# Emigui
|
|
(Experimental, Modularized Immediate mode Graphical User Interface)
|
|
|
|
An immediate mode GUI library written in Rust. For web apps or native apps.
|
|
|
|
## Goals:
|
|
* Lightweight
|
|
* Short, conveniant syntax
|
|
* Responsive (60 Hz without breaking a sweat)
|
|
* Portable
|
|
* Platform independent (the same code works on the web and as a native app)
|
|
|
|
## How it works:
|
|
Loop:
|
|
* Gather input: mouse, touches, screen size, ...
|
|
* Run application code (Immediate Mode GUI)
|
|
* Output is a triangle mesh
|
|
* Render with e.g. OpenGL
|
|
|
|
## Available backends:
|
|
Wherever you can render textured triangles you can use Emigui.
|
|
|
|
Currently two backends have been tested:
|
|
* WebAssembly (emigui_wasm) for making a web app
|
|
* [Glium](https://github.com/glium/glium) for native apps (see example_glium).
|
|
* [miniquad](https://github.com/not-fl3/emigui-miniquad) [web demo](https://not-fl3.github.io/miniquad-samples/emigui.html) [demo source](https://github.com/not-fl3/good-web-game/blob/master/examples/emigui.rs)
|
|
|
|
The same application code can thus be compiled to either into a native app or a web app.
|
|
|
|

|
|
## State
|
|
Mostly a tech demo at this point. I hope to find time to work more on this in the future.
|
|
|
|
Features:
|
|
|
|
* Labels
|
|
* Buttons, checkboxes, radio buttons and sliders
|
|
* Horizontal or vertical layout
|
|
* Column layout
|
|
* Collapsible headers (sections)
|
|
* Windows
|
|
* Resizable regions
|
|
* Vertical scolling
|
|
* Simple text input
|
|
* Anti-aliased rendering of circles, rounded rectangles and lines.
|
|
|
|
## Conventions
|
|
* All coordinates are screen space coordinates, in locial "points" (which may consist of many physical pixels).
|
|
* All colors have premultiplied alpha
|
|
|
|
## Inspiration
|
|
The one and only [Dear ImGui](https://github.com/ocornut/imgui) is a great Immediate Mode GUI for C++ which works with many backends. That library revolutionized how I think about GUI code from something I hated to do to something I now like to do.
