Brisk

Brisk is a modern, cross-platform C++ GUI framework designed to build responsive, high-performance applications with flexibility and ease.

Initially developed for a graphics-intensive proprietary project with a complex and dynamic GUI.

[!Note] The Brisk library is currently under active development. Breaking changes may occur, and the documentation might not always be up to date. Contributions are always welcome!

Key Features

• Declarative GUI: Enables the creation of complex GUIs in C++ using a flexible declarative syntax.
• Stateful & Stateless Widgets: Supports both modes, with powerful binding for efficient state management.
• Stylesheets: Offers declarative styles to easily modify the application's look and feel.
• Hardware-Accelerated Graphics: Backends include D3D11, D3D12, Vulkan, OpenGL, Metal, and WebGPU.
• Color Processing: Supports various color spaces and linear color blending for physically accurate rendering.
• Font support: OpenType support, advanced shaping for non-European languages, ligatures, rich text formatting, SVG fonts, emojis, and rendering for RTL and bidirectional text.
• Modular Architecture: Core, Graphics, Window, GUI, Network, and Widgets modules for versatile application development.

Modules

Core

• Compression & Basic Cryptography: Provides data compression and basic cryptographic functions, including hashing algorithms.
• Dynamic Library Loading: Loads and interacts with .dll or .so files dynamically.
• String Manipulation: Handles UTF-8, UTF-16, and UTF-32, with text manipulation utilities.
• Stream I/O: Input/output operations for handling data streams.
• Localization Support: Basic localization and internationalization features for multilingual applications.
• Logging: Built-in logging framework for application diagnostics.
• Reflection: Supports reflection.
• Serialization: Serializes/deserializes data to/from JSON.
• App-Global Settings: Manages global application settings.
• Threading: Provides task queues for multi-threaded applications.
• Binding: Supports value binding, capable of handling multi-threaded environments.

Graphics

• Color & Colorspaces: Supports working with colors, including various colorspaces.
• Geometry: Provides 2D geometry types like Rect, Point, Size, and 2D matrices for transformations.
• Canvas & Path: Supports drawing with paths and Bézier curves.
• SVG Rasterization: Renders SVG images into raster formats.
• Image Processing: Supports image encoding, decoding, resizing, and manipulation.
• Font Handling: Manages fonts, including loading, rendering, caching, and text layout. Supports advanced text shaping (using HarfBuzz) and SVG fonts (emojis).

Window

• Clipboard: Provides clipboard access for copy/paste functionality.
• OS Dialogs: Native dialogs for file open/save, folder selection, and message boxes.
• Display Information: Retrieves and manages display/monitor information from the OS.
• Buffered rendering : Brisk supports both buffered rendering, which enables partial repaints, and direct rendering to the window backbuffer.

GUI

• Widgets: Includes a wide variety of widgets with CSS-style flex layout.
• Style Sheets: Styles your widgets using a stylesheet system that supports property inheritance. Viewport-relative units are supported (vh, vw, vmin, `vmax)
• Binding Support: Data-binding between UI elements and application data. Supports transforming values using a function on-the-fly and compound values (e.g., sums of other values).
• Stateful and Stateless Modes: Choose between stateful widgets for persistent state or stateless widgets for easily rebuilding widget subtrees.
• Drag-and-Drop: Supports drag-and-drop within the GUI, with the option to attach a C++ object to represent the dragged data.

Widgets

• Widgets: Includes buttons, lists, comboboxes, toggle switches, radio buttons, progress bars, sliders, scroll boxes, checkboxes, popup buttons, tabs, tables, spin boxes, dialogs, and more. All public properties are styleable and bindable.
• Layouts: Supports CSS flexbox-style layouts.
• Text Editors: Provides text editing widgets with LTR and RTL text support.
• WebGPU: Ability to render 3D content to the window using the WebGPU API (backed by Google's Dawn), with full support for composition with the UI.

Requirements ⚙️

• C++20 Compiler: Brisk requires a C++20-compatible compiler such as MSVC 2022, Clang, XCode, or GCC.
• Dependency Management: Uses vcpkg to manage dependencies across platforms, simplifying the build process. Alternatively, you can download prebuilt binaries.
