You can use the event BeforeInitializePar to update the current paragraph:

 

procedure TForm1.WPRichText1BeforeInitializePar(Sender: TObject;

 RTFEngine: TWPRTFEngineBasis; RTFDataBlock: TWPRTFDataBlock;

 par: TParagraph);

var pos_wstart, i : Integer; s : string;

begin

// Current paragraph

  // Current paragraph

if par = WPRichText1.ActivePar then

begin

    i := WPRichText1.ActivePosInPar;

    // 1. Overread spaces to the left

    while (i>0) and par.IsSpace(i) do dec(i);

 

    // 2. Overread a word

    pos_wstart := -1;

    if not par.IsWordDelimiter(i) and (par.IsSpace(i+1)) then

    begin

        while (i>=0) and not par.IsWordDelimiter(i) do begin pos_wstart := i; dec(i); end;

        // 3. Overread spaces

        while (i>0) and par.IsSpace(i) do dec(i);

 

        // Now, if . ! ? or start of par uppercase it!

        if  (pos_wstart>=0) and

            ((i<=0) or  (par.CharItem[i]='.') or

                     (par.CharItem[i]='!') or

                     (par.CharItem[i]='?'))

            // Check for abbreviation (simplified - only check a..z

            and ((par.IsSpace(i-1) or (par.CharItem[i]<>'.') or

                 ((par.CharItem[i-1]>='a') and (par.CharItem[i-1]<='z'))))

            then

          begin

              if Integer(par.CharItem[pos_wstart])<256 then

              begin

                     s := AnsiUpperCase(Char(par.CharItem[pos_wstart]));

                    if s<>'' then par.CharItem[pos_wstart] := WideChar(s[1]);

              end

              else  par.CharItem[pos_wstart] := WideUpperCase(par.CharItem[pos_wstart])[1];

          end;

    end;

end;

end;
