Use QProcess to send out a command from your qt app?
xdotool key ctrl+V

Hello and welcome.

We understand that English may not be your first language, but this question is difficult to comprehend. Send a key press? Where? To a window within your Qt application, to another window in a different process with a UI?

@JonB Thank you very much. As you said, English is not my mother tongue. I want to make it like voice input, output speech recognition content at the cursor of any interface, the QT application has set the content to the clipboard, now I just need to paste the clipboard content to the cursor, but I can't find the paste function here.

@JoeCFD Thank you very much. That will solve my problem.

 QString cmd = "xdotool key ctrl+v";
 std::string str = cmd.toStdString();
 const char *cmd_cs= str.c_str();
 system(cmd_cs);

It will be better to use QProcess than low level system call. And also QProcess is cross-platform and system is not.

@JoeCFD Ok, thank you very much.

@pickupy
QProcess is cross-platform, but the way you do it with an OS command and xdotool is not. So it really doesn't matter how you invoke it....

@JonB OK
