Well, it wouldn't, but this is 'int Fl::event_key()', which doesn't
return UTF-8 anyway. The doc says it returns a 'keycode', but doesn't
really define what that is. When I type on a zhuyin keymap, I get the
qwerty keys, and when I use the OS X character pallette apparently
event_key() doesn't understand it at all... I get a FL_KEYDOWN and
FL_KEYUP, but the event_key retains the previous value.
I've gotten sort of random stuff out of event_key(), it can give some
confusing results on OS X when the keyboard has been remapped.
Interestingly, when I switch from zhuyin back to latin, I get this msg
from the OS:
2011-03-25 20:57:08.464 flbug[72227:903] Warning - conversion from 64
bit to 32 bit integral value requested within NSPortCoder, but the 64
bit value 9223372036854775807 cannot be represented by a 32 bit value
I modified it to include Fl::event_text(), and utf8 for that part
seems to work fine:
const char *
show_event_info(int ev)
{
static char buf[1024];
switch (ev) {
case FL_PUSH: case FL_DRAG: case FL_RELEASE: case FL_MOVE:
case FL_MOUSEWHEEL:
snprintf(buf, sizeof buf, "(%d, %d)", Fl::event_x(), Fl::event_y());
break;
case FL_KEYDOWN: case FL_KEYUP:
// Don't bother with Fl::event_length() because 'buf' isn't returned
// with an explicit length.
snprintf(buf, sizeof buf, "%s (\"%s\")",
show_key(Fl::event_key()), Fl::event_text());
break;
default:
return "unknown";
break;
}
return buf;
}
