I have read about using native Window handles in Java. I have downloaded the JNA 4.1.0 JAR file and added to the Eclipse Java Build Path.
However, when I type User32
and press Ctrl+Space, Eclipse doesn't give suggestions for an import.
What I have tried: I have created my own User32 class like in this answer.
However, I doubt that this is the correct way of doing it. Maybe I'm too optimistic, but I expect it to be easier... :-)
As pointed out in the comments, I forgot to add jna-platform.jar
to the Java Build Path.
