ColorPicker

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.

import 'bootstrap.css'; import '@grapecity/wijmo.styles/wijmo.css'; import './styles.css'; // import * as input from '@grapecity/wijmo.input'; import { getPalettes } from './data'; // document.readyState === 'complete' ? init() : window.onload = init; // function init() { // ColorPicker let theColorPicker = new input.ColorPicker('#theColorPicker', { showAlphaChannel: true, showColorString: true, valueChanged: (sender) => setBackground(sender.value) }); // // customization document.querySelector('#showAlphaChannel').addEventListener('click', e => { theColorPicker.showAlphaChannel = e.target.checked; }); document.querySelector('#showColorString').addEventListener('click', e => { theColorPicker.showColorString = e.target.checked; }); // let thePalette = new input.ComboBox('#thePalette', { itemsSource: getPalettes(), displayMemberPath: 'name', selectedIndexChanged: (sender) => { theColorPicker.palette = sender.selectedValue.colors; } }); // // show the color that was selected function setBackground(color) { document.getElementById('output').style.background = color; theColorPicker.value = color; } }
