Graphic-Forms 0.9.0

Copyright (c) 2006-2007, Jack D. Unrue

Graphic-Forms is a user interface library implemented in Common Lisp focusing on the Windows(R) platform. Graphic-Forms is licensed under the terms of the BSD License.

This is a fork of original Graphic-Forms in common-lisp.net by Mr. Jack D. Unrue. Thanks to his great work, Graphic-Forms is a comprehensive Windows GUI toolkit, with through tests, useful docs and demos. Unfortunately, it’s not maintained for a while and can’t live well with new version of its Lisp Dependencies. This fork does some fixes to make Graphic-Forms work under new verison of Windows and can be loaded through QuickLisp. A small amount of bug fix is also done but new functional improvement will be made in future version. All demos, unit tests and examples work correctly now, Graphic-Forms is now good for Windows GUI programming again.

Quickstart

Download or clone the project and put it tnto QuickLisp’s local project directory and evaluate: (ql:quickload :graphic-forms). You can then view demos by:

;; a simple text editor
(gft:textedit)

;; a block elimnating game
(gft:unblocked)

To make further configuration about plugins, see the Detailed Instructions on Installation section. To view other examples please see src/tests/uitoolkit/README.txt for details.

Screenshots

Here are the screenshots for the two demos on Windows 7:

  • TextEdit:

./etc/textedit.png

  • UnBlocked:

./etc/unblocked.png

Detailed Instructions on Installation

  1. [OPTIONAL] Install ImageMagick 6.2.6.5-Q16 (note in particular that it is the Q16 version that is needed, not the Q8 version). The default installation directory is “c:/Program Files/ImageMagick-6.2.6-Q16/”.
  2. Download or clone the project and put Graphic-Forms to a QuickLisp local project directory (Hopefully it will be add to QuickLisp’s Package Index next month.
  3. Execute the following forms at your REPL:
(ql:quickload :graphic-forms)
  1. If you want more image type support with ImageMagick, Execute the following forms at your REPL

(push :load-imagemagick-plugin *features*) 

(setf cl-user::*magick-library-directory* "c:/path/to/ImageMagick/")

  1. Execute the following forms at your REPL:
(ql:quickload :graphic-forms)~
  1. Proceed to the next section to run the tests, or start coding!

How To Run Tests And Demos

  1. Load the graphic-forms system as described in the previous section
  2. Execute the following forms from your REPL:
;; execute demos and test programs 

(gft:hello-world)
(gft:unblocked)
(gft:textedit)

;; see src/tests/uitoolkit/README.txt for details on other test programs

;; execute the unit-tests 
(in-package :gft) 
(run-tests)

Dependencies

Graphic-Forms requires the following libraries. When load Graphic-Forms, all of them can be loaded automatically via QuickLisp.

To run tests, you need:

The following libraries are optional:

Supported Common Lisp Implementations

Graphic-Forms currently supports SBCL 1.3.9, CCL 1.11 on Windows 7 x86. Older version of SBCL, CCL, CLisp with x64 version of Windows 7 and other Windows versions should also work, but not tested yet. Tests on other implementations and different version of Windows are welcomed. Original Graphic-Forms has Allegro CL and Lispworks support, but I am not able to test on commercial platforms.

Known Problems

Aside from the fact that there are a myriad of classes, functions, and features in general that are not yet implemented, this section lists known problems in this release:

  1. The following bug filed against CLISP 2.38

    http://sourceforge.net/tracker/index.php?func=detail&aid=1463994&group_id=1355&atid=101355

    may result in a GPF if a window’s layout manager is changed. Compared to prior releases of Graphic-Forms, there is much less chance of this problem affecting layout management.

  2. Please be advised that SBCL is itself still in the early stages of supporting Windows, and as a consequence, you may experience problems such as ‘GC invariant lost’ errors that result in a crash to LDB.
  3. The ‘unblocked’ and ‘textedit’ demo programs are not yet complete.
  4. The gfg:text-extent method currently does not return the correct text height value. As a workaround, get the text metrics for the font and compute height from that. The gfg:text-extent function does return the correct width.
  5. If a Graphic-Forms application is launched from within SLIME with CLISP or SBCL as the backend (both of which are single-threaded on Win32), further SLIME commands will be ‘pipelined’ until the Graphic-Forms main message loop exits. If/when these implementations gain multi-threading support on Win32, then the Graphic-Forms library code will be updated to launch a separate thread, as is currently done for Allegro and LispWorks.
