A UI framework for Go that lets you build graphical interfaces using a declarative approach. Built on raylib-go.

Goui is a declarative UI framework for Go that provides:

• Component System

  • Built-in components (Text, Button, Rect, Image, Layout)
  • Component composition and nesting
  • Declarative component creation

• Layout & Styling

  • Flexbox-based layout system
  • Responsive layouts with percentage-based sizing
  • Comprehensive styling (colors, padding, margins, borders, shadows)
  • Text rendering with font styling
  • Image support

• Interactive Features

  • Event handling (mouse, keyboard, focus)
  • State management (hover, active, focus, disabled)
  • Component state transitions

The framework is currently in active development. The core features are implemented and working:

• Core rendering engine and application lifecycle
• All basic components and layout system
• Complete styling system
• Event system and state management
• Component composition and responsive layouts

// Create a header component with text and image
header := Rect(
    Text("Welcome to Goui").FontSize(24).Color("white"),
    Image("logo.png").Width(50).Height(50),
).Background("navy").Padding(20).FlexDirection("row").JustifyContent("space-between")

// Create a content section with nested components
content := Rect(
    Rect(
        Text("Left Panel").Color("white"),
        Image("icon1.png").Width(32).Height(32),
    ).Background("green").Padding(20).Width("30%"),
    Rect(
        Text("Main Content").Color("black"),
        Text("A simple example showing text, images, and nested components").FontSize(14),
    ).Background("white").Padding(20).Width("70%"),
).Background("lightgray").Padding(10).FlexDirection("row").Height(300)

// Combine components into the root layout
root := Rect(
    header,
    content,
).Background("black").Padding(20).Width(800).Height(600).FlexDirection("column")

app := core.NewApplication("My App", 800, 600)
app.SetRoot(root)
app.Run()
