}

One phase of an external (OS) drag over a window. Positions are in the window’s logical coordinate space (top-left origin), already converted from the platform’s native coordinates.

Variants

Entered

The drag entered the window. data is the best-effort payload the source offers (fully populated where the platform exposes it during hover — e.g. macOS; possibly empty until drop on backends that only transfer bytes at drop time). Lets a drop target validate on hover.

Fields

data: ExternalDropData

Offered payload (files / text / URLs); may be empty until drop.

position: Point

Entry position in window-logical coordinates.

Moved

The pointer moved while the drag is over the window.

Fields

position: Point

Current position in window-logical coordinates.

Left

The drag left the window, or the OS cancelled the operation, without a drop.

Dropped

The user dropped. Carries the extracted payload and the drop position.

Fields

data: ExternalDropData

Files / text / URLs / raw MIME bytes extracted from the OS payload.

position: Point

Drop position in window-logical coordinates.

DragEnded

An outbound (app → OS) drag this window started has finished. Posted by the platform backend’s drag-source callback so the framework can notify the source widget’s on_drag_ended.

Fields

outcome: DropOutcome

How the OS drag resolved (copy / move into another app, or cancel).
