variable TSLIB_TSDEVICE in environment ---> QStringList list <<"PATH=/opt:/opt/p:/usr/bin:/bin:/sbin:/usr/local/bin:/usr/etc:"<<"TSLIB_TSDEVICE=/dev/input/event1";

that's all

thanks for your time
