Struct EventCtx 

pub struct EventCtx<'a, Ext: 'static> {
    pub event: &'a mut Event,
    pub dom: &'a mut Dom<Ext>,
}

Context passed to a handler: mutable Event + mutable Dom.

Fields

event: &'a mut Event

dom: &'a mut Dom<Ext>

Implementations

impl<Ext: 'static> EventCtx<'_, Ext>

pub fn request_redraw(&mut self)

Ask the rendering host to repaint after this event completes.

Mutations made through ctx.dom are already seen by the host’s mutation tracker. Use this for the case the tracker can’t see: a handler that changed state living outside the DOM that the next paint will read — e.g. a <canvas> whose paint callback reads external application state. Without this, such a change produces no repaint until something else dirties the tree.

Sets a flag on the event (Event::redraw_requested) that the host harvests after dispatch; rdom-core itself does nothing with it.
