    using a permanent wxRichTextStyleComboCtrl or wxRichTextStyleListCtrl to
    present styles.

    /**
        Constructor.

        To create a dialog, pass a bitlist of @a flags (see below), a style sheet, a
        text control to apply a selected style to (or @NULL), followed by the usual
        window parameters.

        To specify the operations available to the user, pass a combination of these
        values to @e flags:

        - @b wxRICHTEXT_ORGANISER_DELETE_STYLES: Provides a button for deleting styles.
        - @b wxRICHTEXT_ORGANISER_CREATE_STYLES: Provides buttons for creating styles.
        - @b wxRICHTEXT_ORGANISER_APPLY_STYLES: Provides a button for applying the
                                                currently selected style to the selection.
        - @b wxRICHTEXT_ORGANISER_EDIT_STYLES: Provides a button for editing styles.
        - @b wxRICHTEXT_ORGANISER_RENAME_STYLES: Provides a button for renaming styles.
        - @b wxRICHTEXT_ORGANISER_OK_CANCEL: Provides OK and Cancel buttons.
        - @b wxRICHTEXT_ORGANISER_RENUMBER: Provides a checkbox for specifying that
                                            the selection should be renumbered.

        The following flags determine what will be displayed in the style list:

        - @b wxRICHTEXT_ORGANISER_SHOW_CHARACTER: Displays character styles only.
        - @b wxRICHTEXT_ORGANISER_SHOW_PARAGRAPH: Displays paragraph styles only.
        - @b wxRICHTEXT_ORGANISER_SHOW_LIST: Displays list styles only.
        - @b wxRICHTEXT_ORGANISER_SHOW_ALL: Displays all styles.

        The following symbols define commonly-used combinations of flags:

        - @b wxRICHTEXT_ORGANISER_ORGANISE:
          Enable all style editing operations so the dialog behaves as a style organiser.
        - @b wxRICHTEXT_ORGANISER_BROWSE:
          Show a list of all styles and their previews, but only allow application of a
          style or cancellation of the dialog. This makes the dialog behave as a style browser.
        - @b wxRICHTEXT_ORGANISER_BROWSE_NUMBERING:
          Enables only list style browsing, plus a control to specify renumbering.
          This allows the dialog to be used for applying list styles to the selection.
