Here's Ernest Lötter from ISS International (world leader in microseismological services and software for monitoring of mines) in Stellenbosch, sharing some info about the the NetBeans Platform Visual Library.
However, you need to learn Afrikaans first to understand it! In fact, this is (unless I am mistaken) the first screencast about the NetBeans Platform that is in Afrikaans! (German and Dutch speakers would probably understand the screencast though.)
The whole screencast is less than 5 minutes, it won't take much of your time, so take a quick look:

In summary, Ernest describes an extension to a homework exercise done during the NetBeans Platform Certified Training in Stellenbosch.
