A Handler.t
handles a keyboard event by returning a Vdom.Event.t
. These should
be used as building blocks for keyboard event handlers, for instance to handle a
specific set of keys.
with_prevent_default t
handles the event using handler t
, and additionally
prevents the default handler.
val only_handle_if : ?prevent_default:unit ‑> Condition.t ‑> t ‑> t
only_handle_if ?prevent_default cond t
handles the event using handler t
if
cond ev
evaluates to true (and additionally prevent the default handler if
prevent_default
is passed in), and does nothing otherwise.
val handle_by_case : ?prevent_default:unit ‑> (Condition.t * t) list ‑> t
handle_by_case
is similar to only_handle_if
, but allows the user to provide a
list of handlers and their respective conditions instead of a single one. If
multiple handlers' conditions evaluate to true, the first one is used.
