Hi all,

I need a SpeedButton whith ability to execute OnClick event procedure repetitively while in Down position.
I've tried with Timer checking if SpeedButton.Down property is True, but it doesn't work.
I suppose there is some smart way to do it using standart component TSpeedButton, but don't know it.

Try this:

procedure TForm1.SpeedButton1MouseDown(Sender: TObject;
  Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
begin
  //Start the timer
  Timer1.Enabled := TRUE;
end;

procedure TForm1.SpeedButton1MouseUp(Sender: TObject; Button: TMouseButton;
  Shift: TShiftState; X, Y: Integer);
begin
  //End the timer
  Timer1.Enabled := FALSE;
end;

procedure TForm1.SpeedButton1Click(Sender: TObject);
begin
  //Do what we need to do
  Label1.Caption := IntToStr(iCount);
end;

procedure TForm1.Timer1Timer(Sender: TObject);
begin
  iCount := iCount + 1;
  //Force a 'click'
  SpeedButton1Click(Self);
end;

This works fine for me. The code runs, and increments (and displays) iCount, putting the results into Label1.

Did you have the interval on your TTimer set correctly? In my code it's set to 100

Hi Fatman,

Set AllowAllUp to true and GroupIndex to 1. Then the timer will work.

Regards, Geo
