TCustomRichView.AddNL, AddNLA, AddNLW, Add

Top  Previous  Next

These methods add one text item with the StyleNo-th text style and the ParaNo-th paragraph style, with the specified Tag to the end of document.

procedure AddNL(const s: String; StyleNo: Integer; ParaNo: Integer = -1;

  const Tag: TRVTag = RVEMPTYTAG);
procedure AddNLW(const s: TRVUnicodeString; StyleNo, ParaNo: Integer;

  const Tag: TRVTag = RVEMPTYTAG);
procedure AddNLA(const s: TRVAnsiString; StyleNo, ParaNo: Integer;
  const Tag: TRVTag = RVEMPTYTAG);

procedure Add(const s: String; StyleNo:Integer);

(introduced in version 1.3 and 1.4; changed in version 18)

Parameters:

s is a text string to add.  It must not contain CR, LF, TAB, FF characters (#13, #10, #9, #12). To add several lines of text use AddTextNL.

StyleNo is an index in the TextStyles collection of the linked RVStyle component, or rvsDefStyle constant. It defines font attributes for the text.

If ParaNo=-1, the methods add an item to the end of the last paragraph. If ParaNo>=0, this item starts a new paragraph using attributes defined in Style.ParaStyles[ParaNo].

Tagtag of this text item.

 

Add provides subsets of functionality of AddNL: Add(...) is equivalent to AddNL..., -1, '').

Note: TRichView allows empty text strings only in empty paragraphs (may be with list makers). See Valid documents.

unicode Unicode notes:

Internally, text is stored as Unicode. AddNLA (and AddNL in non-Unicode versions of Delphi) converts ANSI to Unicode. A code page for conversion is calculated basing on Style.TextStyles[StyleNo]. Charset. If it is equal to DEFAULT_CHARSET, and for non-text items, Style.DefCodePage is used.

Methods type: viewerstyle viewer-style

If style templates are used, the component may automatically change text style indices of text items, to provide a consistency of text and paragraph style templates.
