Show window in Qt without stealing focus

I'm using the Qt library to show a slideshow on the second monitor when the user isn't using the second monitor. An example is the user playing a game in the first monitor and showing the slideshow in the second monitor.

The problem is that when I open a new window in Qt, it automatically steals the focus from the previous application. Is there any way to prevent this from happening?

Solution

  • It took me a while to find it but I found it: setAttribute(Qt::WA_ShowWithoutActivating);

    This forces the window not to activate. Even with the Qt::WindowStaysOnTopHint flag
