Title: Adjusting the tab location in a TMemo component
Question: How can I adjust the tab location in a TMemo component?
Answer:
Send a EM_SETTABSTOPS message to the Memo control. The following
example sets the first 5 tab stops to 20 pixels.
Example:
procedure TForm1.FormCreate(Sender: TObject);
var
DialogUnitsX : LongInt;
PixelsX : LongInt;
i : integer;
TabArray : array[0..4] of integer;
begin
Memo1.WantTabs := true;
DialogUnitsX := LoWord(GetDialogBaseUnits);
PixelsX := 20;
for i := 1 to 5 do begin
TabArray[i - 1] :=
((PixelsX * i ) * 4) div DialogUnitsX;
end;
SendMessage(Memo1.Handle,
EM_SETTABSTOPS,
5,
LongInt(@TabArray));
Memo1.Refresh;
end;
