org.eclipse.swt

Main plug-in for the SWT user interface library.

Setting the classpath:

To compile this project, you need to set the classpath specific for your operating and windowing system. For this, rename one of the following files to .classpath:

• .classpath_win32 - Windows
• .classpath_cocoa - Mac OS X
• .classpath_gtk - Linux and all Unix variants

To see these files, you may have to remove the filter for “.* resources”:

• In the Project Explorer: view menu > Customize View... > Filters
• In the Package Explorer: view menu > Filters...

Dependencies:

You also need to clone the https://git.eclipse.org/r/#/admin/projects/platform/eclipse.platform.swt.binaries Git repository and ensure that the fragment matching your windowing_system.operating_system.cpu_architecture (e.g. org.eclipse.swt.gtk.linux.x86_64) is open in your workspace. The fragments provide the platform-specific native libraries.

Using Assertions:

Assertions are added to the code. These don't run in production, but they do when:

• JUnits are ran, they turn on assertions by default.
• If you run a java run configuration and add ‘-ea’ to the ‘VM Arguments’

Assertions look like:

assert expression ;
assert expression : msg ;
