Contextual (popup) menus and their options

[Eric Chatonet]

Bonjour Mark,

An Edit menu, if you want to stay compliant with all platforms  
guidelines, should always show the 'Cut, Copy, Paste' trilogy as a  
minimum.
Of course, you can disable the menu items you don't want the user to  
use but they *must* be there with their usual shortcuts :-)
So in your case, just build the menu on-the-fly at mouseDown and  
disable the Copy item according to the value of the selectedChunk:
It's always something like char 4 to 3 of field 1 (insertion point is  
placed after char 3 but there is no text selection), char 4 to 4 of  
field 1 (char 4 is selected), char 1 to 4 of field 1 (char 1 to 4 is  
selected)...

on mouseDown pButton
   local tMenu
   -----
   if pButton = 3 then
     if the selectedField = empty or target = empty then exit mouseDown
     if the short name of the selectedField = the short name of the  
target then
       -- it's the right field
       put "(Cut/X,Copy/C,(Paste/V,-,Select All/A" into tMenu
       -- easier to build the menu using commas
       replace comma with cr in tMenu
       -- cut and paste are always disabled
       if word 4 of the selectedChunk < word 2 of the selectedChunk then
         put "(" before line 2 of tMenu
         -- there is nothing to copy: copy is disabled
       end if
       put tMenu into btn "MyMenu"
       popup btn "MyMenu"
     end if
   else pass mouseDown
end mouseDown

Of course you'll set the traversalOn of the popup menu button to  
false to avoid text deselection.
