About
Simplified JNA is a library that allows for the quick creation of mouse and keyboard hooks in a multithreaded environment. Additionally it provides easy to use methods for sending inputs to window, mouse, and keyboard objects.
Usage
You can import this with maven via JitPack:
Add the repo to your pom:
<repositories>
<repository>
<id>jitpack.io</id>
<url>https://jitpack.io</url>
</repository>
</repositories>
And add the dependency:
<dependency>
<groupId>com.github.Col-E</groupId>
<artifactId>Simplified-JNA</artifactId>
<version>1.0</version>
</dependency>
Examples
In these samples, returing false allows the event to be parsed by the system. Chaning the return value to true will cancel the event.
Keyboard Hook
KeyEventReceiver keyHook = new KeyEventReceiver() {
@Override
public boolean onKeyUpdate(SystemState sysState, PressState pressState, int time, int vkCode) {
System.out.println("Is pressed:" + (pressState == PressState.DOWN));
System.out.println("Alt down:" + (sysState == SystemState.SYSTEM));
System.out.println("Timestamp:" + time);
System.out.println("KeyCode:" + vkCode);
return false;
}
};
KeyHook.hook(keyHook);Mouse Hook
MouseEventReceiver mer = new MouseEventReceiver() {
@Override
public boolean boolean onMousePress(MouseButtonType type, HWND hwnd, POINT info) {
boolean isLeft = type == MouseButtonType.LEFT_DOWN;
if (isLeft) {
System.out.println("Left mouse button has been pressed!")
}
return false;
}
@Override public boolean onMouseRelease(MouseButtonType type, HWND hwnd, POINT info) { return false; }
@Override public boolean onMouseScroll(boolean down, HWND hwnd, POINT info) { return false; }
@Override public boolean boolean onMouseMove(HWND hwnd, POINT info) { return false; }
};
MouseHook.hook(mer);
