-- Put a button on the screen. If hit, show a message.
if suit.Button("Hello, World!", 100,100, 300,30).hit then
show_message = true
end
-- if the button was pressed at least one time, but a label below
if show_message then

Example code
------------
The following code will create this UI:
.. image:: _static/demo.gif
::
local suit = require 'suit'
-- generate some assets (below)
function love.load()
snd = generateClickySound()
normal, hovered, active, mask = generateImageButton()
smallerFont = love.graphics.newFont(10)
end
-- data for a slider, an input box and a checkbox
local slider= {value = 0.5, min = -2, max = 2}
local input = {text = "Hello"}
local chk = {text = "Check?"}
-- all the UI is defined in love.update or functions that are called from here
function love.update(dt)
-- put the layout origin at position (100,100)
-- cells will grown down and to the right from this point
-- also set cell padding to 20 pixels to the right and to the bottom
suit.layout:reset(100,100, 20,20)
-- put a button at the layout origin
-- the cell of the button has a size of 200 by 30 pixels
state = suit.Button("Click?", suit.layout:row(200,30))
-- if the button was entered, play a sound
if state.entered then love.audio.play(snd) end
-- if the button was pressed, take damage
if state.hit then print("Ouch!") end
-- put an input box below the button
-- the cell of the input box has the same size as the cell above
-- if the input cell is submitted, print the text
if suit.Input(input, suit.layout:row()).submitted then
print(input.text)
end
-- put a button below the input box
-- the width of the cell will be the same as above, the height will be 40 px
if suit.Button("Hover?", suit.layout:row(nil,40)).hovered then
-- if the button is hovered, show two other buttons
-- this will shift all other ui elements down
-- put a button below the previous button
-- the cell height will be 30 px
-- the label of the button will be aligned top left
suit.Button("You can see", {align='left', valign='top'}, suit.layout:row(nil,30))
-- put a button below the previous button
-- the cell size will be the same as the one above
-- the label will be aligned bottom right
suit.Button("...but you can't touch!", {align='right', valign='bottom'},
suit.layout:row())
end
-- put a checkbox below the button
-- the size will be the same as above
-- (NOTE: height depends on whether "Hover?" is hovered)
-- the label "Check?" will be aligned right
suit.Checkbox(chk, {align='right'}, suit.layout:row())
-- put a nested layout
-- the size of the cell will be as big as the cell above or as big as the
-- nested content, whichever is bigger
suit.layout:push(suit.layout:row())
-- change cell padding to 3 pixels in either direction
suit.layout:padding(3)
-- put a slider in the cell
-- the inner cell will be 160 px wide and 20 px high
suit.Slider(slider, suit.layout:col(160, 20))
-- put a label that shows the slider value to the right of the slider
-- the width of the label will be 40 px
suit.Label(("%.02f"):format(slider.value), suit.layout:col(40))
-- close the nested layout
suit.layout:pop()
-- put an image button below the nested cell
-- the size of the cell will be 200 by 100 px,
-- but the image may be bigger or smaller
-- the button shows the image `normal' when the button is inactive
-- the button shows the image `hovered` if the mouse is over an opaque pixel
-- of the ImageData `mask`
-- the button shows the image `active` if the mouse is above an opaque pixel
-- of the ImageData `mask` and the mouse button is pressed
-- if `mask` is omitted, the alpha-test will be swapped for a test whether
-- the mouse is in the area occupied by the widget
suit.ImageButton(normal, {mask = mask, hovered = hovered, active = active}, suit.layout:row(200,50))
-- if the checkbox is checked, display a precomputed layout
if chk.checked then
-- the precomputed layout will be 3 rows below each other
-- the origin of the layout will be at (400,100)
-- the minimal height of the layout will be 300 px
rows = suit.layout:rows{pos = {400,100}, min_height = 300,
{200, 30}, -- the first cell will measure 200 by 30 px
{30, 'fill'}, -- the second cell will be 30 px wide and fill the
-- remaining vertical space between the other cells
{200, 30}, -- the third cell will be 200 by 30 px

-- the first cell will contain a witty label
-- the label will be aligned left
-- the font of the label will be smaller than the usual font

suit.Label(slider.value, {align='left'}, rows.cell(3))
-- the second cell will show a slider
-- the slider will operate on the same data as the first slider
-- the slider will be vertical instead of horizontal
-- the id of the slider will be 'slider two'. this is necessary, because
-- the two sliders should not both react to UI events
