QProcess: how to suppress the console window on windows?
I use the following code to start an external mediaplayer and control it (for pause/start/stop):
@ video_process = new QProcess(this);
arguments << "--video-on-top" << "-I" << "rc";
if(video_process->waitForStarted(5000) == false)
QMessageBox messagewindow(QMessageBox::Critical, "Error", "Unable to start VLC mediaplayer.\n"
"Check your installation of VLC.\n"
"Also, check if VLC is present in the PATH evironment variable.");
It works great on Linux and it's exactly what I need. I can load, start, stop and pause media and get info about the position (time left).
The problem is, it does not work on Windows. When I run this code, for some strange reason Windows opens a console.
This creates two problems:
- It's ugly to see another unused window.
- More urgent, the responses of my commands will end up in the console window instead of my application, so communication is lost :-(
My question is, how do I use QProcess on windows without opening a console window?
Exactly as you did.
Unfortunately see what happens when you run this command in the windows command prompt - yup, it opens another one. It seems that vlc on Windows is just built that way (a very not nice way that is), but it's not a problem with Qt or QProcess.
Thanks Chris for your quick and helpfull reply.
This is a pitty for my project :-(
Maybe there's a Windows specific switch or something. Try asking on the "vlc forum":https://forum.videolan.org/
