Enum gdk::DragCancelReason

source · [−]

#[non_exhaustive]
pub enum DragCancelReason {
    NoTarget,
    UserCancelled,
    Error,
    // some variants omitted
}

Available on crate feature v3_20 only.

Expand description

Used in DragContext to the reason of a cancelled DND operation.

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.

`NoTarget`

There is no suitable drop target.

`UserCancelled`

Drag cancelled by the user

`Error`

Unspecified error.
