A React controlled component for WinBox.js, with full Reactful props and state. Includes all configurations of WinBox.js by using React component props.

Full type declaration for both JavaScript and TypeScript.

demo screenshot


npm install --save react-winbox
# OR
yarn add react-winbox


Ensure the document body has an initial non-zero height, e.g. 100vh.

import WinBox from 'react-winbox';

  width={this.state.boxWidth ?? 500}
    <h1>Hello, WinBox!</h1>
    <MyComponent myProps={1} onChange={this.handleChange}/>

Or you can do more one step, to make a genuine 'windows manager', just like:

// ...
// some code to maintain a list of necessary windows info...
// ...
const [windows, setWindows] = useState([]);

// This function is for manage `onclose` callback behavior and virtual DOM state.
const handleClose = (force, id) => {
  let state = [];
  const index = state.findIndex(info => === id);
  if (index !== -1) {
    if (state[index].onclose && state[index].onclose(force))
      return true;                       // window-specific onclose, returns true if it does not need the default close process.
    state.splice(index, 1);
    setTimeout(() => setWindows(state)); // (Notice 5)to change winbox showing state in `onclose`, MUST wrap it within `setTimeout`

return (
    { => (
        onclose={(force) => handleClose(force,}
        {} // assign any props you want to WinBox
        <div>Some children</div>


  1. To use React-WinBox, ensure the document body has an initial non-zero height, e.g. 100vh.
  2. To open a winbox, just create it in your virtual DOM, that's enough.
  3. To close a winbox, just do not render it. The winbox will be closed automatically, and it will call the onclose callback once with force=true param. If the winbox DOM has been closed before, it will do nothing and just be removed off the virtual DOM.
  4. onclose is called BEFORE the winbox DOM goes to the close process. If you want to use it to block the closing by users who pressed the close button (such as when there is something editable which has not been saved), it's useful.
  5. When onclose is called, the winbox DOM has not been removed, you may want to change the WinBox Component rendering state. Be sure to wrap state destroy actions within setTimeout so that they occur after the winbox DOM is truly removed,e.g. setTimeout(() => this.setState({showWindow: false})). Otherwise, the program-side closing (Notice 3) will overlie the user-side closing (Notice 4). That's cause trouble. See the handleClose function in the second usage for more about a completely safe state management behavior for both program-side and user-side closing.
  6. To change some properties of the window, just change the properties of the WinBox Component. (the properties need official methods support. BTW, don't forget to setState or forceUpdate to rerender the parent of the WinBox!)
  7. If you want to operate the pure WinBox.js object manually (In winbox@0.2.1, it's needed only when you want to call the mount() method), you can find a winBoxObj in the component ref. !!! Take care of the relationship of statement between WinBox Component and winBoxObj.

Props and Methods

See the official document for WinBox.js


most props are one-to-one corresponding to the params of WinBox.js.

type WinBoxPropType = {
  title: string
  id?: string
  children?: ReactElement | ReactElement[] | null
  url?: string // When you use this, the children elements will be ignored.

  noAnimation?: boolean,
  noShadow?: boolean,
  noHeader?: boolean,
  noMin?: boolean,
  noMax?: boolean,
  noFull?: boolean,
  noClose?: boolean,
  noResize?: boolean,
  noMove?: boolean,
  modal?: boolean,
  hide?: boolean,

  index?: number,
  border?: number,
  splitscreen?: boolean,
  background?: string,

  max?: boolean, // a wrapper prop for maximize() method
  min?: boolean, // a wrapper prop for minimize() method

  x?: string | number | 'center',
  y?: string | number | 'center',
  top?: string | number,
  bottom?: string | number,
  left?: string | number,
  right?: string | number,
  height?: string | number,
  width?: string | number,
  fullscreen?: boolean, // a wrapper prop for fullscreen() method

  // returns true if the winbox does not need the default close process, for example, when it needs a confirmation to close instead of being closed suddenly.
  // the param `force` indicates whether you should not abort the winbox to close. If it is true, you MUST return false or empty, or some problems will happen.
  onclose?: (force: boolean) => boolean | undefined | void,
  onmove?: (x: number, y: number) => any,
  onresize?: (width: number, height: number) => any,
  onblur?: () => any,
  onfocus?: () => any,

  className?: string | number,


use React Ref to call these methods

focus () => void // same as the native method.

getId () => string | undefined // a wrapper getter for the id field

isMax () => boolean // a wrapper getter for max field

isMin () => boolean // a wrapper getter for min field

isClosed () => boolean // REACT ONLY. Returns true if the winbox DOM element has been removed but the React component has not yet.

forceUpdate (callback?: () => void): void // REACT ONLY.
