module GridMenuCommands
  #-----------------------------------------------------------------------------
  # Command Settings:
  #-----------------------------------------------------------------------------
  # This is where you can set up your new main menu buttons for your grid menus.
  # Surprisingly, this is a short little settings area. o.o
  # You can add as many main menu buttons as you want here, and all of them can
  # call a different grid menu!
  #
  # Format:
  #
  #   "Command Name" => {
  #     :index => number, :module => Module_Name,
  #     :enable => enable_setting, :show => show_setting,
  #   },
  #
  # Details:
  #
  #   "Command Name" => { *settings inside* },
  # The "Command Name" will be the text displayed for your command button in the
  # main menu. Make sure that there are no duplicates in the settings!
  #
  #   :index => number,
  # This determines where exactly the button will appear on the main command
  # list. 0 means the 1st command, 1 means the 2nd command, and so on.
  #
  #   :enable => enable_setting,
  # This uses the same format and options like the :enable setting in the
  # Image Grid Menu script. You got the same options, so you can set it to:
  # 1. An integer number. That number will be the ID of the switch will have to
  #    be turned ON in order for the command to be enabled.
  # 2. A symbol. The symbol will be the name of the method called. The result
  #    of the method will decide if the command is enabled or not.
  # 3. A string. The string will be a valid ruby code which will be evaluated.
  #    the result will decide if the command is enabled or not.
  # 4. An array. The array's first element will be the name of the method called
  #    and the second element will be another array containing the method's
  #    arguments. The arguments are evaluated in this module, so they will all
  #    be static arguments! The result of the method will decide if the command
  #    will be enabled or not.
  # 5. A boolean value. This means either true or false. If you set it to true,
  #    the command will always be enabled, and if you set it to false, it will
  #    always be disabled. Not much point in the latter, but it's there. :P
  # The methods and codes in option 2, 3 and 4 will be evaluated in the
  # Window_MenuCommand class!
  #
  #   :show => show_setting,
  # This is the same as the above :enable setting, but this will decide if the
  # command will show up on the list or not.
  # Got the same layout and options as the :enable setting.
  #
  #   :module => Module_Name,
  # This is the name of the module which contains your image grid menu settings.
  # This will decide which grid menu will be called, which means that you can
  # add a main menu button for all of your grid menus if you want.
  # Only use valid module names which contain grid menu settings!
  # The default grid menu uses the module named SGridMenu.
  #-----------------------------------------------------------------------------
  MainCmds = {
    "Stage Selection" => {
      :index => 5, :enable => true, :show => true, :module => SGridMenu,
    },
    # Add more main menu command settings here for your grid menus!
  }
