I've been putting of writing this part because it's complicated and it involves a bunch of programming that does not directly apply to Orbiter. That said I really need to post something before my "in-progress point" goes too much further, so without further ado...

PART 13: Classes and Objects
In C++ a class is an expanded concept of a data structure that can hold both data and functions. An object is specific instance of a class. In terms of variables, a class would...

Orbiter 2010 introduces a new way to define 2-D panels. Documentation for this is still thin on the ground (but under development), and currently only the stock DG provides an example for it.

I thought that maybe a small tutorial series may be the way to nudge developers towards adopting the new style. So here goes ...

Why should I switch to the new interface?
The new panel style has a number of advantages over the legacy (2006) method:

• It is better supported

...

So, I thought I'd make a short tutorial covering panels in vessel modules. I'm currently adding a panel to EOP, so I'll use it as an example.

Part 1: Preparing the Panel

1. First, get a panel drawn. I'm using wehaveaproblem's panel that he drew specifically for EOP. I'd reccomend you make the dimensions 1024 x 768, as this is compatible with most resolutions.

2. Bring the panel to the bottom of the image, and leave the rest white:
