Enum SelectionMode

source
#[non_exhaustive]
pub enum SelectionMode { None, Single, Browse, Multiple, }
Expand description

Used to control what selections users are allowed to make.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

None

No selection is possible.

§

Single

Zero or one element may be selected.

§

Browse

Exactly one element is selected. In some circumstances, such as initially or during a search operation, it’s possible for no element to be selected with Browse. What is really enforced is that the user can’t deselect a currently selected element except by selecting another element.

§

Multiple

Any number of elements may be selected. The Ctrl key may be used to enlarge the selection, and Shift key to select between the focus and the child pointed to. Some widgets may also allow Click-drag to select a range of elements.
