Mouse Wheel Emulator

This project emulates the mouse wheel using mouse movement and keyboard shortcuts (and/or mouse keyboard shortcuts). You can use it for a tablet to emulate mouse wheel with a pen. This works in any application and on different platforms (for this purpose, it uses this library).

Features

• You can use keyboard and mouse keyboard shortcuts together or separately.
• You can configure the mouse movement threshold in pixels to control the scroll sensitivity.
• You can set a scrolling rule that defines which axes are used, which direction is scrolled up or down, or even scrolling from a point as from the center of circle.
• You can use it headless since jnativehook library is AWT independent.

Running

Run it only on the command line cause it doesn't have any interface. Otherwise, you will have to terminate the process through the Task Manager.

java -jar emulator.jar

Java 8 or above is required.

Configuration

You can pass the emulator config path through the arguments:

java -jar emulator.jar [path to config]

The default config is in the .jar archive and looks like below. All fields are optional.

Note: see native keycodes for shortcuts here .
