Parse IDCMP_EXTENDEDKEYBOARD through WM_HANDLEINPUT ?

Hi,

I've opened a ReAction window which has (among others) the IDCMP_RAWKEY and IDCMP_EXTENDEDKEYBOARD flags set.

Whenever I'm signalled that something has happened with the window I call its WM_HANDLEINPUT method. This is what happens:

When a normal key is pressed the method's result has got the WMHI_RAWKEY bit set and I can parse the raw key as expected. The next result I get is WMHI_LASTMSG.

However, when a multimedia key is pressed I'm still signalled but the very first WM_HANDLEINPUT returns WMHI_LASTMSG. Interestingly the int16 pointed to by wmh_Code contains 0x4000 in this case which matches IMSGCODE_INTUIRAWKEYDATA.

A coincidence?

Could be because I can't squeeze any more information out of it. Even GetAttrs(WinObj, WINDOW_InputEvent) doesn't give me any valid data. I guess that's to be expected. I haven't received a WMHI_RAWKEY, so why should it?

So ... am I missing something?

Pressing a multimedia key causes a signal to be sent but WM_HANDLEINPUT doesn't give me anything back?

Any help appreciated. :)

I guess you cannot expect anything from WM_HANDLEINPUT because window.class neither knows nor handles IDCMP_EXTENDEDKEYBOARD (yet). Your only choice probably is WINDOW_IDCMPHook / WINDOW_IDCMPHookBits with a function which extracts the required values from the IntuiMessage and somehow forwards them to your main program (for example using the h_Data pointer).

Aah, thanks a lot! I was looking for a way to handle IDCMP_EXTENDEDKEYBOARD myself but still use WM_HANDLEINPUT for all the other IDCMP flags. Didn't know about this IDCMP hook. Thanks for pointing me to it! :)

@TomSoniq

The WM_HANDLEINPUT method does not (and will not, I was told) support all IDCMP events, so as Thomas says, WINDOW_IDCMPHook is the way to go.
