  13     This class provides pages for wxRichTextFormattingDialog, and allows other
  14     customization of the dialog.
  15     A default instance of this class is provided automatically. If you wish to
  16     change the behaviour of the
  17     formatting dialog (for example add or replace a page), you may derive from this
  18     class,
  19     override one or more functions, and call the static function
  20     wxRichTextFormattingDialog::SetFormattingDialogFactory.

  90     In the constructor, specify the pages that will be created. Use GetStyle
  91     to retrieve the common style for a given range, and then use ApplyStyle
  92     to apply the user-selected formatting to a control. For example:
  93
  94     @code
  95     wxRichTextRange range;
  96         if (m_richTextCtrl-HasSelection())
  97             range = m_richTextCtrl-GetSelectionRange();
  98         else
