differences between WM_IsCompletelyCovered(), WM_IsCompletelyVisible() and WM_IsVisible()

    I wonder what are the differences between WM_IsCompletelyCovered(), WM_IsCompletelyVisible() and WM_IsVisible().
    For example if I have a hidden window? Or if my window is only partially covered?

    best regards

    Hi,

    WM_IsCompletelyCovered() returns 1 if the window is completely covered by another window.
    WM_IsCompletelyVisible() returns 1 if no part of the window is covered by another window.
    WM_IsVisible() returns 1 if the window is not hidden, even if the window is completely coverd. It will return 0 if you hide it (by calling WM_HideWindow()).

    Regards,
