CrystGLFW::Event::WindowScroll

A CrystGLFW::Event::WindowScroll is generated when the user scrolls while a Window has input focus. It is yielded to the block defined by on_scroll.

window = Window.new

window.on_scroll do |event|
  puts "scroll offset: #{event.offset}"
end

window

You can retrieve the event's associated Window using the window method:

event.window # => CrystGLFW::Window

offset

You can retrieve the scroll offset using the offset method:

event.offset # => {x: Float64, y: Float64}
