Author Topic: Issue a search box problem with using IME(Japanese, may be also Chinese)  (Read 934 times)

Hello,

I have a license of MC25 and I'm satisfied a playback quality of MC25 very much.
However, I hesitate to upgrade to MC27 because there is an issue which is important for me.

I often use the search box and most of my music tags are Japanese.
When I focus on the search box and turn on IME, the window of IME appears in the upper left corner of the desktop.

Do you have any future plans to resolve this issue?

Thanks.

I don't think MC does that.  Perhaps a setting somewhere else?

That's the standard Windows 10 IME.

When the user sets Focus to the Search box (or any other writable field), MC should tell Windows where to show the IME window in case the user invokes it (usually just below the textbox). I think this is the call:
https://docs.microsoft.com/en-us/windows/win32/api/imm/nf-imm-immsetcompositionwindow

Full API reference - I think you can also handle WinProc messages to detect when IME is opening and then set its position:
https://docs.microsoft.com/en-us/windows/win32/intl/input-method-manager-reference

@Terushu, does this work OK on MC25? If so, then it's a bug on MC27.

I think it's a issue of MC or the framework which is used for MC.
If the search box is created by windows general component, this issue will be not caused.

@zybex
Thanks.
This problem is also reproduced in the MC25.

MC is very popular in Japan so I want to fix this issue.

Check with windows updates for anything related to IME, etc.

On windows 10, Microsoft acknowledges, and has been trying to fix, a series of long-standing problems with IME and Japanese language support.

This has been going on since the introduction of Windows 10.

I hope that the program will handle and set a correct window position of IME by using ImmSetCompositionWindow, WndProc events, etc.
