How to use widgets?

[Deicon]

Hello.
I'm trying to understand how widgets work, someone could give a didactic explanation. An explanation of when to use AddClassPostConstruct (); Class (Widget, function (self, ...)).
For example, if I want to remove that inventory bar, image below, and add another image, what should I do?

Thanks in advance.

For the example above, I solved it with the code below. But I still want an explanation of how the widgets work, if anyone can do this favor, I appreciate it.

AddClassPostConstruct("widgets/inventorybar", function(self, owner)   
	self.bgcover:Kill() 
	self.bg:Kill()
	repeat
		table.remove(self.equipslotinfo)
	until #self.equipslotinfo==0
	function Inv:SelectDefaultSlot()
	end
end)

Widgets are UI elements. AddClassPostConstruct is called whenever the specified widget type is made. Beyond that, there isn't really anything super special. The Class function is just used for making a class.
