AwesomeWM - Blocking mouse scroll bind

focus_different_client.lua

-- Focus different client
-- The input is passed to the client before switching focus *(just like in `unfocus_client.lua)*
client.connect_signal("request::default_mousebindings", function()
	awful.mouse.append_client_mousebindings {
		awful.button({ "Mod4" }, 4, function(c)
			for _, other in ipairs(client.get()) do
				if other ~= c then
					client.focus = other
					break
				end
			end
			gears.timer.delayed_call(function()
				client.focus = c
			end)
		end),
	}
end)

mousegrabber_continuous.lua

-- Mousegrabber that runs for some amount of loops
-- Prevents the client from receiving the input as long as the mouse hasn't moved
-- Unable to determine when to stop grabbing, since `data.buttons[4]` is always `false`
client.connect_signal("request::default_mousebindings", function()
	awful.mouse.append_client_mousebindings {
		awful.button({ "Mod4" }, 4, function(c)
			local count = 5
			mousegrabber.run(function(data)
				print("Scrolled up on " .. c.class)
				count = count - 1
				return count > 0
			end, "arrow")
		end),
	}
end)

mousegrabber_single.lua

-- Mousegrabber that runs only once
-- No discernible difference
client.connect_signal("request::default_mousebindings", function()
	awful.mouse.append_client_mousebindings {
		awful.button({ "Mod4" }, 4, function(c)
			mousegrabber.run(function(data)
				print("Scrolled up on " .. c.class)
				return false
			end, "arrow")
		end),
	}
end)

move_mouse.lua

-- Move the mouse to empty space or space that is occupied by a different client
-- Doesn't work for the initial input
-- After initial input it reliably(?) prevents the client from receiving input
client.connect_signal("request::default_mousebindings", function()
	awful.mouse.append_client_mousebindings {
		awful.button({ "Mod4" }, 4, function(c)
			local previous = mouse.coords()
			mouse.coords { -- Position on screen where [no client] / [client different that `c`] is present
				x = 1930, y = 1110,
			}
			gears.timer.delayed_call(function()
				mouse.coords {
					x = previous.x, y = previous.y,
				}
			end)
			print("Scrolled up on " .. c.class)
		end),
	}
end)

signals.lua

-- Call either `mouse::enter` or `mouse::leave`
-- No discernible difference
client.connect_signal("request::default_mousebindings", function()
	awful.mouse.append_client_mousebindings {
		awful.button({ "Mod4" }, 4, function(c)
			c:emit_signal("mouse::leave")
			client.emit_signal("mouse::leave", c)
			print("Scrolled up on " .. c.class)
		end),
	}
end)

unfocus_client.lua

-- Unfocus the client
-- The input is passed to the client before switching focus
client.connect_signal("request::default_mousebindings", function()
	awful.mouse.append_client_mousebindings {
		awful.button({ "Mod4" }, 4, function(c)
			client.focus = nil
			print("Scrolled up on " .. c.class)
		end),
	}
