[Iup-users] Matrix -- responding to key presses?

[Jeremy Cowgar]

Hello.

I am wondering how can I respond to certian key presses? for instance, 
when not in an edit field, I want to be able respond to some simple key 
presses to take action on, such as when the user presses D or K or L. I 
want to do something. I am having problems getting those key presses. I 
figured I would just:

int myActionCallback (Ihandle *self, int ch, int lin, int col, int 
active, char *after)
{
  printf ("Ch=%i  lin=%i col=%i\n", ch, lin, col);
  switch (ch)
  {
    case 'D':
      do something
      return IUP_IGNORE;
   case 'K':
      do something else
      return IUP_IGNORE;
  }
  return IUP_DEFAULT;
}

IupSetCallback (myMatrix, "ACTION", (Icallback) myActionCallback);

But w/the above, it never seems as though my action callback function is 
called. Any thoughts?
