Fire mouse event when XTestFakeButtonEvent called

[ghost]

Background

Sikuli is an automation framework that relies on Java's Robot class to simulate mouse events. KmCaster is a Java desktop application based on JNativeHook that shows keyboard and mouse events on-screen.

Problem

The simulated mouse events from Sikuli do not trigger in KmCaster, although keyboard events do.

Technical

The OpenJDK's Robot class relies on a RobotPeer implementation, which calls XTestFakeButtonEvent. It appears that libuiohook's post_event.c calls XTestFakeButtonEvent to send mouse presses to X11, but doesn't seem to offer a hook to listen for mouse presses from X11 sent via XTestFakeButtonEvent.

Feature Request

Although an infinite loop could loom without due care should both sending to and listening for XTestFakeButtonEvent calls be enabled, having a way to percolate simulated X11 mouse events to applications would be useful when interacting with automation frameworks (Selenium may have the same issues as Sikuli).
