SWT 3.2

SWT is an open source widget toolkit for Java designed to provide efficient, portable access to the user-interface facilities of the operating systems on which it is implemented.

Full-blown examples that can be downloaded from the eclipse download page. The examples in package org.eclipse.swt.examples run standalone, and the examples in org.eclipse.swt.examples.* packages are eclipse plug-ins.

To get the examples, first go and watch to the eclipse download page:
http://download.eclipse.org/downloads/index.php
Then click on the eclipse build that you would like examples for (i.e. the eclipse build that you are running; typically the latest Stable Build).
Then scroll down until you see "Example Plug-ins". Read the paragraph on installing them, and select the download for your platform.
After installing the examples, the source for them will be in a src.zip file in the appropriate subdirectory of: eclipse/plugins/org.eclipse.sdk.examples.source_ /src/
For example, the 3.1 source for the standalone examples in org.eclipse.swt.examples is in: org.eclipse.sdk.examples.source_3.1.0/src/org.eclipse.swt.examples_3.1.0/swtexamplessrc.zip.
To run the plug-in SWT examples, restart eclipse, go to Window > Show View... > Other... and expand "SWT Examples".
