Doug,
Are you saying not all Window object can derive a Control object? I've
not see that if that is the case. But I have seen that the Next and
Previous properties of a Control don't always return an object. Usually
that means it is an overlap window or something. but if you are talking
about all the controls in a dialog this should work fine.

Yes this is very helpful info. The only remaining concern I can see
is that my coworker, Jon, reports that not all windows have .control
objects associated with them.

Then yes, the Window.Control.Previous and Window.Control.Next will get
you the previous and next window in Z order (also commonly referred to
as tab order). In fact when you use these properties, Window-Eyes
simply calls the GetWindow function with either GW_HWNDPREV or GW_HWNDNEXT.
You may also be able to use the Window.Control.Taborder property to also
help you...
Does this help?

I don't know my coworker's exact use case, but one I can think of is
when a control in focus is predictably labeled by the control prior to
it in Z order, or the prior Static control in Z order, or less
commonly, by the prior Static to the focused control's parent or
grandparent. Screen readers sometimes automate this sort of tree
search because these algorithms have proven effective in enough cases
I guess. I've run into the need for this sort of thing quite often in
JAWS scripting, though off the top of my head I don't know how many of
those instances would have been adequately addressed by just a loop
through directChildren.

Hello Doug L,
Regarding your Z order question... Can you give me a specific example
what you are needing this for? Maybe that would help us give you a
better idea of what you can currently do or something we could add in
the future.
Thanks,
Doug G

We're looking for a reliable way to get the next and previous window
in Z order from a given window. It might sometimes also be useful
to get the first and last window in Z order at the given window's
tree level. The Windows API GetWindow() function allows this sort
of query, and there are WinAPI functions for next and prior window,
but I don't see a direct way to do it in Window-Eyes. I'm betting
I missed something obvious.
My two ideas are
' Given window, the one to start from ...
dim nextWindow, priorWindow
' Idea 1.
set nextWindow = window.control.next.window
set priorWindow = window.control.previous.window
' Idea 2.
dim windows : set windows = window.parent.directChildren
dim i
for i = 1 to windows.count
if windows(i).handle = window.handle then
set nextWindow = windows(i+1)
set priorWindow = windows(i-1)
end if
next
Plus error checking of course.
But I don't know if control.next/previous or directChildren sort by Z
order, so I'm not sure if one approach is more accurate than the other.
I'm also assuming that window.control is always valid for all Window
objects here.
Is there a better way of doing this, and if not, is the
window.control.next/previous.window method the preferred way of doing it?
