GUI library/toolkit recommendation

Hi,

I want to write a very simple app in CL that does the following:

- creates a fullscreen window with a white background,

- left clicks paint the whole window with a color that is calculated
from the (x,y) coordinates

- right clicks exit.

It should work on X11, but other platforms would be nice too. I am
looking for recommendations on what library to use for this -- I don't
know much about GUI programming in CL.

In case anyone is wondering: I want to use this for LCD testing.

Best,

Tamas

Check out Ltk: http://www.peter-herth.de/ltk/
Should be available anywhere you can install Tcl/Tk, and is probably
the most straightforward Gui to get started with in Common Lisp.

That didn't stop you from producing several substandard GUI libraries
for CL, IIRC CL-cairo and cl-2d , a few years ago?

Whoah! Impoliteness seems fine on this newsgroup but flat-out
unpleasantness isn't necessary.

Note that cl-2d is for plotting, using Cairo (via cl-cairo). Neither of
these is concerned with questions like "Where is the mouse?" or "Has
someone clicked recently?" or ...

This sounds like you'd probably like a lighter-weight solution than all
of CLG, but if you're interested there's a not-quite-so-broken version
at my Github repository (https://github.com/rswarbrick/clg). It
definitely compiles and loads with SBCL; I haven't tested other
implementations. Playing a slo-mo game of whack-a-mole to try and fix
assumptions that the original author made that aren't true in 2012
(either because of changes in SBCL or in Gtk).

I suggest you use the kill file faciliuty instead to avoid seeing any
messages from me, and that would help avoid both of us wasting any more
time on each other --- Madhu

Thanks! LTK is fantastic. Here is the script that I wrote as a solution:

http://paste.lisp.org/display/129192#1

Maybe I'll make it standalone, there is no comparable utility that I
could find for Linux.

Best,

Indeed :-)

CLG definitely looks interesting, but I ended up solving the problem
with LTK. Now I have my dead pixel tester utility - in CL!

I noticed that the library has some Cairo bindings. If you happen to
find maintaining that part burdensome, you might want to take a look
at cl-cairo2 -- it definitely underwent a period of neglect (I wasn't
using it), but Ryan Pavlik has taken over recently and he has been
very active.

Best,

Cool!

Indeed! I've actually used them myself with some (very incomplete)
poppler bindings. CLG is a reasonably old project and I'm quite new to
it. There's a huge amount of cruft to do with supporting different
implementations, seemingly reimplementing CFFI, BORDEAUX-THREADS,
CLOSER-MOP etc. etc. [1]

As such, my grand plan is to gently take an axe to the codebase,
replacing such brittle stuff with calls to portability wrappers. And
also make the library a bit more rock solid. And maybe even add some
docstrings... And, of course, move to Gtk3.

The plan is to end up with a smaller library with the same functionality
and one that I (or someone else) could plausibly keep in shape.

If I can find a way to replace the Cairo bindings with calls to
cl-cairo2, I'll definitely do so. That's probably some way down the list
though, since I'm not using much of Cairo for the application I'm trying
to write with it at the moment.

[1] To be fair, I haven't checked: these might not have existed when
some of CLG was written.

I do make some money off Quicklisp. I accept donations, and people have
donated. I've use that money to go to Lisp meetings, buy computer
hardware, and buy a beer or lunch occasionally.

Oh, and to pay for hosting, too, though the price for hosting is pretty
low. Amazon has a pretty great deal going for my Quicklisp needs.

It would have done those greeks well to look up the Trojan horse at the

You should stop being naive, or you should stop working for satan.

The library market isnt an honest about software, it is about bandwidth
advertising and about getting 3rd-party-controlled-infrastructure on the
customers machine on the google "people" model.

It would appear that the only people left here are the marketing types
whose value for the NWO comes from their loudness in shaping uninformed
opinion on this newsgroup. and marketing. So far we have an endorsment
for Amazon.

Hi Zach,

My original statement left room for misinterpretation.

By my understanding, you are accepting donations for a serious hobby
project and are not making any "real money" that you can rely on.

I wouldn't mind if you are making a small profit. You might want to
make an announcement if you do start pulling in substantial donations
(comparable to pay for the time and resources you put in each month).
Transparency helps people have fair expectations. Showing that the
community supports core projects is a success story for CL in its own way.

Actually, the Greeks were inside the horse. A common misconception.

Only 5 years. Come on! It has taken him longer for shorter programs
