Delphi-PRAXiS - Delphi Aufzählungszeichen in TRxRichEdit

Hi,

Das TRxRichEdit.Paragraph hat leider nicht alle Members von TParaFormat2 gekapselt.
So lässt sich nicht das wNumberingStart von PARAFORMAT2 nicht direkt setzen.
Musst es so machen:

Delphi-Quellcode:

			var

  fmt: TParaformat2;

begin

  FillChar(fmt, SizeOf(fmt), 0);

  fmt.cbSize := SizeOf(fmt);

  fmt.dwMask := PFM_NUMBERING or PFM_NUMBERINGSTART or PFM_NUMBERINGSTYLE or

                PFM_NUMBERINGTAB;

  fmt.wNumbering := 2;

  fmt.wNumberingStart := 1;

  fmt.wNumberingStyle := $0;

  RxRichEdit1.Perform(EM_SETPARAFORMAT, 0, lParam(@fmt));

end;

Hier der Vollständigkeit halber weitere Members von PARAFORMAT2 und deren Erklärungen:

Delphi-Quellcode:

			uses 

  RichEdit; 

procedure TForm1.Button1Click(Sender: TObject); 

var 

  fmt: TParaformat2; 

begin 

  FillChar(fmt, SizeOf(fmt), 0); 

  fmt.cbSize := SizeOf(fmt); 

  // The PARAFORMAT2 structure is used to set the numbering style. 

  // This is done through the following structure members: 

  fmt.dwMask := PFM_NUMBERING or PFM_NUMBERINGSTART or PFM_NUMBERINGSTYLE or 

                PFM_NUMBERINGTAB; 

      // Set the following values (bitwise-or them together) to identify 

      // which of the remaining structure members are valid: 

      // PFM_NUMBERING, PFM_NUMBERINGSTART, PFM_NUMBERINGSTYLE, and PFM_NUMBERINGTAB 

  fmt.wNumbering := 2; 

      //0 no numbering or bullets 

      //1 (PFN_BULLET) uses bullet character 

      //2 Uses Arabic numbers (1, 2, 3, ...). 

      //3 Uses lowercase letters (a, b, c, ...). 

      //4 Uses uppercase letters (A, B, C, ...). 

      //5 Uses lowercase Roman numerals (i, ii, iii, ...). 

      //6 Uses uppercase Roman numerals (I, II, III, ...). 

      //7 Uses a sequence of characters beginning with the Unicode 

      //  character specified by the wNumberingStart member. 

  fmt.wNumberingStart := 1; 

      //  Starting value for numbering. 

  fmt.wNumberingStyle := $200; 

      // Styles for numbering: 

      // 0 : Follows the number with a right parenthesis.  1) 

      // $100 : Encloses the number in parentheses.       (1) 

      // $200 : Follows the number with a period.          1. 

      // $300 : Displays only the number.                  1 

      // $400 : Continues a numbered list without applying the next number or bullet. 

      // $8000 : Starts a new number with wNumberingStart. 

  fmt.wNumberingTab := 1440 div 4; 

  // Minimum space between a paragraph number and the paragraph text, in twips 

  RichEdit1.Perform(EM_SETPARAFORMAT, 0, lParam(@fmt)); 

end;
