Example with size

If you use size props, please manage state by yourself.

1<Resizable
2  size={{ width: this.state.width, height: this.state.height }}
3  onResizeStop={(e, direction, ref, d) => {
4    this.setState({
5      width: this.state.width + d.width,
6      height: this.state.height + d.height,
7    });
8  }}
9>
10  Sample with size
11</Resizable>

Props

defaultSize?: { width: (number | string), height: (number | string) };

Specifies the width and height that the dragged item should start at. For example, you can set 300, '300px', 50%. If both defaultSize and size omitted, set 'auto'.

defaultSize will be ignored when size set.

size?: { width: (number | string), height: (number | string) };

The size property is used to set the size of the component. For example, you can set 300, '300px', 50%.

Use size if you need to control size state by yourself.

className?: string;

The className property is used to set the custom className of a resizable component.

style?: { [key: string]: string };

The style property is used to set the custom style of a resizable component.

minWidth?: number | string;

The minWidth property is used to set the minimum width of a resizable component. Defaults to 10px.

minHeight?: number | string;

The minHeight property is used to set the minimum height of a resizable component. Defaults to 10px.

maxWidth?: number | string;

The maxWidth property is used to set the maximum width of a resizable component.

maxHeight?: number | string;

The maxHeight property is used to set the maximum height of a resizable component.

grid?: [number, number];

The grid property is used to specify the increments that resizing should snap to. Defaults to [1, 1].

lockAspectRatio?: boolean | number;

The lockAspectRatio property is used to lock aspect ratio. Set to true to lock the aspect ratio based on the initial size. Set to a numeric value to lock a specific aspect ratio (such as 16/9). If set to numeric, make sure to set initial height/width to values with correct aspect ratio. If omitted, set false.

lockAspectRatioExtraWidth?: number;

The lockAspectRatioExtraWidth property enables a resizable component to maintain an aspect ratio plus extra width. For instance, a video could be displayed 16:9 with a 50px side bar. If omitted, set 0.

lockAspectRatioExtraHeight?: number;

The lockAspectRatioExtraHeight property enables a resizable component to maintain an aspect ratio plus extra height. For instance, a video could be displayed 16:9 with a 50px header bar. If omitted, set 0.

bounds?: ('window' | 'parent' | HTMLElement);

Specifies resize boundaries.

handleStyles?: HandleStyles;

The handleStyles property is used to override the style of one or more resize handles. Only the axis you specify will have its handle style replaced. If you specify a value for right it will completely replace the styles for the right resize handle, but other handle will still use the default styles.

handleClasses?: HandleClassName;

The handleClasses property is used to set the className of one or more resize handles.

handleComponent?: HandleComponent;

The handleComponent property is used to pass a React Component to be rendered as one or more resize handle. For example, this could be used to use an arrow icon as a handle..

handleWrapperStyle?: { [key: string]: string };

The handleWrapperStyle property is used to override the style of resize handles wrapper.

handleWrapperClass?: string;

The handleWrapperClass property is used to override the className of resize handles wrapper.

enable?: ?Enable;

The enable property is used to set the resizable permission of a resizable component.

The permission of top, right, bottom, left, topRight, bottomRight, bottomLeft, topLeft direction resizing. If omitted, all resizer are enabled. If you want to permit only right direction resizing, set { top:false, right:true, bottom:false, left:false, topRight:false, bottomRight:false, bottomLeft:false, topLeft:false }.

onResizeStart?: ResizeStartCallBack;

ResizeStartCallBack type is below.

1type ResizeStartCallback = (
2  e: SyntheticMouseEvent<HTMLDivElement> | SyntheticTouchEvent<HTMLDivElement>,
3  dir: ResizableDirection,
4  refToElement: HTMLDivElement,
5) => void;

Calls when resizable component resize start.

2  event: MouseEvent | TouchEvent,
3  direction: ResizableDirection,
4  refToElement: HTMLDivElement,
5  delta: NumberSize,
6) => void;

Calls when resizable component resizing.

3  direction: ResizableDirection,
4  refToElement: HTMLDivElement,
