Getting information about input devices

JavaFX for embedded Linux devices contains a small application for reading input device configuration and the events generated by these devices. This application is included in the JavaFX runtime and is run with:

java com.sun.glass.ui.monocle.GetEvent

GetEvent shows information on all input devices found by JavaFX, including:

Device input nodes
Device properties
Absolute axis ranges
Product IDs
Linux events generated by the devices

In most device configurations GetEvent must be run as root in order to have permissions to identify and track input devices.

Tracing input events while JavaFX is running

JavaFX for embedded devices provides the following system properties to track input events:

Property	Type	Description
`monocle.input.traceEvents`	boolean	Traces input events
`monocle.input.traceEvents.verbose`	boolean	Has the effect of `monocle.input.traceEvents` and also traces low-level events read and processed by JavaFX. This includes the pipeline of filters used for touch event cleanup.
