Hi all,
I'm just digging into kbswitch and have several questions (later).
The major issue: kbswitch affects all windows at once, while it should
change the input language only for the current (focused) window.
I assume that kbswitch must preserve the active window, so that it can
know where to apply changes, and to re-activate that window when done.
As I don't know what's already implemented, I wrote a simple test
program, using
GetForegroundWindow() to determine the active window (hwnd),
GetWindowThreadProcessId() to get the related process handle, and
GetKeyboardLayout() to get the keyboard/language handle (hkl).
Tested on WinXP and ReactOS, the output looks correct. The hkl seems to
be composed of two words (hi: language and low: layout), which are
always the same on ReactOS. On XP a different keyboard layout can be
used for a language, but I cannot decipher the resulting encoding of the
layout. As soon as I try to change the layout for a language on ReactOS,
kbswitch shows the *layout* name, not the *language* name.
Q: Can somebody try to find out how to convert a HKL into language and
layout id's and/or names? (see GetLayoutIDByHkl)
Q: Is kbswitch notified of focus changes, and if so: how?
Then above sequence can be used to identify the related thread's
setting, and update the tray icon and menu accordingly.
Q: Is every process/thread already assigned a *private* hkl?
If not, this feature must be implemented before further updates.
So much for now
DoDi
