Awesome Application Framework (libAAF)

-- Load app framework API
os.loadAPI("/libAAF")

-- Create application instance
local app=libAAF.Application.new()

-- Create window
local win=libAAF.Screen.new()

-- Make our application know which window to use
app.appWindow=win

-- Main application code function
AppMain = function()
-- Create new label
local labelHello = libAAF.Label.new()

-- Set label's text
labelHello.text="Hello from Application!"

-- Attach label to window
win:add(labelHello)

-- Then, we'll create a simple button
local buttonExit = libAAF.Button.new()

-- Set its text
buttonExit.text="Exit"

-- Set its position, so it won't overlap our label
buttonExit.x=3
buttonExit.y=3

-- Add click listener to it, so when we click it, application will close
buttonExit.onMouseClick=function(self)
app:dispose()
end

-- And finally, attach button to our window
win:add(buttonExit)
end

-- Start application
app:start(AppMain)

-- Load API
os.loadAPI("/libAAF")

-- Create application instance
local app=libAAF.Application.new()

-- So, we won't add screen to app, it'll only run this code
AppMain=function()
print("Hello from Application!")
end

-- Start our app
app:start(AppMain)
