773526 - [UIEvents-key] ::ImmGetVirtualKey() always returns VK_PROCESSKEY on Win7

Status: RESOLVED INVALID

(Core :: Widget: Win32, defect, P3)

Description

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

When I testing, I realized this fact.

::ImmGetVirtualKey() always returns VK_PROCESSKEY on my Win7 system. It doesn't depend on IME. When I can reproduce this with either IMM based IME or TSF based TIP.

I guess that the API doesn't work after Vista because the IMM backend has been removed and emulated by TSF.

Kato-san, Kimura-san, do you know something about this?

See MSDN (http://msdn.microsoft.com/en-us/library/windows/desktop/dd318570%28v=vs.85%29.aspx).

Return value

If TranslateMessage has been called by the application, ImmGetVirtualKey returns VK_PROCESSKEY; otherwise, it returns the virtual key.

Can we use LPARAM of window proc instead of.

Also, windows vista doesn't remove imm backend yet.  IME2007 and IME2010 have TSF backend  and IMM emulation layer by TSF.

Oh, thanks. I misunderstood the document. I'll post a patch soon.

Now, we need to dispatch keydown and keyup events with keyCode=229 and key="Process" if they are processed by IME. So, we don't need to know raw key code values anymore.
