D16228: Raise window group together with group transient

graesslin added a comment.


  Ok, this is code which is ancient and something I have never even looked into. So I did some research and found in EWMH:
  
  > _NET_WM_STATE_MODAL indicates that this is a modal dialog box. If the WM_TRANSIENT_FOR hint is set to another toplevel window, the dialog is modal for that window; if WM_TRANSIENT_FOR is not set or set to the root window the dialog is modal for its window group.
  
  and:
  
  > Implementing enhanced support for application transient windows
  > 
  > If the WM_TRANSIENT_FOR property is set to None or Root window, the window should be treated as a transient for all other windows in the same group. It has been noted that this is a slight ICCCM violation, but as this behavior is pretty
  >  standard for many toolkits and window managers, and is extremely unlikely to break anything, it seems reasonable to document it as standard.
  
  So for all I wrote above I thought we were talking about groups.
  
  Now I have a question: what is a real-world example for a group transient?
