window key-callback should be mutable #3

Open fecundf opened 3 years ago

fecundf commented 3 years ago

The test code fails with the error "Cannot assign to a readonly variable or a value" until I comment out $window.key-callback = &key-callback

Perhaps key-callback needs to be marked as read-write?

YellowApple commented 3 years ago

Weird; it's already marked with is rw, so I'd expect that to work (and at one point it was indeed working). Does GLFW::set-window-key-callback($window, &key-callback); work?

GLFW::set-window-key-callback gives Could not find symbol '&set-window-key-callback' in 'GLFW'

The META6.json looks like the same as in the repo, GLFW 0.1.0, source-url git://github.com/YellowApple/p6-GLFW.git

This call doesn't crash GLFW::Window::set-key-callback($window, &key-callback); - I still am figuring out which key is 256!

I see method key-callback() is rw in GLFW::Window source code, not sure why it complains.
