Opening KDE Konsole from Qt and sending a command
Ok, so I need to open a KDE linux terminal console from my Qt program, and this is what I've done to achieve that:
And this works fine.
The problem is: after I open the console (by the way, it has to be konsole, can't use any "console" function inside Qt), I need to pass a command to it, i.e. I want the console to execute "ps -al" or any other command.
I read a lot about QProcess and all that, and I tried to do the following:
I even tried to replace startDetached by start since I read that it could be a problem, but again the console that was opened didn't print anything.
Any ideas how I could open a console and send a command to that console (preferably using p1.startDetached instead of p1.start)?
Maybe you need to start BASH instead of konsole?
@bash -c "ps -al"@
@ QProcess process;
process.start("bash", QStringList()<<"-c"<<"ps -al");
Not sure, but perhaps Konsole exposes a DBUS interface you can use?
Yes, it turns out Konsole does! I found this:
qdbus org.kde.konsole /Sessions/$session_num sendText "$command"
qdbus org.kde.konsole /Sessions/$session_num sendText $'\n'
That means that you should also be able to do this directly from Qt itself, as Qt also supports DBUS directly.
I read that but I still have no clue how to do it :(
I did a quick QDBus code in the past, just to receive data from HAL when a device was removed:
this, SLOT(deviceRemoved(const QString)));
But I don't know how I could make use of that to send a command to a Konsole QApplication.
You can use: "callWithCallback":http://doc.qt.nokia.com/4.7-snapshot/qdbusconnection.html#callWithCallback
Why don't you just use something like this?
konsole --nofork --hold -e 'ls'
