QProcess readyRead() and readReadStandardOutput signals not triggered in kde

[jemesa]

Maybe you are reading from the wrong channel? What is the current channel of the process?

is the default channel of the process, not changed, the code is exactly the one shown above. What I find strange is that it works on Linux distributions with gnome interface but not working on distributions with kde interface.

And what happens if you run xprop directly from the console? Do you get the output desired on both kde and gnome?

[jemesa]

Yes, it works with both gnome and kde, and when setting the QProcess channel for ForwardedChannels, the console output occurs in real time in both kde and gnome.

Are you sure the output goes to stdout and not stderr?

I tried changing the channel mode to MergedChannels and not solved.
