SWT: A Developer's Notebook

Supplying the SWT Package to the Java Compiler

First, you’ve got to let javac know where to find the SWT libraries so that it can compile your applications.

How do I do that?

You first need to create a Java project, and then specify the Java Build Path for that project.

Note

The Java Build Path in Eclipse is the equivalent of specifying the -classpath option for the javac compiler on the command line.

The Java Build Path in Eclipse may be specified either at the time the project is created, or later by selecting Project Properties from the Eclipse menu. Either way, you will invoke a dialog similar to that shown in Figure 1-6, the Project Properties dialog. Select Java Build Path from the list on the left side of the dialog, which will reveal the set of tabs shown in the figure. Click the Libraries tab to specify the SWT packages required for your project.

On the Libraries tab, click the Add External JARs button and use the dialog shown in Figure 1-7 to locate the JAR file that contains the SWT classes (you should have these from Section 1.1 Section 1.1. This file is normally called swt.jar and will be located in the directory where you extracted the SWT development files.

Make sure you include swt.jar ...
