Hi,
I am newbie
In page http://www.javadocexamples.com/java_source/org/eclipsebook/c h07/Ch07_03.java.html from 2004 on Eclipse 3.5.1 (nowadays)
I try the example, saying for Composite: "can not instantiate the type Composite"
Can't I trust the book?
How can I do?

Are you sure your code is identical to the code in the example, or did you get
different imports? There are a lot of types named "Composite" and some of them
are interfaces instead of classes; the one you want is
org.eclipse.swt.widgets.Composite. So make sure that your import statements
match those in the example.

Six years is a long time in software, so it is possible that you will find some
things out of date in that book. But I don't think this is one of them.

By the way, the eclipse.newcomers forum is a good place for 'newbie' :-) questions.

OK, thanks.
It came that I had included it from Swing instead of Awt.
