Example

require "ImGui"

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

local window01 = true -- the starting state of window01 (collapsed, expanded), with a close button
local window02 = true -- the starting state of window02 (collapsed, expanded), without a close button
local window03 = true -- the starting state of window03 (collapsed, expanded), with no title bar

function onEnterFrame(e)
	-- 1 we start ImGui
	imgui:newFrame(e)

	-- 2 we add a child window and build our GUI
	if window01 then -- if window exists
		local windowdrawn = false
		window01, windowdrawn = imgui:beginWindow( -- with close button
			"Hello ImGui v"..ImGui._VERSION, -- window title
			window01 -- is window expanded
		)
		if windowdrawn then -- the variable is false when main window is collapsed
			imgui:text("This is an ImGui text.") -- we add a text element to our GUI
			imgui:textColored("This is a colored text.", 0xff00ff, 1)
			-- ...
		end
		imgui:endWindow()
	end

	window02 = imgui:beginWindow("Window02") -- without close button
	if window02 then
		imgui:text("I am a text in window02")
		print(e.deltaTime) -- test
		-- ...
	end

	if window03 then -- if window exists
		local windowdrawn = false
		window03, windowdrawn = imgui:beginWindow(
			0,
			nil,
			ImGui.WindowFlags_NoTitleBar
		)
		if windowdrawn then -- the variable is false when window is collapsed
			imgui:text("This is an ImGui text.") -- we add a text element to our GUI
			imgui:textColored("This is a colored text.", 0xff00ff, 1)
			-- ...
		end
		imgui:endWindow()
	end

	-- 3 we end the frame and render to screen
	imgui:endFrame()
	imgui:render()
end

stage:addEventListener(Event.ENTER_FRAME, onEnterFrame)
