title: What is the equivalent OnScroll Event to TScrollBar for FMX?
body: <p>I have not come across a solution for an Event (OnScroll) handler for a TScrollBar under Delphi 10 Seattle. I chose it because it is not a TScrollBox for which I will put any content into (like a Panel or DBGrid). It is merely going to detect the mouse action (None of the MouseUp/Down/Side-to-Side have worked either) and it is going to be used as file seek tool for which it will force a bunch of TeeCharts to update, based on the direction of the scroll.</p>
  
  <p>So far I have only come across incomprehensible examples consisting of WindowsMessages (WM_HScroll) and VLC.StdCtrls.TScrollBar.OnScroll</p>
  
  <p>What is the efficient way to detect the ScrollBar moving besides OnChange?</p>
  
  <p>It would help to be able to manipulate the ScrollBar and have it reset itself in the middle. Much like it would if I set the value much like if I set the Min = -50 and Max = 50 (0)</p>
