Hello !

I'm having a hard time figuring how to use fltk and sensekey. I tried all
the examples i found but none worked. Is sensekey broken ? I'm using csound
5.10.1 on debian. 

Here is the last code i tried 




; Select audio/midi flags here according to platform
; Audio out   Audio in    No messages
;-odac           -iadc     -d     ;;;RT audio I/O
; For Non-realtime ouput leave only the line below:
; -o FLpanel-sensekey.wav -W ;;; for file output any platform
-odac -b512 -B1024 -d 



; Example by Johnathan Murphy

  sr	    =  44100
  ksmps	    =  1
  nchnls    =  2


	; ikbdcapture flag set to 1
  ikey	    init      1 		
 
	    FLpanel   "sensekey", 740, 340, 100, 250, 2, ikey
  gkasc, giasc	FLbutBank	2, 16, 8, 700, 300, 20, 20, -1
	    FLpanelEnd
	    FLrun

    instr 1

  kkey	    sensekey
  kprint    changed   kkey
	    FLsetVal  kprint, kkey, giasc

    endin

I use sensekey all the time with MacCsound, Mac-PPC OS X10.4.11 and earlier,
csound 5.08 and earlier.

It's fine for reporting key-down, but I cannot use it for determining
key-up. 

The following code works for me:

instr 5            ;Poll for computer-key pressed; set globals indicating
what row and key it is.
ilowestLegitValue        init        33                ;corresponds to "!"
ihighestLegitValue    init        126                ;corresponds to "~"
kKey, kkeydown            sensekey            ;get any pressed keyboard key
gkKeyBoardRow    =        -1                ;defaults to -1 if no key
pressed

if( ilowestLegitValue<=kKey && kKey<=ihighestLegitValue && kkeydown==1) then
    gkKeyBoardRow        table    kKey-ilowestLegitValue, 200        ;lookup
row number in table 200
    gkKeyNumber        table    kKey-ilowestLegitValue, 201        ;lookup
key number in table 201
    gkCurrentKey        =        kKey
endif
if(kkeydown!=1)then
    gkKeyBoardRow        =    -1
    gkKeyNumber        =    -1
    gkCurrentKey        =    -1
endif

endin

Thanks for your help but unfortunately i still get nothing.

Can someone tell me if te examples provided in the doc works on their system



; Select audio/midi flags here according to platform
; Audio out   Audio in    No messages
-odac         ; -iadc     -d     ;;;RT audio I/O
; For Non-realtime ouput leave only the line below:
; -o FLpanel-sensekey2.wav -W ;;; for file output any platform


sr =  48000
ksmps =  32
nchnls =  1
; Example by Istvan Varga
; if the FLTK opcodes are commented out, sensekey will read keyboard
; events from stdin
        FLpanel "", 150, 50, 100, 100, 0, 1
        FLlabel 18, 10, 1, 0, 0, 0
        FLgroup "Keyboard Input", 150, 50, 0, 0, 0
        FLgroupEnd
        FLpanelEnd

        FLrun

        instr 1

ktrig1 init 1
ktrig2 init 1
nxtKey1:
k1, k2 sensekey
        if (k1 != -1 || k2 != 0) then
        printf "Key code = %02X, state = %d\n", ktrig1, k1, k2
ktrig1 =  3 - ktrig1
        kgoto nxtKey1
        endif
nxtKey2:
k3 sensekey
        if (k3 != -1) then
        printf "Character = '%c'\n", ktrig2, k3
ktrig2 =  3 - ktrig2
        kgoto nxtKey2
        endif

        endin
