How can I define the length of each Tabstop
in a TRichedit?
The predefined Tabstops are to wide for my application,
so i would like to decrease them.
Example:


Example Line
________Here we´re at 1st tab________ Here we 2nd tab

but i want to have something like

Example Line
___Here we´re at 1st tab___Here we 2nd tab

Thanks!

You should send the message EM_SETPARAFORMAT.

uses richedit
procedure....
var FFormat: TPARAFORMAT;
begin
//set the FFormat values
with FFormat do
begin
.
.
cTabCount:=...
rgxTabs:=...
end;
RichEdit1.Perform(EM_SETPARAFORMAT,0,FFormat);
end;

This is the complete example for the
setTAB procedure (done with the help of ronit´s answer):

var FFormat: TParaformat;

begin
 with FFormat do
  begin
   FillChar(FFormat, SizeOf(TParaFormat), 0);
   cbSize := SizeOf(TParaFormat);
   cTabCount:=4;
   rgxTabs[0]:=5;
   rgxTabs[1]:=15;
   rgxTabs[2]:=25;
   rgxTabs[3]:=40;
 end;
 Richedit1.Perform(EM_SETPARAFORMAT,0,LPARAM(@FFormat));
end;

but anyway, with the help of ronit´s EM_SETPARAFORMAT
i found that this setTab procedure is already wrapped into
delphi. So here´s an easier solution ;)

 Richedit1.SelectALL; {* Select all paragraphs *}

 RichEdit1.Paragraph.tab[0]:=5;
 RichEdit1.Paragraph.tab[1]:=15;
 RichEdit1.Paragraph.tab[2]:=25;
 RichEdit1.Paragraph.tab[3]:=35;
 RichEdit1.Paragraph.tab[4]:=45;

 RichEdit1.Sellength:=0; {* deselect *}

The .tab property calls (if written) the SetTab proc of
TParaAttributes, which does nearly the same as the above procedure ;)

Thanks for your help Ronit!
