Hi I hope someone can help me with the following problem: I have attached a menu class which is part of a project I have written. As my main menu names can be multiple lines I am using the image facility, without text, of Menu. However I cannot get an accelerate key to work. Can anyone please assist me? --

Use this to class to draw menus as follows:
Create a list of lists of MenuBar Items for example:
men = [["MM","Control", "Control Routines and exit"],
["MM","General", "General Ledger Menu"],
["MM","Creditors", "Creditor's Ledger Menu"],
["MM","Debtors", "Debtor's Ledger Menu"],
["MM","Stores", "Stores Ledger Menu"],
["MM","Help", "User's Manual and About","right"]]
Where the fields are as follows:
MM = Main Menu:
Menu Name
Detail
CM = Cascade Menu:
Parent Name
Menu Name
Detail
Create a list of lists of Menu Items for example:
mod = [["F","Control","tarCfg","Configure Tartan"],
["PNN","Control","co1010","Company Records"],
["F","Control","sysEnd","Exit Program"],
["CY","Control","l -l","Directory"]]
Where the fields are as follows:
Type F = Function
P123 where 1 = Requiring Company Number (Y/N)
2 = Requiring Period Selection (Y/N)
3 = Pass the User Name to the Module
Parent Menu Name
Program, Function or Command
Security Level
Prompt
Routine number if required for type P above
Draw the menus as follows:
menu = TartanMenu(usr, men, mod, ign, lvl, cmd)
mf = Tartan MainFrame
usr = User Name
men = Menues
mod = Modules
lvl = Security Level
cmd = Command to Execute on Selection
img = Background Image to Display
