Very simple tab button script

[John Ridge]

Thanks to all contributors for this very helpful tutorial - I've learnt a
lot by working through the ideas, and playing with the different types of
menu button.

Could I suggest, Tom, that it might be an idea to add an opencard handler
that simply sets the menuHistory of the tab menu to (the number of this
card)? Then if the user naughtily uses some other method of going from card
to card, the tabs will still be correctly highlighted to reflect his current
location in the stack.

Personally, I prefer to keep the order of tabs independent from the
order of cards, and syncing the tab label and card names is not that
much work. Actually, keeping the card order when you get beyong a few
cards (I have 14 tabs in one project right now) is becoming more of a
burden than syncing names.

I just have an extra line in my handler so I am reminded if I haven't
added a given card yet.

 on menuPick tWhich
   if there is not a cd tWhich then beep
   go cd tWhich
 end menuPick

If you insist on using card number so you don't bother with card
names, you can still disassociate the orders if you use custom
properties of the tab button to control which card corresponds to
which tab.

 on menuPick tWhich
   go cd (the tWhich of me)
 end menuPick

or to play safer create a customProperty set

 on menuPick tWhich
   go cd (the myDestCard[tWhich] of me)
 end menuPick
