/**
    @class wxFindReplaceDialog

    wxFindReplaceDialog is a standard modeless dialog which is used to allow the

    The actual searching is supposed to be done in the owner window which is the
    parent of this dialog. Note that it means that unlike for the other standard
    dialogs this one @b must have a parent window. Also note that there is no
    way to use this dialog in a modal way; it is always, by design and
    implementation, modeless.

    Please see the @ref page_samples_dialogs sample for an example of using it.
