#    Website Launch from Title
#    Version: 1.0
#    Author: modern algebra (rmrk.net)
#    Date: April 5, 2010
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#  Description:
#    This simple script adds the option to launch a website from a command on
#   the title screen. Only works in Windows, but RMVX only runs in Windows
#   anyway, so that shouldn't be a problem.
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#  Instructions:
#    Just go down to the configurable constants area at line 17 and read the
#   instructions there to see what each constant is for. Set them accordingly
#==============================================================================
# ** CONFIGURABLE CONSTANTS
#==============================================================================
MAWLT_COMMAND = "RMRK"        # The name of the new command
MAWLT_INDEX = 2               # Where the new command appears in the window
MAWLT_URL = "http://rmrk.net" # The full URL of the website to be launched
MAWLT_Y_OFFSET = -24          # Pixels Y coordinate of the window is offset by

#==============================================================================
# ** Window Command
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#  Summary of Changes:
#    new accessor variable - mawlt_index_override
#    new method - mawlt_add_command
#    aliased method - draw_item
