How to make in Delphi so that gradually, over time, the progressBar position increases?

How to make it so that when you press a button, the progressbar position increases, for example, by 5%? That is, in order for the progress bar position to be 100, you need 20 button presses.

  1. Gradually over time: Need 1 timer. Put the desired time interval: Timer1.Interval: = 1000; // 1000 = 1 second (10,000 - 10 seconds).

Double click on the timer (when it is triggered):

 ProgressBar1.Position:= ProgressBar1.Position + 5; // каждую секунду (1000) - увеличивается на 5.
  1. When you click on Button:

ProgressBar1.Position: = ProgressBar1.Position + 5; // 20 clicks - and here you are 100%

Those. same as the timer.

    Here is an example of how the ProgressBar works by timer:

      procedure TForm3.Timer1Timer (Sender: TObject);
 begin
   ProgressBar1.Position: = ProgressBar1.Position + 1;
   If (ProgressBar1.Position = ProgressBar1.Max) Then
     Timer1.Enabled: = False;
 end;

      You can move the ProgressBar without the position = position + 1 expression, just use StepIt; Those. Form1.ProgressBar.StepIt; The default step is 1, if I'm not mistaken. You can change it like this: Step: = your value. For example, Step: = 5;
