    @class wxRichMessageDialog

    Extension of wxMessageDialog with additional functionality.

    This class adds the possibility of using a checkbox (that is especially
    useful for implementing the "Don't ask me again" kind of dialogs) and an
    extra explanatory text which is initially collapsed and not shown to the
    user but can be expanded to show more information.

    Notice that currently the native dialog is used only under MSW when using
    Vista or later Windows version. Elsewhere, or for older versions of
    Windows, a generic implementation which is less familiar to the users is
    used. Because of this it's recommended to use this class only if you do
    need its extra functionality and use wxMessageDialog which does have native
    implementation under all platforms otherwise. However if you do need to put
    e.g. a checkbox in a dialog, you should definitely consider using this
    class instead of using your own custom dialog because it will have much
    better appearance at least under recent Windows versions.

    To use this class, you need to create the dialog object and call
    ShowCheckBox() and/or ShowDetailedText() to configure its contents.
    Other than that, it is used in exactly the same way as wxMessageDialog and
    supports all the styles supported by it. In particular, ShowModal() return
    value is the same as for wxMessageDialog. The only difference is that you
    need to use IsCheckBoxChecked() to examine the checkbox value if you had
    called ShowCheckBox().

    Here is a simple example:
    @code
    void MyFrame::ShowDialog()
    {
        if ( ... shouldn't show this dialog again ... )
            return;

        wxRichMessageDialog dlg(this, "Welcome to my wonderful program!");
        dlg.ShowCheckBox("Don't show welcome dialog again");
        dlg.ShowModal(); // return value ignored as we have "Ok" only anyhow

        if ( dlg.IsCheckBoxChecked() )
            ... make sure we won't show it again the next time ...
    }
    @endcode
