Enum DragMsg 

pub enum DragMsg {
    Pressed(PathBuf, bool),
    Entered(PathBuf),
    Exited(PathBuf),
    Released(PathBuf),
    Cancelled,
}

Opaque drag-machinery event produced by the widget’s internal mouse-area instrumentation.

Applications should treat these as opaque payloads and route them back to DirectoryTree::update unchanged — exactly like LoadPayload. Apps generally never construct these variants by hand.

Variants

Pressed(PathBuf, bool)

Mouse button was pressed on a row. The bool indicates whether the row is a directory (relevant for valid-target checks later if that row happens to be the release point).

Entered(PathBuf)

Cursor entered a row while a drag is in progress. The widget decides whether the row is a valid drop target.

Exited(PathBuf)

Cursor left a row while a drag is in progress.

Released(PathBuf)

Mouse button was released on a row. The widget inspects its drag state to decide whether this was a click (same row as press → emit a delayed Selected), a successful drop (hover target set → emit DragCompleted), or a cancelled drag (release on non-target → quietly clear state).

Cancelled

External cancellation signal. Emitted by the widget itself when the user presses Escape while a drag is in flight, or by the application if it wants to abort a drag for its own reasons (e.g. a modal opened). Clearing drag state is idempotent, so this is safe to call speculatively.
