Well folks,
I finished converting most of my indicator system over to these new
hierarchical and conditional params today. Then I ran into a
situation that I had not run into before. With all my param sections
open, The parameters window has the scroll bar enabled, and it takes
about 3 windows full of parameters to show them all. That would be
fine if it were not for the fact that every param that changes the
layout in some way calls for the Reset all button to be clicked by
AutoIt. When this happens, it also resets the scroll bar back to the
top. This is of no consequence most of the time for me, because I
rarely have enough params open at the same time to require the scroll
bar. However, it is confusing when I click on a param and the whole
context I was looking at changes --sometimes without my realizing it.
So I guess I need to be able to read and set the scroll position of
the window to restore it. I don't have a clue how I might be able to
do this. I explored with AutoIt and it can only identify the whole
parameters tab pane as a single item.
Anyone have any ideas?
Thanks,
Dennis
