I am trying to create a paint component for the panel_1
JPanel
, but I don't know how to do it. This is my class.
This code works, except that it does not paint the panel_1
.
If I try and add it to the panel without painting it, it works just fine.
Also I need that panel to refresh (repaints) automatically at a given interval.
Please let help me. :D

Of course the handler is not relevant in this case since I am only interested in painting that panel.
