Crate kas

KAS, the toolKit Abstraction Library

KAS is a GUI library, providing approximately two thirds of GUI toolkit functionality:

• widget model
• widget layout engine
• widget event handling
• widget types

The remaining third is provided by a separate crate, referred to as the "toolkit". A KAS toolkit must provide:

• system interfaces (window creation and event capture)
• widget rendering and sizing
