A Widget
is a unit that is displayed on the screen. It is associated
with a mutable state s
. It provides an event handler with default
keybindings and can generate a renderable Image
.
Widget modules should provide a Widget
instance and additionally a
collection of actions that can be invoked by external event handlers:
widgetAction ::VgrepT
s mRedraw
