DesktopSupport Library for Java

This library bridges the Apple Java Extensions APIs and the JEP 272 desktop APIs added in Java 9. It is intended for use by applications that want to support running on both Java 8 and Java 11.

• Apple Java Extensions
• Apple Java Extensions Javadoc
• JEP 272: Platform-Specific Desktop Features

Implementation

This library wraps a subset of the com.apple.eawt.Application API and delegates to whichever actual implementation is available: Apple or Java 9+, or a dummy no-op implementation if neither.

Thus it is safe to call the API anywhere, without checking the platform first. Note, however, that listeners and handlers will never be called under the no-op implementation, so critical logic must not be placed there.

Java version	Platform	Implementation
Java 8	macOS	com.apple.eawt.*
Java 8	Other	No-op
Java 11	Any	java.awt.*

Coverage

• Non-deprecated methods on com.apple.eawt.Application
• Methods on com.apple.eawt.FullScreenUtilities
• UIManager#createLookAndFeel from Java 9+

Requirements

Java 8+ is required to run.

Java 11 is required in order to build.

Usage

Add the dependency:

implementation 'org.madlonkay:desktopsupport:+'

Call methods on DesktopSupport.getSupport():

DesktopSupport.getSupport().disableSuddenTermination();
DesktopSupport.getSupport().setAboutHandler(e -> {
    // handle About event
});

The API is meant to mostly match the ones it wraps, but it is not quite a drop-in replacement:

• Event objects that have no methods or payloads (e.g. AboutEvent) are just EventObject
• FullScreenUtilities (Apple) and Taskbar/GraphicsEnvironment/etc. (Java 9) methods are on IDesktopSupport with everything else rather than in a separate class
