In VCL you can call the TeeCommander buttons manually to activate the different features by code.

It would be interesting to allow this in ActiveX too.

In VCL you can do this:

procedure TForm1.FormCreate(Sender: TObject);
begin
  TeeCommander1.Hide;
end;

procedure TForm1.MoveButtonClick(Sender: TObject);
begin
  TeeCommander1.ButtonMove.Click;
  TeeCommander1.ButtonMove.Down:=True;
end;

procedure TForm1.DepthButtonClick(Sender: TObject);
begin
  TeeCommander1.ButtonDepth.Click;
  TeeCommander1.ButtonDepth.Down:=True;
end;

procedure TForm1.ZoomButtonClick(Sender: TObject);
begin
  TeeCommander1.ButtonZoom.Click;
  TeeCommander1.ButtonZoom.Down:=True;
end;
