Class: ImGui

Description

Displays 2 float drag sliders, side by side. 

(number), (number), (bool) =
  ImGui:dragFloat2(label, value1, value2, [incStep=1, min=0, max=0, formatString="%.3f", ImGuiSliderFlags=0])

Parameters

label: (string) the label
value1: (number) the current 1st value
value2: (number) the current 2nd value
incStep: (number) the increment step
min: (number) the min value
max: (number) the max value
formatString: (string) the format of the value
ImGuiSliderFlags: (number) the drag slider flag

Return values

Returns (number) the current 1st value
Returns (number) the current 2nd value
Returns (bool) whether one of the current values has changed

Example

require "ImGui"

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

local window01 = true
local dragvalue01 = 0
local dragvalue02 = 30

function onEnterFrame(e)
	-- 1 we start ImGui
	imgui:newFrame(e.deltaTime)
	-- 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!") -- we add a text element to our GUI
		local isChanged = false
		dragvalue01, dragvalue02, isChanged = imgui:dragFloat2("x, y", dragvalue01, dragvalue02, 0.2, 0, 100, "%.3f", 2)
		if isChanged then print(dragvalue01, dragvalue02) end
--		print(e.deltaTime)
	end
	-- 3 we end the frame and render to screen
	imgui:endFrame()
	imgui:render()
end

stage:addEventListener(Event.ENTER_FRAME, onEnterFrame)
