Pywinauto - How to wait on specific window title changed among windows with equal windows attributes

Question

In application I create some instances of the same form (all windows attributes besides handle are the same) and work with them independently. During session form changes own title depending on context, I need to wait title changing after certain operations in form.

Next code, don't wait and get window immediately before title changed:

w = app.window(handle = handle, title_re = '...', class_name='...')
w.wait('ready', timeout = 2)

due to work features of function find_elements():

if handle is not None:
    return [backend_obj.element_info_class(handle), ]

So, what the best solution for it?

P.S. some forms I need to speed up execution, it's important

Of course I can use next code:

def check_state():
    windows = app.windows(title = '...', class_name='...')
    for w in windows:
        if handle == w.handle:
            return(True)
    return(False)

pywinauto.timings.wait_until(5, 0.5, check_state, True)

Is it the best solution or probably I skipped something else?

Answer 1

Yes, function timings.wait_until(...) is good enough for this purpose. Methods .wait() and .wait_not() are limited to a window specification only. wait_until is generic one.

Also search criterion found_index=i can be useful in .window(...)/.child_window(...) specification.
