I don't know exactly, because I'm not a GURU of the luna-surfacemanager which is responsible for graphics management in webOS platform. But, I think this topic ([https://www.webosose.org/docs/guides/core-topics/graphics-input/graphics-input-overview/](https://www.webosose.org/docs/guides/core-topics/graphics-input/graphics-input-overview/)) can help you.

Also, you can find the source code on github : [https://github.com/webosose/luna-surfacemanager](https://github.com/webosose/luna-surfacemanager)
