Basket using SWT and Java?

Late-bound COM automation can be tedious to code in C#! In case it's
helpful, the EdSharp source code (within EdSharp.cs) includes a Com
class that makes things a bit easier. In your example, try using the
BindingFlags.SetProperty constant instead.
By the way, you seem to have done more WPF programming with a screen
reader than anyone I know. Would you consider writing a "fruit basket"
program that illustrates this framework?
As you may know, folks on the list ProgrammingBlind@xxxxxxxxxxxxx
developed a set of criteria for a sample GUI program, and have
encouraged its implementation in various languages. This allows someone
considering a language to get a sense of what coding in it is like and
what the resulting accessibility might be of a program. The web site
with criteria and implementations is
