About

JNativeHook is a library to provide global keyboard and mouse listeners for Java. This will allow you to listen for global shortcuts or mouse motion that would otherwise be impossible using pure Java. To accomplish this task, JNativeHook leverages platform-dependent native code through Java's native interface to create low-level system-wide hooks and deliver those events to your application.

The following events are available via their respective listeners.

• Key Press Events
• Key Release Events
• Key Typed Events
• Mouse Down Events
• Mouse Up Events
• Mouse Click Events
• Mouse Move Events
• Mouse Drag Events
• Mouse Wheel Events

In addition to global event listeners, this library has the ability to post native events back to the native operating system.
