Yes; this is a good option, everywhere *except* Win64... On Win64, a long is
still only 32-bit (everyone else decided that in their 64-bit generation a long
would be 64-bits, but MS decided they needed to preserve the sizeof(long) ==

Probably depends on if you're setting the callback for the widget,
or the callback for the items.

Hi,
thanks for all the info! I really appreciate the response.
I tried your suggestions on my system: Debian 6.5 (64 bit), gcc-4.4.5, emacs
23, fltk-1.3.2
I tested the following:
eop op = (eop)fl_intptr_t(v); works fine
int i = (int)v; fails to compile (loss of precision) like you all said.

Greg's suggestion of using fl_intptr_t seems like the most portable option,
should work *everywh

Probably trying to sidestep the 'precision loss' error from the
newer compilers due to sizeof(void*) != sizeof(int).

Right -- probably a "precision loss" error during the void* -> int,
since sizeof(void*)==8 and sizeof(int)==4.
I think the best approach (in 1.3.x

Hi all,
Please excuse another newbie question.
I'm looking at storing an enum as user data in an Fl_Menu_Item user data. In
the callback, I want to access the enum.
I know that I can put the enum into user data as a string:
enum eop { task0=200, task2, task3};
Fl_Menu_Item menu = {
{ "thing 1",
10 matches
