In order to get the text of selected TreeItems from a Tree in SWT you can use the following method.

The Tree class already offers a nice function getSelection() which returns an array holding all selected TreeItems.

In case you need to show some web pages in an embedded browser in a Java Rich Client application you can use an SWT component of Eclipse.

This makes it quite easy, if you cannot use JavaFX 2.0 yet in order to do the trick because the client computers are running on older Java versions.
