My current attempt at getting an event of global keypress (eg: user hits a keyboard shortcut, from anywhere in the UI, to trigger opening of modal dialog) is:
prerender_ blank $ do
-- ctx <- askJSM
doc <- currentDocumentUnchecked
win <- currentWindowUnchecked
let clicked = traceEvent "hit" $ keydown Enter win
widgetHold_ (text "Waiting") $
ffor clicked $ \() -> do
text "CLICKED"
However, this fails to typecheck
• Could not deduce: DomEventType JSDOM.Types.Window
'KeydownTag ~ Word arising from a use of ‘keydown’
Looking at the source, only Element EventResult d t has an instance, but not Window or Document.
What is the idiomatic way to achieve what I'm trying to do here, in reflex / ghcjs?
