This object stores menu information to be passed to Resound from modules. Future versions will eliminate this node (I hope), when IB is able to generate menus without an application (or I learn to).
The Module Menu Node is a tree node. The root (top) node of the tree should be set with a blank Name. This node contains all the menu items to be added directly to Resound's Modules menu. Children nodes have names, and the menu items _they_ contain are for custom submenus off of the Modules Menu.
Let's say you want to make two menu options in the Modules menu. One is just a standard menu option, called "Tweak". The other displays a submenu, called "Twist", with submenu items "Bend", "Break", and "Bust". You'd generate a tree like this:
(Root Node):
Name "" (empty string)
Receiver NULL (indicates this node has submenus)
Message (not set)
Length 2 (for Tweak and Twist)
Submenu[0] points to the node Tweak
Submenu[1] points to the node Twist
Tweak:
Name "Tweak"
Receiver points to the object that will receive the Tweak message
Message selector to the message sent to Tweak's receiver
Length 0
Submenu... (not set)
Twist:
Name "Twist"
Receiver NULL (indicates this node has submenus)
Message (not set)
Length 3 (for Bend, Break, and Bust)
Submenu[0] points to the node Bend
Submenu[1] points to the node Break
Submenu[2] points to the node Bust
Bend:
Name "Bend"
Receiver points to the object that will receive the Bend message
Message selector to the message sent to Bend's receiver
Length 0
Submenu... (not set)
Break:
Name "Break"
Receiver points to the object that will receive the Break message
Message selector to the message sent to Break's receiver
Length 0
Submenu... (not set)
Bust:
Name "Bust"
Receiver points to the object that will receive the Bust message
Message selector to the message sent to Bust's receiver
Length 0
Submenu... (not set)
