# QUICKIE

Quickie is an [immediate mode gui][IMGUI] library for [LÖVE][LOVE]. Initial inspiration came from the article [Sol on Immediate Mode GUIs (IMGUI)][Sol]. You should check it out to understand how Quickie works.


# Example

	local gui = require "Quickie"

	function love.load()
		-- preload fonts
		fonts = {
			[12] = love.graphics.newFont(12),
			[20] = love.graphics.newFont(20),
		}
		love.graphics.setBackgroundColor(17,17,17)
		love.graphics.setFont(fonts[12])

		-- group defaults
		gui.group.default.size[1] = 150
		gui.group.default.size[2] = 25
		gui.group.default.spacing = 5
	end

	local menu_open = {
		main  = false,
		right = false,
		foo   = false,
		demo  = false
	}
	local check1   = false
	local check2   = false
	local input    = {text = ""}
	local slider   = {value = .5}
	local slider2d = {value = {.5,.5}}

	function love.update(dt)
		gui.group.push{grow = "down", pos = {5,5}}

		-- all widgets return true if they are clicked on/activated
		if gui.Checkbox{checked = menu_open.main, text = "Show Menu"} then
			menu_open.main = not menu_open.main
		end

		if menu_open.main then
			gui.group.push{grow = "right"}

			-- widgets can have custom ID's for tooltips etc (see below)
			if gui.Button{id = "group stacking", text = "Group stacking"} then
				menu_open.right = not menu_open.right
			end

			if menu_open.right then
				gui.group.push{grow = "up"}
				if gui.Button{text = "Foo"} then
					menu_open.foo = not menu_open.foo
				end
				if menu_open.foo then
					gui.Button{text = "???"}
				end
				gui.group.pop{}

				gui.Button{text = "Bar"}
				gui.Button{text = "Baz"}
			end
			gui.group.pop{}

			if gui.Button{text = "Widget demo"} then
				menu_open.demo = not menu_open.open
			end

		end
		gui.group.pop{}

		if menu_open.demo then
			gui.group{grow = "down", pos = {200, 80}, function()
				love.graphics.setFont(fonts[20])
				gui.Label{text = "Widgets"}
				love.graphics.setFont(fonts[12])
				gui.group{grow = "right", function()
					gui.Button{text = "Button"}
					gui.Button{text = "Tight Button", size = {"tight"}}
					gui.Button{text = "Tight² Button", size = {"tight", "tight"}}
				end}

				gui.group{grow = "right", function()
					gui.Button{text = "", size = {2}} -- acts as separator
					gui.Label{text = "Tight Label", size = {"tight"}}
					gui.Button{text = "", size = {2}}
					gui.Label{text = "Center Label", align = "center"}
					gui.Button{text = "", size = {2}}
					gui.Label{text = "Another Label"}
					gui.Button{text = "", size = {2}}
				end}

				gui.group.push{grow = "right"}
				if gui.Checkbox{checked = check1, text = "Checkbox", size = {"tight"}} then
					check1 = not check1
					print(check1)
				end
				if gui.Checkbox{checked = check2, text = "Another Checkbox"} then
					check2 = not check2
				end
				if gui.Checkbox{checked = check2, text = "Linked Checkbox"} then
					check2 = not check2
				end
				gui.group.pop{}

				gui.group{grow = "right", function()
					gui.Label{text = "Input", size = {70}}
					gui.Input{info = input, size = {300}}
				end}

				gui.group{grow = "right", function()
					gui.Label{text = "Slider", size = {70}}
					gui.Slider{info = slider}
					gui.Label{text = ("Value: %.2f"):format(slider.value), size = {70}}
				end}

				gui.Label{text = "2D Slider", pos = {nil,10}}
				gui.Slider2D{info = slider2d, size = {250, 250}}
				gui.Label{text = ("Value: %.2f, %.2f"):format(slider2d.value[1], slider2d.value[2])}
			end}
		end

		-- tooltip (see above)
		if gui.mouse.isHot('group stacking') then
			local mx,my = love.mouse.getPosition()
			gui.Label{text = 'Demonstrates group stacking', pos = {mx+10,my-20}}
		end
	end

	function love.draw()
		gui.core.draw()
	end

	function love.keypressed(key, code)
		gui.keyboard.pressed(key)
		-- LÖVE 0.8: see if this code can be converted in a character
		if pcall(string.char, code) code > 0 then
			gui.keyboard.textinput(string.char(code))
		end
	end

	-- LÖVE 0.9
	function love.textinput(str)
		gui.keyboard.textinput(str)
	end
