Enum MultiContact 

pub enum MultiContact {
    First,
    All,
}

How many simultaneous contacts a node handles.

The default, First, is what every widget written before the touch programme assumes: one press at a time. Under it a second contact arriving on the node is terminated there — neither delivered to the node nor bubbled to an ancestor — which is what stops two fingers landing on a button inside a scroll area from starting a pan with the second finger.

Variants

First

Serve the first contact; refuse any other while it is live.

All

Serve every contact, each with its own live arena. What a multi-touch surface (a pinch-zoom canvas, a piano keyboard) declares.
