Well no. There are certain things that need to steal focus, like
dialog windows for example. Basically what I'm doing is writing a baby
window manager for a suite of applications that lives inside a of
fully fledged window manager. I've got about 30 or 40 applications,
many of which run fullscreen all the time. And I need a way to shuffle
them around, bring some to the top, minimize, etc, all programatically.
Now, when the window is minimized to begin with, my present_window()
function *will* present the window and the window *does* steal focus,
in either RHEL4 or RHEL5. You're saying you consider that to be a bug?
I'm not trying to steal focus in the sense of "my application requires
attention and I'm stealing focus from some other application that the
user is interacting with." What I'm doing is more along the lines of
"the user has requested that window X should come to the front and
have focus, right now." And the window manager is denying the user's
explicit request because it comes in the form of my function call and
not the accepted "user clicks on taskbar item" workflow.

So there really is nothing I can do at the Xlib level to fix this?
What if I set the window to keepabove, then change it back to not-
keepabove after it's been raised. That might have the effect of
bringing the window to the top of the stack, at least. I know at least
that even though the window doesn't raise in RHEL5, it *does* get
keyboard focus because the window manager can't mess with my
I believe that this is due to the fact that XSetInputFocus requests
are unconditionally granted by the XServer, regardless of the wishes
of the WM. ( Read more here: http://lwn.net/Articles/148092/ )
Are there really no better suggestions?
