Hi,
I use tabbed buttons in my user interface. They work easily enough,
but every reference to how this is done uses the "on menuPick
pNew,pOld" handler. And every reference seems to use a switch or
something to recognise the tab that was clicked based on the
*visible* text. Sometimes a cardname = tabname trick is used.
This means that the visible text on the tab is used in two places and
the RR user has to remember to change these values so that they match.
This is generally a Bad Thing, just out of principle. It means that
when the text of a tab is changed the script has to be changed. This
is a Really Bad Thing when trying to localise the application: each
tab will have multiple text values, where, as you'd know if you've
ever been involved in such a thing, the localised text is pretty much
guaranteed to change a number of times. (And the cardname = tabname
obviously won't work in this situation).
Way too error prone.
So, it turns out that there is a property that lists the tab labels,
so I can write something along the lines of:
on menuPick pNew,pOld
get the properties of me
put it["text"] into labels
put 1 into tabNumber
repeat for each line aLabel in labels
if pNew = aLabel then exit repeat
add 1 to tabNumber
end repeat
switch tabNumber
case 1
go card "card_one"
break
case 2
go card "card_two"
break
case 3
go card "card_three"
break
default
go card "card_one"
break
end switch
end menuPick
I checked this and it does localise correctly.
Any better ways of doing this?
There is nothing particularly clever about what I'm doing, but I'm
new to RR and this kind of thing is a) not obvious to a new user (how
to find the name of a property is not obvious to me at least); and,
b) a nasty trap if not addressed by the RR programmer. The event
"menuPick" isn't something I find particularly obvious either.
It would be good if this was either fixed in RR or that this, or some
better technique/trick, was more widely documented.
Cheers,
Bob
