  it seems gapx creates an indent from left AND right side independent from text-alignment!

  Yes, this is expected behavior

  but this doesn't make sense (for me). I need an alternative behavior. Where can I modify thisin the sources?

  Search for GapX in the frxClass.pas

  solved:
  

  procedure TfrxCustomMemoView.BeginDraw(Canvas: TCanvas; ScaleX, ScaleY, OffsetX, OffsetY: Extended);
  var
    bx, by, bx1, by1, wx1, wx2, wy1, wy2, gx1, gy1: Integer;
  begin
    inherited BeginDraw(Canvas, ScaleX, ScaleY, OffsetX, OffsetY);
    wx1 := Round((Frame.Width * ScaleX - 1) / 2);
    wx2 := Round(Frame.Width * ScaleX / 2);
    wy1 := Round((Frame.Width * ScaleY - 1) / 2);
    wy2 := Round(Frame.Width * ScaleY / 2);
    bx := FX;
    by := FY;
    bx1 := FX1;
    by1 := FY1;
    if ftLeft in Frame.Typ then
      Inc(bx, wx1);
    if ftRight in Frame.Typ then
      Dec(bx1, wx2);
    if ftTop in Frame.Typ then
      Inc(by, wy1);
    if ftBottom in Frame.Typ then
      Dec(by1, wy2);
    gx1 := Round(GapX * ScaleX);
    gy1 := Round(GapY * ScaleY);
   // GapX-Position in relation to current HAlign 
    case HAlign of
      haCenter,
      haBlock  : FTextRect := Rect(bx + gx1, by + gy1, bx1 - gx1 + 1, by1 - gy1 + 1);
      haLeft   : FTextRect := Rect(bx + gx1, by + gy1, bx1 + 1, by1 - gy1 + 1);
      haRight  : FTextRect := Rect(bx, by + gy1, bx1 - gx1 + 1, by1 - gy1 + 1);
    end;
  end;
