function MyClass:onEnterFrame(e)
	-- 1 we start ImGui
	self.imgui:newFrame(e.deltaTime)
	-- 2 we build our GUI
	if self.window01 then -- is window01 existant?
		local windowdrawn = false -- is window01 colapsed?
		local ischanged = false
		self.window01, windowdrawn = self.imgui:beginWindow(
			"Hello ImGui", -- window title
			self.window01 -- is window01 existant?
		)
		if windowdrawn then -- the variable is false when window01 is collapsed
			self.isbold, ischanged = self.imgui:checkbox("Bold", self.isbold)
