Enum DragResult 

#[non_exhaustive]
pub enum DragResult {
    Success,
    NoTarget,
    UserCancelled,
    TimeoutExpired,
    GrabBroken,
    Error,
}

Gives an indication why a drag operation failed. The value can by obtained by connecting to the drag-failed signal.

Variants (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.

Success

The drag operation was successful.

NoTarget

No suitable drag target.

UserCancelled

The user cancelled the drag operation.

TimeoutExpired

The drag operation timed out.

GrabBroken

The pointer or keyboard grab used for the drag operation was broken.

Error

The drag operation failed due to some unspecified error.
