I created a Text Area in app designer. It is populated with status messages as the app runs. After a while the area fills with lines of text, and the vertical scroll bar appears, but new messages are written in the invisible part of the area. The user has to scroll down "by hand". How can I make the Text Area autoscroll, so that each new message is visible?

If it's possible to use a listbox instead of a text area, you would be able to use the scroll function to programmatically scroll specific items into view:

Scroll function does not work properly with App Designer List Box, unfortunately:
  • in startFcn it hides the List Box (permanently)
  • in callbacks it does exactly nothing
