I'm trying to find a bug causing emacs keys not working properly in evolution.
I suspect that the key binding table becomes destroyed of some reason,
as the key table lookup may first succeed, and later fail. I don't yet
know which
package to suspect.
***************************************************************
My question: Is there a simple way to check/verify/print the structure
of the keybinding table?
***************************************************************
Description follows:
In 50% of the invocations of evolution it works for the first editor invocation
of the editor, but not the following.
I'm using sources from gtk+-2.6.4, gtkhtml-3.6.1 and evolution 2.2.1.1 for now.
The key bindings are read from a file keybindingsrc.emacs with gtk_rc_parse
and lands into structure html_class->emacs_bindings and are interpreted in
the following way:
gtk_binding_set_activate (html_class->emacs_bindings, event->keyval,
event->state, GTK_OBJECT (widget));
This results in a call to binding_ht_lookup_entry where the follwing fails:
<<<<<
lookup_entry.keyval = keyval;
lookup_entry.modifiers = modifiers;
entry = g_hash_table_lookup (binding_entry_hash_table, &lookup_entry);
/* added debug print roland orre neurologic se */
if (entry) {
printf("gtk: entry found for keyval %d\n", keyval);
printf("gtk: modifiers = %lx\n",modifiers);
}
else {
printf("gtk: entry was not found for keyval %d \n",keyval);
printf("gtk: modifiers = %lx\n",modifiers);
}
>>>>>
The key binding hash table is pointing to the same address all the time,
a table where lookup of the key has first succeded with lookup and
at later editor invocation failed. I have turned off passing to parent class.
Best regards
