ColorPicker (React)

The ColorPicker control is a panel that allows users to pick colors. It is used as a drop-down by the InputColor control. You can customize the ColorPicker by changing the value of the showAlphaChannel, showColorString, and palette properties as in the sample below.

This example uses React.

import 'bootstrap.css'; import '@grapecity/wijmo.styles/wijmo.css'; import './app.css'; import * as React from 'react'; import * as ReactDOM from 'react-dom'; import * as wjInput from '@grapecity/wijmo.react.input'; import { getPalettes } from './data'; class App extends React.Component { constructor(props) { super(props); this._onShowAlphaChannelChange = (e) => { this.setState({ showAlphaChannel: e.target.checked }); }; this._onShowColorStringChange = (e) => { this.setState({ showColorString: e.target.checked }); }; this._onPaletteChanged = (sender) => { this.setState({ palette: sender.selectedItem.colors }); }; this._onValueChanged = (sender) => { this.setState({ color: sender.value }); }; this._palettes = getPalettes(); this.state = { showColorString: true, showAlphaChannel: true, color: '', palette: this._palettes[0].colors }; } render() { return <div className="container-fluid"> <div id="output" style={{ "background": this.state.color }}> Select a background for me! </div> <div className="form-check"> <label htmlFor="showAlphaChannel" className="form-check-label">showAlphaChannel:</label> <input id="showAlphaChannel" className="form-check-input" type="checkbox" onChange={this._onShowAlphaChannelChange} defaultChecked={this.state.showAlphaChannel}/> </div> <div className="form-check"> <label htmlFor="showColorString" className="form-check-label">showColorString:</label> <input id="showColorString" className="form-check-input" type="checkbox" onChange={this._onShowColorStringChange} defaultChecked={this.state.showColorString}/> </div> <div className="form-check"> <label htmlFor="thePalette">palette: </label> <wjInput.ComboBox displayMemberPath="name" itemsSource={this._palettes} selectedIndexChanged={this._onPaletteChanged}> </wjInput.ComboBox> </div> <wjInput.ColorPicker palette={this.state.palette} showAlphaChannel={this.state.showAlphaChannel} showColorString={this.state.showColorString} valueChanged={this._onValueChanged}> </wjInput.ColorPicker> </div>; } } ReactDOM.render(<App />, document.getElementById('app'));
