   1 This package contains Common Lisp bindings to GTK+ v2.x. It currently
   2 works with CMUCL 19, SBCL 0.9 and CLISP. Ports to other CL
   3 implementations may be added later.

  14 Build instructions
  15 ------------------
  16
  17 1. If you are using a version of SBCL without native callback support
  18    you need to upgrade or add third party callback code. The following
  19    instructions of how to add callback support, are borrowed
  20    from the Common Music installation guide:
  21
  22    1. Download Thomas Burdick's Alien Function package¹ and restore it
  23       to a directory on your machine.
  24    2. Compile the Alien Function package and save a new sbcl.core image:
  25
  26       $ cd sbcl-af
  27       $ sbcl --load "system"
  28       * (sb-ext:save-lisp-and-die "/tmp/sbcl.core")
  29       $ cd /usr/local/lib/sbcl
  30       $ cp sbcl.core sbcl.core.orig
  31       $ mv /tmp/sbcl.core .
  32
  33
  34    ¹ A slightly modified version which works with SBCL 0.8.21 or newer
  35      could be found at
  36      http://jupiter.td.org.uit.no/lisp/sbcl-0.8.21-af.tar.gz
  37
  38
  39 2. Set up paths to match your system:
  40
  41    - Add a logical-pathname-translation to the clg root directory in
  42      ~/.cmucl-init.lisp, ~/.sbclrc or some other startup file, like
  43      this:
  44
  45        (setf
  46          (logical-pathname-translations "clg")
  47          '(("**;*.*.*" "/home/espen/src/clg/**/")))
  48
  49    - Set the correct pkg-config search path if your Gtk+ installation
  50      is in an unusual place, by adding it to the PKG_CONFIG_PATH
  51      environment variable before starting lisp.
  52
  53    - Make sure ASDF finds the system definition files:
  54
  55        (push
  56         (translate-logical-pathname "clg:systems;")
  57          asdf:*central-registry*)
  58
  59
  60      When checking out of CVS also do the following:
  61      $ cd <clg toplevel>
  62      $ mkdir systems && cd systems
  63      $ find .. -name '*.asd' -exec ln -s {} . \;
  64
  65
  66 3. Compile and load the system:
  67
  68      (asdf:oos 'asdf:load-op :gtk)
  69
  70    In CMUCL 19a this will fail with:
  71
  72    Error in function KERNEL::%REDEFINE-DEFSTRUCT:
  73      Redefining class PCL::SLOT-INFO incompatibly with the current definition.
  74
  75    Just accept the redefinition (restart 1) to continue building or
  76    loading. To avoid doing this every time clg is loaded, compile
  77    and load glib/pcl.lisp in newly started CMUCL process and save a
  78    new core image.
  79
  80    If you are running SBCL with Slime you need to put the following
  81    in ~/.swank.lisp to prevent Slime from spawning multiple
  82    threads, since GTK+ is not really thread safe:
  83
  84      #+sbcl(setq swank:*communication-style* :fd-handler)
  85
  86    CLISP needs to be started with the option '-ansi' for clg to
  87    compile and load.
  88
  89
  90 4. If everything worked, try (load "hello-world") to see a small
  91    window pop up, and then run testgtk.lisp in the example directory.

  95 Guidelines for using the GTK+ API documentation
  96 -----------------------------------------------
  97
  98 Here are some brief guidelines for using the GTK+ API documentation. A
  99 lot of (both intentional and unintentional) inconsistencies exists,
 100 so it is also wise to check the source code.
 101
 102 - library prefixes are stripped from all symbols
 103
 104 - object properties should be available as virtual slots. A lot of
 105   "missing" properties are manually defined as slots. Slots may be read
 106   only or write only, but there later type are generally only
 107   defined automatically through introspection
 108
 109 - the get/set part are removed from regular accessors, but retained
 110   in functions which set or retrieve multiple values
 111
 112 - predicate functions follow the normal convention of ending
 113   with '-P'
 114
 115 - if there are multiple similar named functions which only differ in
 116   the type of argument they accept, only one function accepting any
 117   kind of valid argument types is provided
 118
 119 - there are no gtk_*_new functions, use MAKE-INSTANCE to create widgets
 120
 121 - use CHILD-PROPERTY-VALUE or automatically defined accessors to
 122   access child properties
 123
 124 - use STYLE-PROPERTY-VALUE to access style properties
 125
 126 - the only function used to connect signals is SIGNAL-CONNECT
 127
 128 - some additional initargs to make-instance:
 129
 130   - gtk:container
 131
 132     child -- adds a child to a container widget. This argument could
 133     be a widget or a list who's first element is a widget and the rest
 134     child properties. Multiple :child initargs may be specified
 135
 136     children -- list of children to be added
 137
 138     child-args -- default child properties used when adding children (during
 139     construction only)
 140
 141     show-children -- automatically make children (and grandchildren)
 142     visible. May be overridden in a child by explicit specifying :visible or
 143     another :show-children
 144
 145
 146   - gtk:button
 147
 148     stock -- equivalent to ":label stock :use-stock t :use-underline t"
 149
 150
 151   - gtk:dialog
 152
 153     button -- button specification applied to dialog-add-button. Multiple
 154     :button initargs may be specified
 155
 156     buttons -- list of button specifications
