I'm running a RichView component with formatted text.

When certain events are triggered the text would be regenerated and then

scrolls back to the old position. (To make text look like it updated without

moving)

eg:

var

  scroll:Integer;

scroll := richview1.VScrollpos;

redoView;  //Changes the text in richview1

richview1.format;

richview1.VScrollPos := scroll;

richview1.repaint;

The text scrolls to its old position fine, but it flickers since the editor(and

scrollbar) moves to the top, then jumps down to its old position again.

Is there a way to update the text and move the scrollbar back down without

refreshing the component (so visually its still showing the old text), and

once all that is done do one refresh to make it show the new text with it

scrolled in the correct position already?

Thanks for the help
