How can I write a hook to activate when any emacs frame is raised/focused?

Under Win32, each emacs frame shows up as a different window when Alt-tabbing, which makes sense. However, when I select my main editing window, I'd also like my speedbar frame to auto-raise along with it.

Writing a function to raise all frames (or even all currently NOT visible frames) is relatively trivial, but I can't figure out hook to use, or indeed if there's even a hook that's possible to use at all.

So, if I click or alt-tab to any of my emacs frames, a hook should be run to call my function that raises ALL frames. Any help?

I found a hook you can use with.

server-visit-hook is a variable defined in `server.el'.
Original value was nil

Documentation:
Hook run when visiting a file for the Emacs server.

You can customize this variable.

When you find a file with Emacs server or emacsclient, this hook will invoked. you can use this hook to do something need.

The closest I can find in GNU Emacs is the switch-frame event, but it's only generated when a different Emacs frame is focused, not when you switch to a non-Emacs window and then back to the same frame.

This is the sort of things that a good enough window manager should do, with a bit of cooperation from Emacs (for example using window titles to figure out what the speedbar frame is).

Under Windows, you should be able to use AutoHotKey's WinWaitActive command.

It doesn't seem that GNU emacs has any such functionality.

Xemacs has select-frame-hook and map-frame-hook. There is also the variable auto-raise-frame, but, not in GNU emacs.

See http://www.xemacs.org/Documentation/beta/html/lispref_40.html#SEC526 for some ideas if you feel like improving emacs.
