I don't use many gtk applications, just gnome-terminal and sometimes
nautilus.  this affects both.  Emacs and xterm (not gtk) are unaffected.

I use dead_stroke in a keymap table file that I pass to xmodmap and I
don't manage to obtain any visible effect.

to reproduce the bug, I used this keymap table file, »
clear Lock
keycode 66 = Multi_key
keycode 48 = dead_stroke
« and activate it with xmodmap.

hitting the key associated to dead_stroke followed by l should produce
ł (small L with stroke) but gives l (small L).  compose slash l works
correctly.

also dead_breve does not work.
other dead keys like dead_macron, dead_acute and dead_breve do work with
this method.

I observe the same behaviour also on maemo, both on os2008 (using xmodmap)
and meamo5, where I don't use xmodmap but setxkbmap.

This is because GTK+ uses its own composition tables and extends them in
its own way.

If you want to use the X input method in an application, you can
right-click, select “Input method”, then “X input method”.

You can also select it by setting GTK_IM_MODULE=xim in the environment.

Cheers,

no, I actually really want to use GTK+'s own input method...  can you
point me to references on how to use them?  (I am a bit internet-impaired
at the moment, laptop was stolen, I can use email but home browsing
is more or less limited to my maemo5 device)  what I suspect is that
there's a problem with dead_stroke and dead_breve, and I base this on:

1) xmodmap manages to alter GTK+ composition tables for all dead keys
   except dead_stroke and dead_breve.

2) on maemo5, which is AFAIU GTK+ based, I am using its own keyboard
   definition table and dead_stroke and dead_breve do not work.

to verify my suspicion I want to use GTK+'s native input method on my
old desktop system and check if there I do manage to get dead_stroke
and dead_breve to work.

hi here,

I'm looking for the proper gtk+ way to define and set keyboard layouts.
is it through usage of `setxkbmap`?  this is what one uses on Maemo so
I assume it is the way to go.

well, also using setxkbmap dead_stroke does not work.

in the us(mac) layout dead_stroke is associated to the 'S' key, with
shift and right alt modifiers.

after `setxkbmap "us(mac)"` the behaviour I get is exactly as what I
get when I alter the keyboard layout using xmodmap, namely:

* gnome-terminal: dead_stroke does not compose with following key
* xev shows the KeyPress event for dead_stroke
* uxterm: dead_stroke correctly composes ħđøł

I've googled in a few different sessions and I don't find anything
looking like composition tables for gtk+ anywhere, except possibly this
very bug report.
