src/usermenu.c

   1 /* User defined menu is good, but beer's always better
   2  * if someone wanna start hacking something, He heard...
   3  * TODO
   4  *  - enhance commands. (eg, exit, hide, list all app's member
   5  *    window and etc)
   6  *  - cache menu... dunno.. if people really use this feature :P
   7  *  - Violins, senseless violins!
   8  *  that's all, right now :P
   9  *  - external! WINGs menu editor.
  10  *  TODONOT
  11  *  - allow applications to share their menu. ] think it
  12  *    looks wierd since there still are more than 1 appicon.
  13  *
  14  *  Syntax...
  15  *  (
  16  *    "Program Name",
  17  *    ("Command 1", SHORTCUT, 1),
  18  *    ("Command 2", SHORTCUT, 2, ("Allowed_instant_1", "Allowed_instant_2")),
  19  *    ("Command 3", SHORTCUT, (3,4,5), ("Allowed_instant_1")),
  20  *    (
  21  *      "Submenu",
  22  *      ("Kill Command", KILL),
  23  *      ("Hide Command", HIDE),
  24  *      ("Hide Others Command", HIDE_OTHERS),
  25  *      ("Members", MEMBERS),
  26  *      ("Exit Command", EXIT)
  27  *    )
  28  *  )
  29  *
  30  *  Tips:
  31  *  - If you don't want short cut keys to be listed
  32  *    in the right side of entries, you can just put them
  33  *    in array instead of using the string directly.
