I'm not sure the library you're using but this like the one:
https://github.com/Dav1dde/glwtf/blob/master/glwtf/input.d#L163

This code says that the function is protected.

https://github.com/Dav1dde/glwtf/blob/master/glwtf/signals.d#L254

This line is probably mixing in a call to that function into a 
struct

https://github.com/Dav1dde/glwtf/blob/master/glwtf/signals.d#L229

But that struct doesn't inherit from the class so it can't access 
protected fields.
