Example

require "ImGui"

local imgui = ImGui.new()
stage:addChild(imgui)

local window01 = true
local value = math.pi/4 -- 45 degrees

function onEnterFrame(e)
	-- 1 we start ImGui
	imgui:newFrame(e)
	-- 2 we add some child windows and build our GUI
	window01 = imgui:beginWindow("Window 01") -- no close button (X)
	if window01 then -- the variable is false when window is collapsed
		imgui:text("Hello Dear ImGui!")
		local isChanged = false
		value, isChanged = imgui:sliderAngle("slider angle", value, -90, 90, "%.2f", 0)
		if isChanged then print(value) end
	end
	-- 3 we end the frame and render to screen
	imgui:endFrame()
	imgui:render()
end

stage:addEventListener(Event.ENTER_FRAME, onEnterFrame)
