DGS provides not only POP ( Procedure Oriented Programming ) but also OOP ( Object Oriented Programming ). This page introduces OOP of dgs.

Structure

When using DGS OOP, DGS objects to be operated are no longer elements, instead, they will be tables ( table is the only type whose call methods can be defined in lua ) . Here is the structure of DGS OOP Object: 

DGSObject = {
	DGSElement = DGSElement -- The actual dgs element
	function1,
	function2,
	...
}
  • The built-in functions are non-modifiable
  • Any variable of the table are get/set via dgsSetProperty/dgsGetProperty ( Exclude DGSElement )
  • After importing DGS OOP Class, there is a table called : DGSClass

Get Started

Instead of using 

 label = exports.dgs:dgsCreateLabel(0, 0, 0.5, 0.1, "text", true)

 DGS = exports.dgs
 label = DGS:dgsCreateLabel(0,0,0.5,0.1,"text",true)

 loadstring(exports.dgs:dgsImportFunction())()-- load functions
 label = dgsCreateLabel(0,0,0.5,0.1,"text",true) --create a label

We provides Object Oriented Programming 

 loadstring(exports.dgs:dgsImportOOPClass())()-- load OOP class
 window = dgsWindow(0,0,0.5,0.1,"test",true) --create a window with oop
 label = window:dgsLabel(0,0,1,1,"label",true) --create a label inside the window
 label.text = "DGS OOP Test" --set text

Notice: When you are going to create a child element, there is no need to pass parent as an argument into the function, because the parent dgs element is the function caller.

This is the Wrong Usage:
 loadstring(exports.dgs:dgsImportOOPClass())()-- load OOP class
 window = dgsWindow(0,0,0.5,0.1,"test",true) --create a window with oop
 label = dgsLabel(0,0,1,1,"label",true,window) --create a label inside the window ( Wrong )
 label.text = "DGS OOP Test" --set text
This is the Correct Usage:
 loadstring(exports.dgs:dgsImportOOPClass())()-- load OOP class
 window = dgsWindow(0,0,0.5,0.1,"test",true) --create a window with oop
 label = window:dgsLabel(0,0,1,1,"label",true) --create a label inside the window ( Correct )
 label.text = "DGS OOP Test" --set text

Special

For Position and Size, we have a more convenient method to do. 

 loadstring(exports.dgs:dgsImportOOPClass())()-- load OOP class
 window = dgsWindow(0,0,0.5,0.1,"test",true) --create a window with oop
 window.position.x = 0.2 -- For relative position
 window.position.relative = false -- Change to absolute position
 window.position.x = 10 -- For absolute position
 window.size.relative = false
 window.size.w = 400
