Emigui

(Experimental, Modularized Immediate mode Graphical User Interface)

An immediate mode GUI library written in Rust. Compiles to WASM.

Goals:

• Easy to use
• Platform independent (the same code should run on web and native)
• Responsive

How it works:

Loop:

• Gather input: mouse, touches, screen size, ...
• Run application code (Immediate Mode GUI)
• Output is a triangle mesh
• Render with WebGL

State

Mostly a tech demo at this point. I hope to find time to work more on this in the future.

Features:

• Text
• Buttons, checkboxes, radio buttons and sliders
• Horizontal or vertical layout
• Column layout
• Collapsible headers (sections)
• Anti-aliased rendering of circles, rounded rectangles and lines.

Roadmap:

• Native backend
• Some examples / documentation
• Text input

Inspiration

Dear ImGui is a great Immediate Mode GUI for C++ which works with many backends.
