// Types:
//
type DraggableEventHandler = (e: Event, data: DraggableData) => void | false;
type DraggableData = {
  node: HTMLElement,
  // lastX + deltaX === x
  x: number, y: number,
  deltaX: number, deltaY: number,
  lastX: number, lastY: number
};

//
// Props:
//
{
// If set to `true`, will allow dragging on non left-button clicks.
allowAnyClick: boolean,

// Default `false` and default behavior before 4.5.0.
// If set to `true`, the 'touchstart' event will not be prevented,
// which will allow scrolling inside containers. We recommend
// using the 'handle' / 'cancel' props when possible instead of enabling this.
// 
// See https://github.com/react-grid-layout/react-draggable/issues/728
allowMobileScroll: boolean,

// Determines which axis the draggable can move. This only affects
// flushing to the DOM. Callbacks will still include all values.
// Accepted values:
// - `both` allows movement horizontally and vertically (default).
// - `x` limits movement to horizontal axis.
// - `y` limits movement to vertical axis.
// - 'none' stops all movement.
axis: string,

// Specifies movement boundaries. Accepted values:
// - `parent` restricts movement within the node's offsetParent
//    (nearest node with position relative or absolute), or
// - a selector, restricts movement within the targeted node
// - An object with `left, top, right, and bottom` properties.
//   These indicate how far in each direction the draggable
//   can be moved.
bounds: {left?: number, top?: number, right?: number, bottom?: number} | string,

// Specifies a selector to be used to prevent drag initialization. The string is passed to
// Element.matches, so it's possible to use multiple selectors like `.first, .second`.
// Example: '.body'
cancel: string,

// Class names for draggable UI.
// Default to 'react-draggable', 'react-draggable-dragging', and 'react-draggable-dragged'
defaultClassName: string,
defaultClassNameDragging: string,
defaultClassNameDragged: string,

// Specifies the `x` and `y` that the dragged item should start at.
// This is generally not necessary to use (you can use absolute or relative
// positioning of the child directly), but can be helpful for uniformity in
// your callbacks and with css transforms.
defaultPosition: {x: number, y: number},

// If true, will not call any drag handlers.
disabled: boolean,

// Default `true`. Adds "user-select: none" while dragging to avoid selecting text.
enableUserSelectHack: boolean,

// Specifies the x and y that dragging should snap to.
grid: [number, number],

// Specifies a selector to be used as the handle that initiates drag.
// Example: '.handle'
handle: string,

// If desired, you can provide your own offsetParent for drag calculations.
// By default, we use the Draggable's offsetParent. This can be useful for elements
// with odd display types or floats.
offsetParent: HTMLElement,

// Called whenever the user mouses down. Called regardless of handle or
// disabled status.
onMouseDown: (e: MouseEvent) => void,

// Called when dragging starts. If `false` is returned any handler,
// the action will cancel.
onStart: DraggableEventHandler,

// Called while dragging.
onDrag: DraggableEventHandler,

// Called when dragging stops.
onStop: DraggableEventHandler,

// If running in React Strict mode, ReactDOM.findDOMNode() is deprecated.
// Unfortunately, in order for <Draggable> to work properly, we need raw access
// to the underlying DOM node. If you want to avoid the warning, pass a `nodeRef`
// as in this example:
//
// function MyComponent() {
//   const nodeRef = React.useRef(null);
//   return (
//     <Draggable nodeRef={nodeRef}>
//       <div ref={nodeRef}>Example Target</div>
//     </Draggable>
//   );
// }
//
// This can be used for arbitrarily nested components, so long as the ref ends up
// pointing to the actual child DOM node and not a custom component.
//
// For rich components, you need to both forward the ref *and props* to the underlying DOM
// element. Props must be forwarded so that DOM event handlers can be attached. 
// For example:
//
//   const Component1 = React.forwardRef(function (props, ref) {
//     return <div {...props} ref={ref}>Nested component</div>;
//   });
//
//   const nodeRef = React.useRef(null);
//   <DraggableCore onDrag={onDrag} nodeRef={nodeRef}>
//     <Component1 ref={nodeRef} />
//   </DraggableCore>
//
// Thanks to react-transition-group for the inspiration.
//
// `nodeRef` is also available on <DraggableCore>.
nodeRef: React.Ref<typeof React.Component>,

// Much like React form elements, if this property is present, the item
// becomes 'controlled' and is not responsive to user input. Use `position`
// if you need to have direct control of the element.
position: {x: number, y: number}

// A position offset to start with. Useful for giving an initial position
// to the element. Differs from `defaultPosition` in that it does not
// affect the position returned in draggable callbacks, and in that it
// accepts strings, like `{x: '10%', y: '10%'}`.
positionOffset: {x: number | string, y: number | string},

// Specifies the scale of the canvas your are dragging this element on. This allows
// you to, for example, get the correct drag deltas while you are zoomed in or out via
// a transform or matrix in the parent of this element.
scale: number
