    This class provides pages for wxRichTextFormattingDialog, and allows other
    customization of the dialog.

    A default instance of this class is provided automatically.
    If you wish to change the behaviour of the formatting dialog (for example add
    or replace a page), you may derive from this class, override one or more
    functions, and call the static function
    wxRichTextFormattingDialog::SetFormattingDialogFactory.

/**
    @class wxRichTextFormattingDialog

    This dialog allows the user to edit a character and/or paragraph style.

    In the constructor, specify the pages that will be created.
    Use wxRichTextFormattingDialog::GetStyle() to retrieve the common style
    for a given range, and then use wxRichTextFormattingDialog::ApplyStyle()
    to apply the user-selected formatting to a control.

    For example:
    @code
        wxRichTextRange range;
        if (m_richTextCtrl-HasSelection())
            range = m_richTextCtrl-GetSelectionRange();
        else
            range = wxRichTextRange(0, m_richTextCtrl-GetLastPosition()+1);

        int pages = wxRICHTEXT_FORMAT_FONT|wxRICHTEXT_FORMAT_INDENTS_SPACING| \
                    wxRICHTEXT_FORMAT_TABS|wxRICHTEXT_FORMAT_BULLETS;

        wxRichTextFormattingDialog formatDlg(pages, this);
        formatDlg.GetStyle(m_richTextCtrl, range);

        if (formatDlg.ShowModal() == wxID_OK)
