Eclipse - Standard Widget Toolkit (SWT) - Installation
SWT, the Standard Widget Toolkit, will help us to draw windows for the Java platform.
On this webpage you will find links to download last stable releases http://www.eclipse.org/swt/
Once downloaded, open Eclipse, right click on the Explorer tab, then : Import... > General > Existing Projects into Workspace.
Click Next then select the Select archive file option and browse until, for example for Windows OS, your swt-3.7.1-win32-win32-x86.zip file.
Click Finish.
Now in your Package Explorer you can see the org.eclipse.swt project.
Right click in this Explorer to create a new Java project named for example project1.
Right click on project1 > Build Path > Configure Build Path > Java Build Path.
On the right there are several tabs.
Select Projects and click Add...
Select org.eclipse.swt and click OK.
You project project1 is now linked with SWT and you can use its classes.

HelloWorldSWT which is the 1st example of SWT given after the installation of Eclipse does not work on Windows (I just tested it on Seven).
Yypically you get those errors:
Exception in thread "main" java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons:
no swt-win32-3738 in java.library.path
no swt-win32 in java.library.path

After the download of swt-3.7.1-win32-win32-x86.zip and by following the above given explanations by Mi-K, it just works.
By the way you can find swt-3.7.1-win32-win32-x86.zip for example here:

Hi, it does not works now.
Eclipse says "Some projects cannot be imported because they already exist in the workspace". Please, help!

Hello Kostyanus,
Hello Kostyanus,
Just rename your project with another name or delete it from your computer.
