Editor Properties: (see get_editor_property/set_editor_property)

  • default_drag_visual (Widget): [Read-Write] The Drag Visual is the widget to display when dragging the item. Normally people create a new widget to represent the temporary drag.

  • offset (Vector2D): [Read-Write] A percentage offset (-1..+1) from the Pivot location, the percentage is of the desired size of the dragged visual.

  • on_drag_cancelled (OnDragDropMulticast): [Read-Write] On Drag Cancelled

  • on_dragged (OnDragDropMulticast): [Read-Write] On Dragged

  • on_drop (OnDragDropMulticast): [Read-Write] On Drop

  • payload (Object): [Read-Write] The payload of the drag operation. This can be any UObject that you want to pass along as dragged data. If you were building an inventory screen this would be the UObject representing the item being moved to another slot.
