Richedit TabStops

I am having a problem with setting tabstops in Richedit.
The code is:::

procedure TForm1.SetTabs(Sender: TObject);
begin
     with Richedit1.Paragraph do
          begin
               Tab[0] := 100;
               Tab[1] := 200;
               Tab[2] := 300;
          end;
end;

No matter how many tabs I set, it always leaves off the last one.
This code produces 2 tabstops. After that, they are all default
positions.
If I set 5 tabstops, there are only 4 in the Richedit.
And yes, If I set one, none show up.
They are in the right place just missing one.
The window is created and visible when this code is performed.
Thanks for the help,, Jim

Here is a complex but valuble code snippet I received from Russell L. Smith (Thanx russell) some time ago...It shows how set the tabs in a rich edit etc depending on font and pixels etc...

first add this to your private section

procedure SetTabSize(RichEdit: TRichEdit; TabSize: Integer);

then here is the snippet

procedure TForm1.SetTabSize(RichEdit: TRichEdit; TabSize: Integer);
                            var
                              nSelStart: Integer;
                              tmFont: TTextMetric;
                              nTextFontWidth: Integer;
                              nxLogPixels: Integer;
                              nTabStop: Integer;
                            begin
                              // select the entire memo
                              nSelStart := RichEdit.SelStart;
                              RichEdit.SelectAll;

                              // get the avg pixel width of the rich edit's font
                              with TGraphicControl.Create(Self) do
                              begin
                                Canvas.Font := RichEdit.Font;
                                GetTextMetrics(Canvas.Handle, tmFont);
                                nTextFontWidth := tmFont.tmAveCharWidth;
                                nxLogPixels := GetDeviceCaps(Canvas.Handle, LOGPIXELSX);
                                Free;
                              end;

                              // set ten tab stops
                              RichEdit.Paragraph.Tab[0] := (TabSize - 1) * nTextFontWidth * 72 div
                            nxLogPixels;
                              for nTabStop := 1 to 9 do
                                RichEdit.Paragraph.Tab[nTabStop] := (nTabStop + 1) * TabSize *
                            nTextFontWidth * 72 div nxLogPixels;

                              // deselect
                              RichEdit.SelStart := nSelStart;
                            end;

Hope this helps

This I didn't know.

I did know that TabAlignments and TabKinds are not supported by the RichEd20.DLL to be displayed. (They are loaded and saved though)

Sure it has...after each setting of the tab it returns the last one unless you specify which one to be executed, and when to be executed..
