Introduction

This is a small overview of how NGUI works internally. The core of NGUI are three modules:

• ngui.nim: Where the Widgets (NElements) and procedures are described.
• ngui_backend_interface.nim: This is a list of functions that serve as the interface between ngui and some guitoolkit. At the moment only GTK3 is supported. ngui.nim will communicate with the backend through internalX functions (for example: internalNewApp, internalGetText, internalAdd ...)
• ngui_backend_util.nim: A set of util functions to make the implementation of backends simpler.

As an example of an implementation, checkout the module src/backends/ngui_begtk3.nim
