Re: help needed: window focus bugs

[Elijah P Newren <newren math utah edu>]

Let me just take a minute and mention something related that is probably
of interest to an even wider group of application writers: It appears
the gtk+ support for _NET_WM_USER_TIME was incomplete.  If you have a
window open, and then use gtk_widget_hide and gtk_widget_show within
your app (or some equivalent functions, e.g. gtk_window_present can have
the same problem) then when the window opens the second time it could
appear without focus.  There is a new patch in bug 115650 that fixes
this issue.  This will certainly affect a _lot_ of applications.  It's a
fairly simple gtk+ patch, though.  I traced this down while trying to
figure out why certain gnome-applet windows weren't working w.r.t. focus
(and only some of the time, while others worked all the time...)

See the second patch in bug 150271, specifically the function
panel_gdk_x11_window_set_user_time that was added.  (The specific case
in that bug was that the user presses Alt+F2, which Metacity catches,
and Metacity has to forward that info to the panel, so the cases are
pretty similar.)
