C# Realtime GUI System


Squid is a user interface framework designed for creating interfaces for games and other 2D/3D realtime applications. It operates using a Retained Mode system and can be used with any rendering engine on platforms that support the .NET 2.0 framework. Squid is a UI blackbox that is easy to integrate and is engine agnostic. It does not manage actual texture or font resources, only integers and strings, and requires the implementation of a single interface called ISquidRenderer.


  • Scale9 Texture Grid: Allows for smooth scaling and resizing of textures.
  • Docking and Anchoring: Enables precise control of the positioning and alignment of UI elements.
  • Margin and Padding: Provides options for creating space around UI elements.
  • Z-Order, Clipping, and Scissoring: Allows for control over element stacking, clipping of content, and scissoring of UI elements.
  • Hierarchical Opacity: Allows for setting opacity for individual UI elements and their children.
  • Input Event Handlers: Supports capturing and handling various input events.
  • International Keyboard Support: Includes support for keyboard input in different languages.
  • Custom Mouse Cursors: Allows for the customization of mouse cursors.
  • Tooltips: Supports the display of tooltips for UI elements.
  • Drag & Drop: Provides functionality for dragging and dropping UI elements.
  • Snapping Windows: Enables the snapping of windows to certain positions or grids.
  • Modal Windows: Supports the creation of modal windows.
  • Control State Fading: Allows for fading in and out of UI elements based on their state.
  • Easy Skinning via Styles: Provides a convenient way to apply customized styles to UI elements.
  • Automatic Batching: Optimizes rendering performance by automatically batching draw calls.
  • Easy to Extend: Allows for easy extension and customization of the framework.
  • Fast: Designed for optimal performance.

UI Kits & Components

A UI kit provides developers with a set of reusable components that can be easily integrated into a website or application. These components are pre-designed with consistent styling and functionality, allowing developers to save time and effort in the design and development process. UI kits can be either custom-built or third-party, and often include components for buttons, forms, typography, icons, and more.
