Enum SelectionChange 

pub enum SelectionChange {
    Replace(SharedString),
    Toggle(SharedString),
    Range {
        anchor: SharedString,
        to: SharedString,
    },
    Loaded,
    Everything,
    Clear,
}

What a gesture asked the selection to become.

The grid applies none of it. Every variant names rows by identity, and the two “all” variants are kept apart on purpose: a header checkbox can only speak for the rows the host has loaded, and claiming otherwise is the oldest lie in this part of the interface.

Variants

Replace(SharedString)

A plain click: this row and nothing else.

Toggle(SharedString)

A cmd or ctrl click: add this row, or take it away.

Range

A shift click: everything between the row last operated and this one. The host owns the order, so the host resolves the span.

Fields

anchor: SharedString

to: SharedString

Loaded

Every row the grid was given — which is every row the host has loaded, and may be fewer than exist.

Everything

Every row that exists, including the ones nobody has loaded. Only ever reported from a control that says that is what it does.

Clear
