[Lisp-cffi-qt4-list] Hiding the console window

[Radoslav A. <rsd...@gm...>]

Hi, again!

I saved a CLISP image with ASDF, CFFI, and some more packages in it... 
Then I associated *.lisp files with this image and now I have small 
"script" interpreter (so I can write small single-file programs without 
all the burden of loading often used packages... (isn't Lisp cool ?!)

(Some weeks ago I tried to save an image with "qt.lisp" loaded. I saved 
it successfully, but at runtime it broke miserably... So I still need to 
load "qt.lisp" in the code)

The real issue I wanted to concern is this annoying console window. 
CLISP is console application, and also are the executable (:executable 
t) images it saves. So doble-clicking on a *.lisp file my image first 
shows a console window and then the QT application window, over it. 
(I've read somewhere that the ECL guys had already addressed that issue 
and the Windows version is able to build "windows" subsystem standalone 
applications, for which the win32 loader doesn't create a console). As 
still there is not (at least I couldn't find) a corresponding CLISP 
solution - I approached it in a FFI way, first trying CFFI, which turned 
out does not support the STDCALL calling convention :(( So I fell 
through to CLISP's FFI:

Fortunately this works - the console window disappears shortly after the 
program is run and only the main window remains, working :)))
Unfortunately only till the main window is closed - then I get a "Don't 
send" error message...

Any ideas?

Re: [Lisp-cffi-qt4-list] Unicode (2)

[Radoslav A. <rsd...@gm...>]

Hi, Paul.
At first, thank you for the quick response.

Unfortunately I still cannot pass UTF-8 encoded string from CLISP. I 
think the problem is either in the way CFFI is used or in CFFI 
(implementation for CLISP) itself.
Later I found a statement <http://www.cliki.net/Unicode%20support> 
saying that "CLISP: FFI can pass strings only with single-byte encoding" 
and this explains the error message I got: "1087 cannot be converted to 
the foreign type FFI:UCHAR".

I think this statement is a outdated, but still looking at 
http://clisp.cons.org/impnotes.html#dffi-types it seems that CLISP's 
ffi:uchar is 8 bit. I also tried
 (setf custom:*foreign-encoding* charset:utf-8)
but the error persisted.

And finally one more thing: (the latest version of) CFFI don't work 
properly with the latest version of CLISP (2.41). It's quite normal of 
course, at it is still new and probably they changed their FFI in some 
way. But my idea is: is it possible at all to pass a UTF-8 string with 
CLISP FFI, and if, how to make it work with CFFI? I'll continue trying, 
but if you have some ideas please share ;)

I'm also not a Unicode expert :)) But while UTF8 is to some extent 8bit 
transparent, yet it is not a full righted 8bit string. For example 8bit 
functions for string length won't give correct result, as they count 
each byte as a character, which is not the case in UTF-8 (some 
characters are encoded with much more bytes...).

No problem ;))The good thing with me is I'm not in a hurry. I really 
have too much to do, so I hardly find time for Lisp. But still I dream 
for the day I'll have the tools and the time to write production, 
crossplatform Lisp/Qt (/Unicode) code :)) For now I would be content 
with the little I can contribute...

[Lisp-cffi-qt4-list] Unicode

[Radoslav A. <rsd...@gm...>]

Hi, Paul :)

What about Unicode support in lisp-cffi-q4?
You see, I'm a Bulgarian student in Germany, and currently I'm learning 
greek :-D Even for simple notes I need some Unicode support...

AFAIK Qt4 has a mature Unicode support. There are CL implementations 
with good Unicode support. So what could break the flow is either CFFI 
or lisp-cffi-qt4. I spent a little time trying to understand what about 
CFFI, but I couldn't, so I decided just to try.

What I tried is the following:
As I work on Windows, I had to choose CLisp as an implementation, as ECL 
is still not quite Unicode compliant. I had to use 2.38, because the 
last one (2.41) had some problems loading "qt.lisp", probably with CFFI 
... (On 2.38 lisp-cffi-qt4 works just fine, at least the simple tests.)

I tried this (having UTF-8 encoded file utf.txt, containing Bulgarian, 
German and Greek words on its first line):
> (load "asdf")
> (load "qt")
>
> (defpackage qt-user (:use cl qt))
> (in-package qt-user)
>
> (defvar *unicode-string* nil)
> (let ((custom:*default-file-encoding* charset:utf-8))
>     (with-open-file (f "utf.txt")
>         (setf *unicode-string* (read-line f))))
>         
> (with-qt ()
>     (object lb `(label ,*unicode-string*)))
(All CLisp guru's, excuse my ignorance of a better way to write the code 
above...)

And got:
> ...

Of what I see, I can suppose that (at least CLisp's mplementation of) 
CFFI doesn't support Unicode. Am I right, or the way lisp-cffi-qt4 uses 
CFFI is not Unicode compliant?

Hi, Paul.

Thank you so much for the quick and relevant response :)
I'm looking forward the new version, to continue my toy-thing, and give 
you more feedback ;)

Re: [Lisp-cffi-qt4-list] text-browser's anchor-clicked signal

[Radoslav A. <rsd...@gm...>]

If I remove the "connect" form it works just fine. If I connect another 
signal (e.g. text-changed), it also works. I also tried with "text-edit" 
instead of "text-browser" - the effect was the same. For me that's a 
hint, that the problem is in "anchor-clicked" signal's implementation.

[Lisp-cffi-qt4-list] text-browser's anchor-clicked signal

[Radoslav A. <rsd...@gm...>]

Hi, all.

At first, thanks to the author of the project - it's something I was 
waiting to find :)

I'm just playing with 0.2g, and it worked fine with some simple things I 
tried. The first toy I have in mind is to build a simple browser for 
some preformatted text, so I tried the following:

I tried with (lamda () ...), #'(lambda () ...), (lambda (&rest) ...), 
#'(lambda (&rest) ...) and then with defun-ed function... - getting each

Any ideas?

P.S. I see that the mailing list is not used much, but I had no other

I'm also a SF project administrator, of a small, almost dead, C++/QT

Re: [Lisp-cffi-qt4-list] Newest release on Mac OS X

[Benjamin N. <be...@NB...>]

Just letting you know that some of the problems I've been observing on 
Mac OS X seems to have been resolved (i.e. the problem with the widgets 
behind behind the emacs window, and being able to input text into text 
edit widgets)

When I run the examples, I now get a separate "sbcl" icon in the dock, 
and the event looping looks OK :)

Re: [Lisp-cffi-qt4-list] Greetings

[Benjamin N. <be...@NB...>]

Ok the examples work now if I do >(load "1-hello-world.lisp") from 
within Emacs+Slime. Not sure what was wrong, but I think what was 
happening is that the "Hello World" window actually appeared underneath 
my emacs window and I couldn't see it.

The problems with the scroll bars and not being able to input text into 
a line-edit is still there though. Also, the Qt widgets are always begin 
the Emacs window. I think this is a Mac OS X issue, so I'll still try 
thing out on Linux+X11 and let you know how it goes.

Cheers
Benjamin

Hi

Thanks for the reply :) I'll definitely try out Emacs+Slime on a linux 
machine. Just a question, should the examples all be fully functional? 
in the widget example ("7-widget-examples"), input to line edit don't 
work, and the scroll bars don't work either. I'm wondering if this is a 
Mac OS X issue.

But like I said, I'll try thing out on a Linux box and see what the 
results are...

Good luck with your life changes :)

Ciao
Benjamin

Hi

An update on my previous post. I've gotten things working by doing it 
from the command line instead of Emacs+Slime. The examples work now :)

Any ideas on how to get thing working from within Emacs+Slime?

Platform: Mac OS X 10.4
LISP: SBCL

Regards
Benjamin

Hello Lisp-cffi-qt4

I'm new to LISP, but have lots of Qt experience, and potentially want to 
use LISP+QT4 in our project. The aim is visualisation of bioinformatics 
data. So, I'd like to get involved and contribute to the project. I've 
downloaded the code, but haven't got things working yet.

As I said, I'm new to lisp, but I've tried getting thins working by doing
1. Changing loading the foreign lib to (load-foreign-library #+unix 
"./libgui.dylib" #+win32 "gui")
2. (compile-file "qt.lisp") (I had to do a manual (asdf:operate 
'asdf:load-op :cffi) to get it to work)
3. (load "qt.fasl")
4. (compile-file "1-hello-world.lisp") (I commented out (run) first)
5. (load "1-hello-world.fasl")
6. (run)

And I get:
HELLO-WORLD> (run)
NIL

Should I be seeing a hello world?
The other examples exhibit the same behaviour

Any ideas?

Platform: Max OS X 10.4
LISP: SBCL

Regards
Benjamin
