Re: [Iup-users] Fw: Re: Silence Alt-keys

[Antonio Scuri]

  The k_any calllback(s) is processed on WM_KEYDOWN and WM_SYSKEYDOWN
events. I made a simple test here and they are correctly returning 0 in the
WindowProc and not calling DefWindowProc when IUP_IGNORE is returned. In
both IUP_DEFAULT and IUP_IGNORE, Windows is playing the bell sound.

Best,
Scuri

Well, if nothing at all handles a specific keystroke, that is correct. However, 
I **did** handle it, just can't figure out how to say that I have.

[Iup-users] Fw: Re: Silence Alt-keys

[Pete Lomax via Iup-users]

Hi,
There is no problem with Alt-F1, or Alt-Home/End/Left/Right etc, but for Alt-X 
and Alt-, both IUP_DEFAULT and IUP_IGNORE sound the bell.

I should perhaps say this is probably a Windows-only problem. The code I am 
translating, from a win32-only gui, apparently solves the problem by 
(explicitly) returning 0 to WM_SYSCHAR, and not calling DefWindowProc(), and in 
fact I just changed it to (explicitly) carry on and invoke DefWindowProc() and 
lo and behold the bell came right back, just like it is on IUP.  Looking at the 
source code of IUP, in iupwinKeyEvent I see if (result == IUP_IGNORE) return 0; 
but I'm guessing that somehow fails to avoid carrying on into a DefWindowProc() 
somewhere?
 
Pete
