#[non_exhaustive]
pub enum NotifyType {
    Ancestor,
    Virtual,
    Inferior,
    Nonlinear,
    NonlinearVirtual,
    Unknown,
}
Expand description

Specifies the kind of crossing for enter and leave events.

See the X11 protocol specification of LeaveNotify for full details of crossing event generation.

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.
§

Ancestor

the surface is entered from an ancestor or left towards an ancestor.

§

Virtual

the pointer moves between an ancestor and an inferior of the surface.

§

Inferior

the surface is entered from an inferior or left towards an inferior.

§

Nonlinear

the surface is entered from or left towards a surface which is neither an ancestor nor an inferior.

§

NonlinearVirtual

the pointer moves between two surfaces which are not ancestors of each other and the surface is part of the ancestor chain between one of these surfaces and their least common ancestor.

§

Unknown

an unknown type of enter/leave event occurred.
