B4J Question Invalidate functionality

[ValDog]

After drawing something on a panel in B4A we would use something like:

Panel.Invalidate

to force a re-paint. How do we do that in B4J?

You don't need to invalidate the view. The drawing will appear immediately.

Erel, thanks - I later got that to work. Question is though, if I am plotting real time measurements I guess I would need to clear the display and redraw the entire curve. What's the best way to do that?

You can use Canvas.ClearRect or DrawRect to clear the canvas.

Erel, thanks!

ClearRect works like a charm!!
