I have a app A. In A, have two button : Open and CLose.

When I click Open button, it show other App - for example, name :B.
When I click Close button, my app send "CTRL+Q" event to close B app.

I write code by Qt and VS2010. I use QProcess to show B. But I don't want to use QProcess::kill or close() to close B app. I want to send "CTRL+Q"event to close B app because I have some code in B app what free memory. Thanks for helping!

P/s: In B App , I wrote if you press CTRL+Q , app close.

Resolve : I don't find how to send "CTRL+Q" event but if you close other app, you should use "QProcess::terminate()". Don't use close or kill because it kill your other app.

GUI applications on Windows, OS X and X 11 platforms can be terminated by sending them a platform-specific quit message (on X11 it's not called quit). This is done by `QProcess::terminate`. The `Ctrl-Q` shortcut is application-specific, you can't know if it might be language-specific, etc. – Kuba hasn't forgotten Monica Aug 02 '14 at 16:35
