How to refer GL context in AWT Mouse Event

We can't do that because we're not responsible for AWT which is part of the Java API, not a JogAmp API. Your problem lies in AWT itself. Which version of Java do you use? By the way, the current API already allows to get and set the surface scale. The things are better when using NEWT as it is designed with HiDPI in mind, the documentation is clear.

I apologize for my slow answer.
I didn't notice existence of the next page, now i found your message.
It's most that you say.
Thank you very much for your valuable time.

Best Regards,
