currently the sensekey opcode does not return anything for the arrow keys (up, down, left, right). i miss this a lot when i use the computer keyboard for live performances. in PD these values are caught by the object "keyname". i had a look in the pd sources; if i get it right, it is defined in line 342pp of https://github.com/pure-data/pure-data/blob/master/src/x_gui.c can there be a similar way to implement it in csound? thanks - |

Works for me on openSuSE. What are you seeing?

ah you are right ... it works in the terminal. so this is a csoundqt issue. i didn't expect this to be the reason. will move it to the csoundqt list. joachim On 29/01/19 17:03, john wrote: > Works for me on openSuSE.

Hi, John,
can you guess perhaps looking at this code (keyboardEventCallback in CsoundQt)
- why this kind of event like arrow keys are not caught (not my code and to
be honest, I don't understand it completely):
---
int CsoundEngine::keyEventCallback(void *userData,
void *p,
unsigned int type)
{
if (type != CSOUND_CALLBACK_KBD_EVENT && type != CSOUND_CALLBACK_KBD_TEXT)
{
return 1;
}
CsoundUserData *ud = (CsoundUserData *) userData;
// WidgetLayout *wl = (WidgetLayout *) ud->wl;
int *value = (int *) p;
int key = ud->csEngine->popKeyPressEvent();
if (key >= 0) {
*value = key;
// qDebug() << "Pressed: " << key;
}
else if (type & CSOUND_CALLBACK_KBD_EVENT) {
key = ud->csEngine->popKeyReleaseEvent();
if (key >= 0) {
*value = key | 0x10000;
// qDebug() << "Released: " << key;
}
}
return 0;
}
---
Thanks!

Hummm Seems to be in C++, a languge in which I am not very familiar.
First thought would be to uncomment the tracing statements to see what key
is being seen. Then I would need to know that the functions
ud->csEngine->popKeyPressEvent() and ud->csEngine->popKeyReleaseEvent()
were.

i am back with this, with two issues:
1. when i add the second output to sensekey, it does not any more return
for the arrow keys the numbers 68, 67, etc, but only 27 followed by 91.
can you try to change the example to
instr 1
k1, k2 sensekey
printk2 k1
endin
2. is there any way to return *one* number instead of a sequence?
otherwise i cannot see how to use the key information in code like
if kDown == 1 then
if kKey == 32 then
...
elseif kKey == 49 then
...
endif
endif
thanks -
joachim
