Auto-layout Ui library, lightweight, skinnable and system agnostic, with an OpenGL backend

kiUi

kiUi is a lightweight auto-layout Ui library, abstracted out from any rendering or input code.

kiui supports Emscripten : try the live demo here.

It is designed according to the following design goals :

• Separation of Ui appearance and logic
• Automatic layout as the norm, not the exception (as in HTML)
• Easy styling, separated from logic (as in CSS)
• Brevity and simplicity above everything else, especially in C++ code
• Good for both an editor Ui and a game Ui

Auto-Layout

Every single element in kiUi auto-layouts ! You have nothing to do. No position to set, no size to determine.

• Code the logic : Just add your widgets and define the logic as you please.
• Code the appearance : Just set your fonts, font-size, images, and kiUi will do the rest.

The style can be defined and tweaked separately by an artist. Style are defined in C++ as of now, but Style Sheets are planned to come soon.

Skins

kiUi was conceived so that each element can be styled in a way very similar to CSS, through Style Sheets You can switch between Styles Sheets on the fly

Usage

RootSheet& root = uiwindow.rootSheet();
Window& window = root.emplace<Window>("Example window");

Expandbox& expandbox = window.emplace<Expandbox>("Collapsable box");

Label& label = expandbox.emplace<Label>("kiUi says hello.");
Button& button = expand.emplace<Button>("Push me");

For a more in-depth usage example look at the full demo implementation : Example

Nano

kiUi comes with a light renderer / input system based on NanoVG and GLFW to quickly bootstrap a prototype application in a few lines of code.

GlWindow glwindow(1200, 800, "mk UiEditApp");
glwindow.initContext();

UiWindow& uiwindow = glwindow.uiWindow();
bool pursue = true;
while(pursue)
    pursue = glwindow.renderFrame();

Widgets

• Dockspace
• Tabber
• Table
• Window (resize, drag, dock)
• Radiobutton
• Dropdown

Editor

kiUi will come with a simple editor which also uses kiUi for its interface
