Outputs: - Returns: TRUE if menu built OK FALSE (and sets error) otherwise Purpose: Base class implementation of menu builder. This function builds a menu statically by creating the appropriate objects. It does NOT call teh menu script interpreter because I am unhappy about the reliability of repeatedly calling that code. An overloaded version of this function could be written which takes in a reference to a "file" to be opened and interpreted. Note also that by building the menu programmatically it can change depending on the context within which it is opened... The standard layout for pop-up menus is: Clicked object's primary commands Transfer commands Other commands supported by the clicked object The "What's this?" command The Properties... command These are only guidelines and you can omit any sections you don't need. To implement an overriden version of this function you simply need to make it add new menu items to the root menu. There are helper functions to make this easier: BuildTransferCommands will add Cut,Copy,Paste,etc. BuildCommand will take any OPTOKEN you give it and build an item linked to that OPTOKEN.
