See other post… the dictionary says
Optional string to use to identify the control. The controlName must be unique
amongst all existing controls and cannot be an integer.
so I set the name of the group of links on
Stack A home.livecode | card 1 | group "portal-links"
on open card
createScroller "portal-links"
Stack B surprise-me.livecode t| card 2 | group "surprise-links"
on open card
createScroller "surprise-links"
things improved somewhat…
It does not matter whether I use this or Ralph's code (I did set the
scrollingEnabled)
And it does not matter whether if we put this in the back script or duplicate
it in each stack script (not ideal.. but just to test…)
go stack 1 # from button on Stack 0 -- scroller on stack 1 scrolls
go stack 2 # from button on stack 1 -- scroller on stack 2 scrolls
go stack 1 # from button on stack 2 -- scroller on stack 1 no longer scrolls
go stack 2 # from button on stack 1 - scroller continues to scroll now on stack
2
ergo the scroller on Card 1 | Stack A "group "portal-links" has been deleted.
theoretically on desktop, one would trap "resume stack" in the stack being
re-activated. but "resume stack" is not amessage that fires on mobile… so when
switching between stacks on mobile that are, presumably, still open in memory,
how to fire a script in the stack being re-activated? (assuming this is the
solution… to the scrolling problem we would delete and re-create the scroller
on the fly, though this seems overkill…I don't see anything in the dictionary
that says we cannot have multiple mobile scrollers open and funcational at the
same time… though perhaps this is mandated but no documented?
command CreateScroller pName -- scrolling regions,groups, fields
if not isMobile() then exit CreateScroller
deleteMobileControl pName -- delete any existing
# it also doesn't help to comment out the above line…
put (the rect of control pName) into tRect
mobileControlCreate "scroller", pName
mobileControlSet pName, "rect", tRect
put ("0,0," & (the formattedwidth of control pName) & "," & the formattedheight
of control pName) into tRect
mobileControlSet pName, "contentRect" , tRect
mobileControlSet pName, "hScroll" , 0
mobileControlSet pName, "vScroll" , 0
mobileControlSet pName, "hIndicator" , false
mobileControlSet sName , "scrollingEnabled" , true
mobileControlSet pName, "visible", true
end CreateScroller
on scrollerDidScroll hScrolled, vScrolled
put mobileControlTarget() into tControlID
set the vscroll of control tControlID to vscrolled
pass scrollerDidScroll
end scrollerDidScroll
