Add to a field sprite to emulate the standard lingo menu functions. Useful for SW or for creating menus with your own font styles

-- add to a field sprite to emulate the menu function in SW -- Shortcuts work with shift rather than ctrl (an unfortunate necessity) -- NB - this behaviour uses the mousedownscript and keydownscript, -- and needs to be adapted if these are needed elsewhere in the movie -- Danny Kodicek 1999 (please credit) --Any comments / problems / improvements to danny@toifund.com property pmenu -- the menu member property pmouseselection -- the currently selected line property pmenuitems -- list of lists of menu items for each menu property popening -- is there a menu currently popped property pmenudownsprite -- the sprite holding the menu popup (needs to contain a dot) property pmenumember -- the member of the popup (created dynamically) property ptoptext -- the menu bar text property pfont, psize -- style of the text on getpropertydescriptionlist me   lyst=[:]   addprop lyst, #pmenu, [#comment: "Member of menu text", #format: #field, #default:""]   addprop lyst, #pmenudownsprite, [#comment: "Menu down sprite", #format: #integer, #default: 100]   addprop lyst, #pfont, [#comment: "Font", #format: #string, #default: "Times"]   addprop lyst, #psize, [#comment: "Font size", #format: #integer, #default: 12, #range: [#min: 8, #max: 18]]      return lyst end on getbehaviordescription me   t="Emulates the installmenu command; choose your own fonts"   put "and sizes or use it in Shockwave" after t   return t end on getbehaviortooltip me   t="Add to a field sprite, specifying a second sprite for the"&return   put "drop-down menu and a field cast member containing a standard"&return after t   put "lingo menu (only supports enable, disable, lingo handler,"&return after t   put "shortcut and blank line functions.
