kiUi Build Status Coverity Scan Build Status

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.

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");

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

Skins

kiUi was conceived so that each element can be styled in a way very similar to CSS

Editor

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