Crate kas_view

Expand description

View widgets and shared data

View widgets allow data-oriented design. This is vaguely similar to the Model-View-Controller pattern or Elm’s Model-View-Update design, but with no direct link between Model and Controller:

Model traits describe data models: ListData, MatrixData
Drivers describe how to build a widget view over data and (optionally) how to handle messages from view widgets
Controllers are special widgets which manage views over data

Three controllers are provided by this crate:

ListView constructs a row or column of views over indexable data
MatrixView constructs a table/sheet of views over two-dimensional indexable data

Both ListView and MatrixView support virtual scrolling: the number of view widget instances is limited (approximately) to the number required to cover the visible area, and these are re-used to enable fast scrolling through large data sets.
