Rat Widgets

This crate tries to provide an extended set of widgets with

• Event handling
• Focus handling
• Builtin scrolling
• Speed

Event handling

Uses the trait defined in rat-event to implement event-handling for crossterm. All widgets are designed with other event-handlers in mind.

Focus handling

Uses FocusFlag defined by rat-focus internally, to mark the focused widget. This is just a passive flag, that probably can be used with other focus systems. Or you use rat-focus.

Scrolling

Where it makes sense the widgets implement internal scrolling. They use Scroll from rat-scrolled.

Speed

Rendering all the widgets tries hard not to need allocations and extensive copying during rendering.

Special mentions:

• rat-ftable::Table: It uses an adapter for the data for rendering instead of creating Row/Cell structs.

Widgets

All the widgets are plain ratatui widgets, and implement StatefulWidget and the (experimental) StatefulWidgetRef traits.

Event handling uses rat-event::HandleEvent. Currently, crossterm events are implemented.

Layout

There are some layout calculators beyond ratatui's Layout.

Relocation

Widgets like View and Clipper move the widget-image after rendering. This breaks any areas stored in the widget-states.
