B4J Tutorial Floating ContextMenu using jNativeHookB4j

This is an example of using @Roycefer 's jNativeHook to monitor all mouse events, even outside of the current app. It uses a ContextMenu to replicate the right click functionality. Default behaviour is overridden by the jNativeHook library and returning false from the relevant event sub.

It uses a dummy form to enable the context menu to be placed anywhere on the screen.

It's not been comprehensively tested and I can't guarantee it will work on Mac or Linux, but would be interested to know if it does.

Get the jNativehook files from here: https://www.b4x.com/android/forum/threads/jnativehookb4j-for-intercepting-system-input-events.55826/

Hope you enjoy it.

It's still the same. I have an idea if CSSutils might solve the problem. CSS styling from code. What do you think about that?

I can't see that it would make any difference where the CSS is set.

Try FCMTest1.zip
