Hello everybody,

I have a similar problem as Kelly stated about ClickToFocus too. I am
working on a special WM project and which based from fvwm. I want this
WM only have ClickToFocus active and want to change focus whatever user
click (any combination of keystroke with mouse button click) to any of
window (which include title bar, button, border, application widget,
... etc.).

I have been updated my source based on the archive Mar 24, 1999 which
Dominik Vogt suggest. I have modified the file event.c in the function
HandleButtonPress() and comment out the line to check for modifier key.
But I still can not make to above requirement work.

For example, I have two xterm (let's call them xtermA and xtermB)
running. First, xtermA have the focus. Then, press shift plus first
mouse button click on xtermB (try not on border and title bar). The
xtermB won't get the focus on the action. And then, try just first
mouse button click to xtermB again. This time the xtermB have the
focus. Would anyone explain how the ClickToFocus work in fvwm in
detail? What will be the event flow from X server to a window itself to
make it focus?

Many thanks in advance!!
