Hi all,
Reading the recent post by Artur, I feel obliged to share what I have been doing to support IME in wxWidgets.
My main interest is to support IME in wxStyledTextCtrl, since the lack of support for IME renders all the wxSTC-based text editors inappropriate for editing Japanese text.
The following platforms are currently supported:
MSW (via the classic IMM32), OSX/Cocoa, and GTK.
The work-in-progress branch is available here:
https://github.com/minoki/wxWidgets/commits/experimental-ime-support
(Note: This branch is subject to force-push and don't rely on it.)
Demo:
https://vimeo.com/211472594
What I have done so far:
- Define some classes and events to handle IME. (Though the interface is rather messy and needs to be redesigned)
- Implement the IME-related events for each platform (MSW/OSX/GTK).
- Let wxSTC handle IME through the new API. (This is relatively easy because the recent Scintilla has support for 'inline IME')
What remains to be done:
- Advanced IME support.
- Let wxRichTextCtrl handle IME.
I have little time to work on this, but I hope that some functionality could be merged in before wxWidgets 3.2.
Regards,
ARATA Mizuki

This is very nice, thanks! I'm afraid I can't really help much with this,
but it would be great to discuss the final API here if possible.

Sorry, what does this mean?
AM> - Let wxRichTextCtrl handle IME.
Is it too naive to hope that IME can be completely hidden from the
application-level code, i.e. that the application would just receive the
correct wxEVT_CHAR(S?) events?

Sure, this would be definitely very useful.
Thanks again,
VZ

Dear Mizuki, Dear all,
I've checked the changes in the experimental IME branch.
They are similar to the patch I intended to submit, but they a more
complete and better platform-independcy-wise.
So instead of submitting the patch, I'd rather integrate/test the
changes made in this IME branch.
I'm just not sure whether it is best to wait until the
final/intermediate version is merged to trunk/master.
Regards,
Artur Sochirca

Hello Vadim,
Do you mean a PR made for the changes from "
experimental-ime-support"
branch?
This is to be done by the author, right?
Regards,
Artur

Thank you for your hard works!
There seems to be some minor bugs but it appears good working.
ime caret position implemented Demo On wxGtk:
https://youtu.be/7sFAz6BTUGw
I am playing with it but I have found a inconvinient thing.
Is it possible to move or delegate OnTextInput event in stc.cpp.in to scintillaWX.cpp?
report bugs: X bad, O good
back-space Handling while composiong indicator attribute
wxMsw X O
wxGtk O X
cheers to you!

Woud you please take a review at this patch?
Demo: https://youtu.be/w8XNc9EFhdk
here are changed:
1. cursor position has been implemented.
- add charaacter one by one instead segment of characters.
2. SC_INDICATOR_BLOCK for background color attribute has been introduced.
- The problem of one line style only has been fixed.
3. candidate window positon has been fixed.
4. recording macro is escaped.
Now I am struggling with scintilla ime on wxWin .
very troublesome!

It appears for VK_BACK and VK_ESCAPE to slip out of hands of IME.
They should make comosition to be canceled,
but no ime event happens.
their behavior differs from notepad, wordpad, or SciTE.

too many dirty patched for Demonstration of inline ime on wxMSW.
demo : https://youtu.be/dtWGqf3Zhe0

Hi,
Could you please submit it as a pull request to GitHub so that we could
check that the patch passes CI checks?
Thanks in advance,

I think this is too early stage to see if it passes through CI checks.
It needs far more to be discussed, especially on wxMSW.
I hope Mizuki sang, who has built ime wxevent system, arrange this.
I think it is not me that pull the request but him.

solved the problem about VK_BACK on japanese ime.
it sends WM_IME_COMPOSITION but neither GCS_COMPSTR nor GCS_RESULTSTR.
if ((lParam & GCS_COMPSTR) || ((wParam == 0) && (lParam == 0))) // VK_BACK

I need more information on wxTextInput messages.
I can not understand what they are designed for.
They seem to be useless for implementing reconvert string feature.
