The part of the Button looks so:
Could anyone help me, with my Problem ?Code:void MainWindow::on_applypush_clicked() { QStringList combo; combo << ui->comboBox->currentText(); QProcess *process = new QProcess(this); process->start("./sbin/xicon", combo); }
You can also leave out the . -mark from QT-code.
And one more thing, you are running your QT-app as user, not as root are you?

I'd start with the path to the binary. As pointed out above. the "." makes a difference.
With a path starting with ".", it becomes a relative path, relative to whatever the Qt application has as current working directory.
So, remove that and try again.

Hi,
RE. the script: You have whitelisted zicon in /etc/sudoers.d (and ran update-sudoers afterwards)? If you haven't, sudo's gonna be waiting asking for a password. And depending on the way you've written the could-be sudoers file, running "sudo zicon" as root will make sudo do absolutely nothing

I think it is related to the path setting / or exec bits. You may verify by process->error() (or capture the error() signal) . If It is QProcess::FailedToStart , then it was not able to start the program.

Well, i think, that the Problem is from the other side....
I've the directory "Data" with all my realated Files in Subdirectories, but the Problem seems to be, that the Files are after the installation gone ?!? I don`t know how,but they are gone....*gg
My "Sudoers File" -->gone
My "scripts"-->gone.
Such Problems on so a simple thing....can´t believe it..
I´m searching over and over....

...got it....it was a sudoers problem...thank you qwerty12 and all the others who helped me !
Now, is there a way to reboot the system with a Clicked Signal....?
I mean this solution :
should not be the best one....
Or do I have to make a shellscript with an simple " reboot" inside. (ofcourse, with sudo rights)
