Hi i have a button on my gui. When ever am clicking button, i need to set focus to already playing VLC media player.
So am unable to figure it out. how to set focus to different application by button click.

Hi
You cannot do that with Qt as far as I know. You must use your platforms API
to find the window and set focus to it.
Do note that Windows 10 might not allow you to do so if VLC players is not in foreground.

Can I ask what you try to do ? / what task is.

Hi mrji, Actually i want to handle VLC media player(start,stop,pause) through Qt application.
When i click start button in Qt application it should replicate in VLC player. same as for stop and pause.
Both VLC and Qt application will running at same. When i click start button in QT application, i need to set focus to VLC player and start playing music.

Hi
You will have to use Windows API for that. We cannot just all setFoucs in other app with pure Qt.

However, there might be a better way
