This article explains how to develop and implement trees in the Standard Widget Toolkit. Learn how an SWT tree is created and populated with data, how columns can be used to categorize data, how a tree can be extended to support row sorting, and how the tree's content can be searched.

show what ?
Anyway, I don't like Java and its speed disaster.
Some years I heard about an OS written in Java, still alive ? XD
C++ is for robust things, Python is for prototyping this is the best combination !

Look at Jython. They have an excellent tree example. I wrote jython viewer that connects to a database with hierarchical information in like 10 lines (clean and clear) of code. It just showed me the tree structure and printed information when you selected a node.

Speed disaster? Come on, please be correct. Java was slow in the beginning of its release. Current JIT compilers are as fast as C++ / native code or even faster in some cases.
Why do you think NASA is using Java instead of C++? Because of pointer bugs. Its not reliable enough.

There's no point going into a Java vs C++ argument here -- the question is one of toolkit design. Qt is an exceptionally well-designed toolkit (and has Java bindings, remember), but not everyone is fortunate enough to be in a position to use it, and in some situations it may not be appropriate.
Personally, I disliked the design of both the SWT and Swing toolkits when we studied them at university, but if I were required to write something using SWT, this article would be useful, so good job!
Now how about a series of articles comparing widget toolkits -- Qt, GTK, wxWidgets, FLTK, etc...?

But seeing that it deal with Java SWT, Beeuuuu :-*
I will implement it in Qt anyway, this night and in C++.
(maybe python who knows !)
So whats wrong with Java according to you?
Or you just want to show off that you can hack something in C++?
