BTW, fl_eventnames appears to be undefined. I see it in commented-out
debug prints, but can't find a definition anywhere.
I actually have a small utility library that has a 'const char
*show_event(int evt);' function that's basically the same, only safer,
since it won't segfault on a bad input. Since it's obviously a useful
function, how about adding it to the Fl namespace or something?
Here's mine:
const char *
show_event(int ev)
{
const char *e = "unknown";
switch (ev) {
case FL_NO_EVENT: e = "nothing"; break;
case FL_PUSH: e = "push"; break;
case FL_DRAG: e = "drag"; break;
case FL_RELEASE: e = "release"; break;
case FL_MOVE: e = "move"; break;
case FL_MOUSEWHEEL: e = "mousewheel"; break;
case FL_ENTER: e = "enter"; break;
case FL_LEAVE: e = "leave"; break;
case FL_FOCUS: e = "focus"; break;
case FL_UNFOCUS: e = "unfocus"; break;
case FL_KEYDOWN: e = "keydown"; break;
case FL_KEYUP: e = "keyup"; break;
case FL_SHORTCUT: e = "shortcut"; break;
case FL_DEACTIVATE: e = "deactivate"; break;
case FL_ACTIVATE: e = "activate"; break;
case FL_HIDE: e = "hide"; break;
case FL_SHOW: e = "show"; break;
}
return e;
}
In fact, here are some more bonus ones:
const char *
show_key(int key)
{
static char buf[32];
if (isprint(key))
sprintf(buf, "'%c'", key);
else if (isprint(key < FL_KP_Last && key - FL_KP))
sprintf(buf, "kp-%c", key - FL_KP);
else if (isprint(FL_F <= key && key < FL_F_Last))
sprintf(buf, "fn-%d", key - FL_F);
else {
const char *e = "unknown";
#define K(KEY, STR) case FL_##KEY: e = #STR; break
switch (key) {
K(Escape, escape);
K(BackSpace, backspace);
K(Tab, tab);
K(Enter, enter);
K(Print, print);
K(Scroll_Lock, scroll_lock);
K(Pause, pause);
K(Insert, insert);
K(Home, home);
K(Page_Up, page_up);
K(Delete, delete);
K(End, end);
K(Page_Down, page_down);
K(Left, left);
K(Right, right);
K(Down, down);
K(Shift_L, shift_l);
K(Shift_R, shift_r);
K(Control_L, control_l);
K(Control_R, control_r);
K(Caps_Lock, caps_lock);
K(Alt_L, alt_l);
K(Alt_R, alt_r);
K(Meta_L, meta_l);
K(Meta_R, meta_r);
K(Menu, menu);
K(Num_Lock, num_lock);
K(KP_Enter, kp_enter);
#undef K
}
return e;
}
return buf;
}
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:
return show_key(Fl::event_key());
break;
default:
return "unknown";
break;
}
return buf;
}
const char *
show_damage(uchar d)
{
static char buf[1024];
memset(buf, '\0', sizeof buf);
if (d & FL_DAMAGE_ALL)
strcat(buf, "all, ");
if (d & FL_DAMAGE_CHILD)
strcat(buf, "child, ");

strcat(buf, "expose, ");

strcat(buf, "overlay, ");
if (d & FL_DAMAGE_USER1)
strcat(buf, "user1, ");
if (d & FL_DAMAGE_USER2)
strcat(buf, "user2, ");
sprintf(buf+strlen(buf), "(%d)", d);
buf[strlen(buf)] = '\0';
return buf;
}
const char *
show_widget(const Fl_Widget *w)
{
static char buf[127];
IRect r = rect(*w);
snprintf(buf, sizeof buf, "(%d %d %d %d) %s \"%s\" '%s'",
r.x, r.y, r.w, r.h,
typeid(*w).name(), w->label(), show_damage(w->damage()));
return buf;
}
