Tabs

Tabs are used to organize the text in table-like layout. This would not be a real layout table, but will make the text (if it's short enough) to look table alike.

Basics

In order for tabs to work the text should be split tab character (#9)

This is how the text would look like if no tab separation is used:

  RichMemo1.Lines.Add('hello world'); 
  RichMemo1.Lines.Add('this sample');


If the words are split by Tabs, then the control tries to find the next proper tab offset in order:

  RichMemo1.Lines.Add('hello'#9'world'); 
  RichMemo1.Lines.Add('this'+#9+'sample');

Tab Offsets

The length of tab offsets can be controlled using GetParaTabs and SetParaTabs methods.

var
  st : TTabStopList;
  i  : integer;
begin
 
  RichMemo1.GetParaTabs(0, st); // getting the current tabs
  st.Count:=8;
  SetLength(st.Tabs, st.Count);
  for i:=0 to length(st.Tabs)-1 do
    st.Tabs[i].Offset:=i*72;
  RichMemo1.SetParaTabs(-1,-1,st); // assigning tabs stops
 
  // assigning text with tabs (#9)
  RichMemo1.Lines.Add('hello'#9'world'#9'to'#9'columns');
  RichMemo1.Lines.Add('does'#9'it'#9'look'#9'good'#9'?');
  RichMemo1.Lines.Add('tab'+#9+'is'+#9+'character'+#9+'9');
end;
