QUICKIE

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

Example

local gui = require "Quickie"

-- lazy font loading
local fonts = setmetatable({}, {__index = function(t,k)
    local f = love.graphics.newFont(k)
    rawset(t, k, f)
    return f
end })

function love.load()
    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   = {checked = false, label = "Checkbox"}
local check2   = {checked = false, label = "Another one"}
local input    = {text = ""}
local slider   = {value = .5}
local slider2d = {value = {.5,.5}}
function love.update(dt)
    gui.group.push{grow = "down", pos = {5,5}}
    if gui.Button{text = "Menu"} then
        menu_open.main = not menu_open.main
    end

    if menu_open.main then
        gui.group.push{grow = "right"}
        if gui.Button{text = "Group stacking"} then
            menu_open.right = not menu_open.right
        end

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

                menu_open.foo = not menu_open.foo
            end
            if menu_open.foo then
                gui.Button{text = "???"}
            end

        gui.group.push{grow = "down", pos = {200, 80}}

        love.graphics.setFont(fonts[20])

        gui.group.push{grow = "right"}
        gui.Button{text = "Button"}
        gui.Button{text = "Tight Button", size = {"tight"}}
