And, the other thing about this is, make sure the window you want really
does stay in the same position in the hierarchy. Dynamic environments can
some times change those relationships, so be ware.
I find the GetWindowHierarchyX and y functions to be a bit misleading,
because, as Doug tried to explain, two numbers, x and y don't really get you
there. They don't contain enough information to uniquely define the window.
It's more like a set of directions, that start at the top of the tree, and
go down. Each time you descend one window, you need to decide, now do I
need to move along to the nth peer on this level, or can I just use the
first child. Each time you descend, you need to consult the driving
directions, and see if you need to move among peers like that before you
descend. Maybe you know you are going to descend. You are just not sure
which peer you should descend from.
Instead of a simple x, y identification. It is more a long list of driving
directions, one for each level. And, a "direction" would say how many times
you need to call GetNextWindow on the current level to find the proper
window from which to make your next descent.
Looks like two nested loops. One to descend a level, and the innner loop to
move among peers.

Using hierarchical position to find a window is a bit time-consuming
if you're trying to get to it, but a bit less if you're just trying
to identify a window you already have.
GetWindowHierarchyX(hwnd) and GetWindowHierarchyY(hwnd) will give
you an idea where a window can be found in the hierarchy, provided
you already have a window handle. The trick here, though, is that
you need the GetWindowHierarchyX value for each level from that
window up to the top, if you want to find the window again later.
I say it's time-consuming to find the window later because there's no
function in JAWS scripting to go straight to the nth window at a
level, so you have to loop once for each level until you get to the
right window for that level.
In physical terms, it's like this: I'm hiding out on a leaf.
GetWindowHierarchyY tells you I'm four branch splits from the tree
trunk, and getWindowHierarchyX tells you I'm the third leaf on my
branch. The problem is, you don't know where my branch is on the
branch it comes from, or where that one is on the one it comes from,
etc. You need something like, "Go to the second branch from the trunk,
then the fifth branch from that one, then the second branch from that,
and then the third leaf on that one." This takes a bit of doing in
JAWS.

Thanks Dug for responding. I do get what you are saying. I was hoping I
could maybe find the descendent window by its position in the hierarchy and
then grab its handle from there. This may not have been clear from my
original request.
Maybe this is more clear. Its may be just to cumbersome to be practical as
well.

What I'm about to say is honestly not meant to sound flippant, but I'm still
afraid it might:
Most any search tactic will require that you know what you're looking for,
so I'm having trouble identifying specifically what is troubling you.
FindDescendantWindow requires a control ID. I find useful and unique control
IDs rather scarce these days, so I usually use FindWindow instead, as it can
search by window class name, window name, or both at once. If your
application sports unique and consistent control Ids, you can use
findDescendantWindow to good advantage though.

Hi, I have been trying to figure out how to find a specific descendent
window based on higharchy but haven't clude in yet. FindDescendentWindow
requires that you know what you are looking for so this does not work for
me.
Can any one point me in the right direction?
Thanks
