So lets stay that I have a control called "Foo" and I am using a datagrid
named "PeopleList"
I normally would do the following to set up the scroller:
iphoneControlCreate "scroller"
put the result into sScrollerId
iphoneControlSet sScrollerId, "rect", the rect of group "PeopleList"
put the rect of group "PeopleList" into temp
put the dgFormattedHeight of group "PeopleList" into item 4 of temp
iphoneControlSet sScrollerId, "contentRect", temp
on scrollerDidScroll pOffsetX, pOffsetY
lock screen; set the dgVScroll of group "PeopleList" to pOffsetY; unlock
screen
end scrollerDidScroll
Your saying that I should include both "Foo" and "PeopleList" together inside
of an encompassing group, let's call it "Boo"
Still use the rect of the group "PeopleList" for the scroller rect but set the
content rect to
(the dgFormattedHeight of group "PeopleList" + the height of group "foo".
Are you suggesting that it is necessary to switch between scrolling
"PeopleList" and "Boo' with a single scroller?
on scrollerDidScroll pOffsetX, pOffsetY
lock screen;
if pOffset > the height of group "Foo" then
set the vScroll of group "Boo" to the height of group "Foo"
set the dgVScroll of group "PeopleList" to pOffsetY - the height of
group "Foo";
else
set the dgVScroll of group "PeopleList" to 0
set the vScroll of group "Boo" to pOffset
unlock screen
end scrollerDidScroll
Am I understanding this correctly?
