[g-a-devel] generateKeyboardEvent Patch for Java Access Bridge

[Matt Wringe <mwringe gmail com>]

Hi, 

I am writing an java gnome app that needs to generate keyboard events
and I noticed that the generateKeyboardEvent method in the Java Access
Bridge is left blank. I have written a small patch that enables this
functionality and can be found attached to this email. If you prefer I
can open a bug and post this patch in bugzilla.

I have noticed a couple of other issues. It appears that
java-access-bridge/impl/org/GNOME/Bonobo/UnknownImpl.java is not utf-8
encoded and has special characters in it. This can cause problems with
some jvm's. For me to build the java access bridge, I either have to
remove the special characters or change the encoding to utf-8.

Also, I have noticed that there doesn't seem to be any way to get the
keycodes or keysyms for a specific character in the java access
bridge. I can though get keysyms through java gnome
(org.gnu.gdk.KeySymbol), but I don't can't figure out how to get
keycodes (other than hardcoding then). If I am not missing an obvious
way to do this, I may be willing to help implement this functionality
if you want.

If you have any questions please let me know.

Thanks,

Matt Wringe
