Retrieving the number of breaks in a FLowLayout

Question

I want to programatically retrieve the number of breaks/newlines in a TFlowLayout.

I have a simple TFlowLayout with 4 regular controls inside (The TFlowLayout does not contain any TFlowLayoutBreak controls).

Depending on the width of the layout it looks like:

// * = control

// Scenario #1: No breaks
* * * *

// Scenario #2: 1 break
* * * 
*

// Scenario #3: 2 breaks
* * 
* * 

// Scenario #4: 3 breaks
*
*
*
*

Is it possible to retrieve the number of breaks of a TFlowLayout programatically or can I only go off the width of the layout to determine the number of breaks?

Counting the changes in Y values for the controls looks to work since the array is in layout order.

procedure TForm1.Button1Click(Sender: TObject);
var
  Cnt, I : integer;
begin
  if FlowLayout1.ControlsCount = 0 then Cnt := 0 else Cnt := 1;
  for I := 1 to FlowLayout1.ControlsCount - 1 do
    if FlowLayout1.Controls[I-1].Position.Y <> FlowLayout1.Controls[I].Position.Y then inc(cnt);
  button1.Text := IntToStr(Cnt);
end;
