gogpu/ui

Pure Go GUI Toolkit
Modern widgets, layouts, and styling — built on GoGPU

---

Status: Planned

This project is not yet started. It will be developed after gogpu/gogpu reaches v0.2.0 (basic 2D rendering).

Star the repo to be notified when development begins!

Vision

A modern, GPU-accelerated GUI toolkit for Go that:

• Zero CGO — Pure Go, simple go build
• GPU Rendered — Smooth 60fps UI with hardware acceleration
• Immediate + Retained — Flexible rendering modes
• Cross-Platform — Windows, Linux, macOS
• Themeable — Built-in dark/light themes, custom styling

---

Planned Features

Widgets

• Button, Label, TextInput
• Checkbox, Radio, Slider
• Dropdown, ComboBox
• List, Table, Tree
• Tabs, Accordion
• Modal, Tooltip, Popup
• ScrollView, SplitPane

Layouts

• Flex (row/column)
• Grid
• Stack
• Absolute positioning

Styling

• CSS-like styling
• Themes (dark/light)
• Custom fonts
• Icons (embedded SVG)

Accessibility

• Keyboard navigation
• Screen reader support

Target API

package main

import (
    "github.com/gogpu/gogpu"
    "github.com/gogpu/ui"
)

func main() {
    app := gogpu.NewApp(gogpu.Config{
        Title: "My App",
        Width: 800,
        Height: 600,
    })

    // Create UI
    root := ui.Column(
        ui.Label("Hello, GoGPU!").FontSize(24),
        ui.Row(
            ui.Button("Click Me").OnClick(func() {
                println("Clicked!")
            }),
            ui.Button("Cancel"),
        ).Gap(8),
        ui.TextInput().Placeholder("Enter text..."),
    ).Padding(16).Gap(12)

    app.SetRoot(root)
    app.Run()
}

Note: This API is a design target, not implemented yet.
