Module dom 

The one wasm-bound layer of the input path: a DOM event, as a sample.

Constants

DRAGGED 🔒

The pointer a drag is carried by. A browser runs a file drag itself and raises no pointer events for it, so the motion this reports belongs to no real device and takes an id no device will claim.

LINES_PER_PAGE 🔒

And pages, for the rare host that reports those.

PIXELS_PER_LINE 🔒

WheelEvent.deltaMode counts lines rather than pixels; Firefox reports wheels this way. epaint uses the same nominal row height.

Functions

at 🔒

button_of

Which button a MouseEvent.button names. Public because a host has to know one before the sample is made: a button the camera drives must also be refused whatever the platform binds it to.

dragged

Where a file being dragged over the canvas is, as a motion.

held 🔒

key

The canvas’s own reading of event, or None for a key it does not read — which may still be a Chord; see chord_of.

pixels 🔒

pointer

One pointer event as the listener that caught it names its phase. origin is the canvas’s top-left in client coordinates, so the sample is in the canvas’s own CSS pixels.
