Re: [TCLCORE] Customers with "Bengali" as keyboard input language

Hi Jan,

I looked into the latest trunk and it seems it already contains handling for WM_UNICHAR and introduces a new "send_event" value of "-3" in the "XKeyEvent" structure to signal this case. I see no reason why this should not work for Bengali.

In 8.4 there is only the code path for Windows 2000 multi-lingal IME input, where xkey.trans_chars[] already contains a UNICODE char. This is signaled by "send_event" value "-2".

8.4 vs. 8.6:
We can't migrate to 8.6 easily, so I patched the 8.4 to use wide character function for message retrieval and then used the Windows 2000 codepath to deliver the received unicode characters through the " XKeyEvent" structure with "send_event" set to "-2".

It works! I am afraid of side-effects though, due to using GetMessageW() and DispatchMessageW() which may affect other messages as well.

For the moment our UI seems to work normally, which is a good for a first shot.

Robert.

Do we have a chance of doing this ourselfs in our 8.4 code base?

In the current trunk (Tcl/Tk 8.6.x code-base) allmost all Win32 API calls already use the *W functions directly. If some places are not correct, and you happen to have (or willing to create) a patch for it, I will be happy to review and test it. If it works fine, I will be happy to make sure that Tcl/Tk 8.6.3 works with Bengali out of the box.

Tcl/Tk 8.4 is no longer supported, so don't expect any help here from us. But submitted patches against trunk will be happily considered for inclusion.
