Code facelift included:
* Consistant indentation.
* Removal of all TABs (there were a bunch).
* Fit to 80 columns.
git-svn-id: https://svn.code.sf.net/p/freeglut/code/trunk@273 7f0cb862-5218-0410-a997-914c9d46530a
little changes to the code appearance.
* Fit the comments at the start of the file to fit 80 columns.
* Noted an unusual feature of the ATTRIB() macro.
* Added ATTRIB_VAL() macro which is really just two ATTRIB()s.
This lets us put things like {ATTRIB (GLX_RED_SIZE); ATTRIB (1);}
on one statement: {ATTRIB_VAL (GLX_RED_SIZE, 1);}.
I did this to preserve some of the layout of information while also
avoiding the nasty semi-visible ";" in the middle of a line of code.
And by putting the {braces} in the macro definition, I was able to
visually clean code of the form:
if (condition)
{
ATTRIB( X ); ATTRIB( 1 );
}
...rewriting as:
if (condition)
ATTRIB_VAL( X, 1 );
* Eliminated a bunch of say-nothing-new comments in fgChooseVisual().
* Combined some semi-useful comments into a block comment summarizing
a loop.

point of view (at least, insofar as: The original file's code was INCON-
SISTANT. I did not remove the "!= NULL" stuff, did not address the
shortest-branch-first issue for if-else statements, and left some rather
ugly "if (x) {... return y} /* else do this */ return NULL;" garbage.
This should, I think, be re-written as "if (x) return y; else return NULL;"
or even better, "ret = NULL; if (x) ret = y; return ret;"
In short, the code still has some issues, but I think that it's a bit
better.
(Oh, I also got rid of oustanding TABs.)

Fit most of the code to no more than 80 columns.
Raised some issues about completeness/correctness of trying to
decrement the max-window-ID (apparently in order to partially
recycle some window IDs to slightly slow the rate of growth of
window IDs). (I didn't change what the code does, though.)
The functionality of the code should be unchanged.

WIN32 code. Take abs(direction) as the number of ticks, and count it
down.
<stdlib.h> *should* be included by freeglut_internal.h, I think, so it
should be okay; otherwise add a suitable #include.

Now I've lost track of what I said I'd done. Something like:
* Fixed some issues with multiple wheels.
* Noted in comments some issues about other-than-3-real-buttons.
* Fixed formatting to fit 80 columns.
* Removed some BCPL/C++ style comments (//) that are not legal, and
which, if memory servers, are not even strictly legal when disabled
by preprocessor directives. E.g.,
#if 0
not-syntactically-valid-C
#endif
...is not legal. Though most cpp's will discard the bracketed material
completely before the main C compiler pass has a chance to analyze the
syntax. (MSVC++ and GCC both don't seem to mind the BCPL style comments
in plain C, but let's keep the sources clean, eh?)
* Fixed a problem that would have caused freeglut to report doubled
wheel events under XFree86.
Not tested other than compiling. Personally, I think that the interface
is inherently broken at this point unless you are willing to get user-
configuration. (Which would then solve the complaint that Steve had
about computing the tick-size on behalf of applications.) I.e., there
is NO WAY to know if we have the right buttons to start wheels at, or
if there are any buttons after the first wheel(s), etc. We just have to
guess---and if we are wrong, we can get varying degrees of brokeness.

So I've copied the way the game mode does it. It's not ideal but it works.
The glutGet() for the window border sizes will also have to be fixed at
some point.

It now correctly places the window in X11.
It now uses system dependant code for more efficient use of
windowing system calls.

I missed a few lines that went past 80 columns. (^&
Also made formatting more consistant.
Added a couple of XXX comments re. FreeBSD vs. general BSD #ifdef's.
git-svn-id: https://svn.code.sf.net/p/freeglut/code/trunk@264 7f0cb862-5218-0410-a997-914c9d46530a
* Fit lines to 80 columns. (It does get tiresome seeing long lines
forced to break by the right-hand border of windows...(^&)
* Eliminated say-nothing-new comments.
* Made formatting more consistant in spots.
* Eliminated some hard TAB characters.

numbers for OS releases corresponding to system headers.
I modified it to also work with NetBSD; I cannot confirm if it is safe with
any other systems, so it remains protected by a #if.

Added some new comments with XXX's where future attention seems profitable.

Re-tweaked some lines (mostly got rid of some TABs, but also resulted
in some changed indentation).
Reformatted a big comment to fit to 80 columns.
Removed bogus references to "Linux". (UNIX, and/or X11 were relavent,
and "UNIX/X11" was substituted for "Linux" in those places. This includes
UNIX-alike systems.)
git-svn-id: https://svn.code.sf.net/p/freeglut/code/trunk@259 7f0cb862-5218-0410-a997-914c9d46530a
Cleanup of fghGetConfig(). (One return statement, simpler code.)
Made glutSetOption() have a more consistant style---and also got its lines
to stay under 80 columns.
git-svn-id: https://svn.code.sf.net/p/freeglut/code/trunk@258 7f0cb862-5218-0410-a997-914c9d46530a
(I would have picked them up before, but wanted the bug-fix and
conversion-to-error-message changes to go in before I did more
superficial stuff.)
git-svn-id: https://svn.code.sf.net/p/freeglut/code/trunk@257 7f0cb862-5218-0410-a997-914c9d46530a
((a) || (b)) was defined to have value as:
(a) if (a) != 0
(b) if (a) == 0
...instead, it has value 0/1. This was causing a bug. It's probably
just as well, since what I was trying to do definitely fell into the
category of "clever code" rather than "clear code".
Sorry.
* Made glutSetKeyRepeat() call fgError() if you go out of range. (The
old code silently did nothing---not even a warning.)
If it is really desirable to keep running, we should probably at least
generate an fgWarning().
* Deleted some say-nothing-new comments.
* XXX added: Is glutSetKeyRepeat() deprecated?
git-svn-id: https://svn.code.sf.net/p/freeglut/code/trunk@256 7f0cb862-5218-0410-a997-914c9d46530a
* Removed some say-nothing-useful comments.
* Added some tentative mouse-wheel support.
* Fairly massive reformatting of code.
I made some secondary changes to his changes:
* One compilation error was fixed (missing close-paren + semicolon).
* Deleted a few ore say-nothing-useful comments.
* Some of John's code was strangely formatted to the point that it
seemed completely out of place, so I took the liberty of reformatting
it. Since I used GNU EMACS's <tab> key (which re-indents rather than
inserts TAB characters), I had to propogate some indentation changes
a little further than the bare necessity to match up with John's
changes. (John seems to shoot for 2-space indents, while EMACS
(and I, I confess) strongly prefer 4-space indents. The code that
I was re-indenting had been put to 8-space indents, however.)
I have *not* tested the code beyond compiling. I assume that John did
(and that the compilation error was a result a minor change just before
asking me to commit).
git-svn-id: https://svn.code.sf.net/p/freeglut/code/trunk@255 7f0cb862-5218-0410-a997-914c9d46530a
There should be no alterations to how the code performs.
(I modified how the X11 section of the set-cursor code is indented to
slightly better match (IMHO) the rest of his changes.)
git-svn-id: https://svn.code.sf.net/p/freeglut/code/trunk@254 7f0cb862-5218-0410-a997-914c9d46530a
in some cases, the Menu member variable can be NULL.)
Corrected the menu-attach code to make sure that both Window and Menu
pointers are non-NULL (rather than "at least one").
Rewrote button-checks to more simply and more clearly assert that the
"menu button" is a valid button for menu actions: Instead of laboriously
comparing against the three valid buttons (0, 1, 2 or GLUT_BUTTON_*),
we do a simpler range-check and the upper bound is {FREEGLUT_MAX_MENUS},
allowing us to change the number of menuable buttons fairly easily in
the future.
Also deleted a few say-nothing-new comments.

governed menu aesthetics. I think that it's better to have a default
that works than to break completely, should freeglut ever be ported to
a new (non-WIN32, non-UNIX/X11) target.

* Updated an old "TODO BEFORE STABLE" comment.
* Expanded a comment re. some #define macros.
* Made colors and font choice system dependant. The UNIX freeglut
menus look more like UNIX GLUT menus, now. (This is PURELY a
cosmetic change. But it achieves better compatibility visually.)

* Reformatted a say-something-useful comment to fit on an 80-column
display.

code that really needs to be system-specific is the window event handling,
which in MS-WINDOWS is tucked into a separate function. In UNIX/X11, it's
all spilled out into glutMainLoopEvent() for some reason.
If the X11 code could be tucked into another function, glutMainLoopEvent()
could be platform-independant.

glutMainLoop(), per discussion on the list. The code looks okay,
to me, though I remain less than wholly convinced that treating idles
as special cases is the best way to go. Still, a case can be made
for taking "non-event" idle callbacks out of the "event loop".
From an organizational perspective, I think that it's an improvement,
and it fixes a bug for at least one program.
git-svn-id: https://svn.code.sf.net/p/freeglut/code/trunk@244 7f0cb862-5218-0410-a997-914c9d46530a
The lines that he was altering were very oddly-split, so while I was at
it, I repaired the line-break damage.

code was not setting the GLUT window prior to calling callbacks.)
Please verify. If so, this closes out, I think, the latter half of
that bug report, so anyone with the means to modify/close bug reports
should do so upon verification of the fix.

Deleted numerous 4-line "padding" sequences of C-as-English trans-
literation comments.
Re-indented some (but not all) code that is using 2-space indentation.
(Most of the freeglut code seems to be using 4-space indentation.)
I did not touch the "INIT DISPLAY STRING PARSING" code, since it is
filled with a ton of over-long lines and also appears to be in more
flux than the rest of the code. (Well, I added one error-check
to a strdup().)

* Got rid of the "rewrite C as English" comments.
* Corrected several bogus references to "carriage returns" (in strings).
The symbols were newlines or EOLs or LFs (\n).
They were *not* carriage returns or CRs (\r).
* Clarified the comments on glBitmap() calls.

Modified the two Fractals* demos so that they only clear (for the random
one) or redraw (for the non-random one) if there is need to do so. (E.g.,
pressing the space bar should not clear and redraw the random fractal since
no parameters are altered.)

Mostly got rid of the say-it-in-English comments that were adding 1 line
of English and 2 or 3 lines of filler for each of several lines of C code.
Updated a couple of other comments, and tweaked some white-space.

(Type NONE is not properly supported, yet.)
Corrected behavior for the several old types:
* Wrong glyphs.
* Reversed glyphs (left/right confusion!)
There are some remaining imperfections, but it's a lot closer to
GLUT comformity, now.

none of them are Earth-shattering, but as I swept through
looking somewhat more systematically for errors, I picked
these off. See the diff's for details.
