OOP Syntax Help! I don't understand this!

Example

This example creates a window, a text label, gets the text extent and font height, and sets the text label size according to these values. 

-- create the window (the container for our label)
local myWindow = guiCreateWindow ( 0, 0, 0.5, 0.4, "Information", true )

-- create the label
local myLabel = guiCreateLabel ( 10, 10, 0, 0, "This is my text container", false, myWindow )
