def findTopWindows(wantedText=None, wantedClass=None, selectionFunction=None):
    '''Find the hwnd of top level windows.
    You can identify windows using captions, classes, a custom selection
    function, or any combination of these. (Multiple selection criteria are
    ANDed. If this isn't what's wanted, use a selection function.)

    Arguments:
    wantedText          Text which required windows' captions must contain.
    wantedClass         Class to which required windows must belong.
    selectionFunction   Window selection function. Reference to a function
                        should be passed here. The function should take hwnd as
                        an argument, and should return True when passed the
                        hwnd of a desired window.

    Returns:            A list containing the window handles of all top level
                        windows matching the supplied selection criteria.

    Usage example:      optDialogs = findTopWindows(wantedText="Options")
    '''
    results = []
    topWindows = []
    win32gui.EnumWindows(_windowEnumerationHandler, topWindows)
    for hwnd, windowText, windowClass in topWindows:
        if wantedText and not _normaliseText(wantedText) in _normaliseText(windowText):
            continue
        if wantedClass and not windowClass == wantedClass:
            continue
        if selectionFunction and not selectionFunction(hwnd):
            continue
        results.append(hwnd)
    return results
