Re: Setting mobile scroller hScroll fails
Whenever someone says "math" my eyes kind of glaze over and my brain
shuts off. I'm using your sample script to resize the group so it
expands to the screen edges, which works great. I'm not sure how to
change the scroller so it works with that setup, but I did wonder if
scrollers were limited to the card size and that might be why it wasn't
working.
I think I'll write it up as Monte suggested, though I'm not sure whether
to call it a bug, a feature request, or just impossible.

had to set the hScroll before. It's always been zero.
In this case, I set the hScroll of the group to the formattedWidth of
the group, which may be wrong. The engine seems to compensate though and
sets the scroll as far as it should go. Then I call "createScroller" and
pass the name of the group. The handler:
command createScroller pName
-- pName = the long ID of a grp
put the rect of control pName into tRect
put the hScrollBar of control pName into tHScroller
put the vScrollBar of control pName into tVScroller
put the hScroll of control pName into tHScroll
put the vScroll of control pName into tVScroll
set the hScrollBar of control pName to false -- remove fld scrollbars
on mobile
set the vScrollBar of control pName to false
mobileControlCreate "scroller", pName
mobileControlSet pName, "rect", tRect
put ("0,0," & (the formattedwidth of control pName) & "," & the
formattedheight of control pName) into tContentRect
mobileControlSet pName, "contentRect", tContentRect
mobileControlSet pName, "hScroll", 0
mobileControlSet pName, "vScroll", 0
mobileControlSet pName, "hIndicator", tHScroller
mobileControlSet pName, "vIndicator", tVScroller
mobileControlSet pName, "hScroll", tHScroll
mobileControlSet pName, "vScroll", tVScroll
mobileControlSet pName, "visible", true
end createScroller
I initialize both the group and the scroller to 0 before doing anything
else, because when I wrote it I couldn't get them to align correctly
otherwise. I should also probably mention that I'm using fullscreenMode
"showAll" and the group is expanded beyond the borders of the card to
fill the screen; i.e., it probably has a negative left margin and a
wider right margin. When the scroller finally does scroll (after
resetting itself) it scrolls too far at the left side by the number of
pixels between the screen left and the card left, and cuts off the same
amount on the right side.
Can you see what I should change?

zoom the group out to fill the screen
create a mobile scroller with the same rect
set the hScroll of the group to its formattedWidth
set the hScroll of the scroller to the scroll of the group
If I insert an answer command to show the scroller's hScroll it reports the
correct number. But the scroller always acts like its scroll is 0, and it won't
scroll to the left at all. But scrolling it to the right zaps both it and the
group to zero and after that it scrolls normally.
I've also tried not setting the group's scroll and just setting the scroller
alone, thinking it might trigger the scrollerDidScroll handler, but it doesn't.
If I don't set any hScroll at all on either the group or the scroller, all is
well.
Has anyone else seen this?

The max scroll will be the formattedWidth of the group - the width of the group
unless you have unboundedHScroll true. I _think_ if it’s false then the engine
will automagically clamp that though.

I’m really not sure at this stage. Have you tried logging the x,y values you
get in scrollerDidScroll? This may need a simple stack to reproduce it and an
email to support so we can figure out what’s up.

Re: Setting mobile scroller hScroll fails
I think it is going to take some math but the scroller should be set for the
area within the card rect since the areas left/right are not going to be
responsive to the scroller.

Re: Setting mobile scroller hScroll fails
Thanks Monte, I did over-summarize. I'm not sure why it's going wrong,
but it sounds like it's something I'm doing. I have a standard
"createScroller" handler that I've been using for years, but I've never
had to set the hScroll before. It's always been zero.

the group, which may be wrong. The engine seems to compensate though and
sets the scroll as far as it should go. Then I call "createScroller" and
pass the name of the group. The handler:
command createScroller pName
-- pName = the long ID of a grp
put the rect of control pName into tRect
put the hScrollBar of control pName into tHScroller
put the vScrollBar of control pName into tVScroller
put the hScroll of control pName into tHScroll
put the vScroll of control pName into tVScroll
set the hScrollBar of control pName to false -- remove fld scrollbars
on mobile
set the vScrollBar of control pName to false
mobileControlCreate "scroller", pName
mobileControlSet pName, "rect", tRect
put ("0,0," & (the formattedwidth of control pName) & "," & the
formattedheight of control pName) into tContentRect
mobileControlSet pName, "contentRect", tContentRect
mobileControlSet pName, "hScroll", 0
mobileControlSet pName, "vScroll", 0
mobileControlSet pName, "hIndicator", tHScroller
mobileControlSet pName, "vIndicator", tVScroller
mobileControlSet pName, "hScroll", tHScroll
mobileControlSet pName, "vScroll", tVScroll
mobileControlSet pName, "visible", true
end createScroller
