/** * A general picker class. {@link Ext.picker.Slot}s are used to organize multiple scrollable slots into a single picker. {@link #slots} is * the only necessary configuration. * * The {@link #slots} configuration with a few key values: * * - `name`: The name of the slot (will be the key when using {@link #getValues} in this {@link Ext.picker.Picker}). * - `title`: The title of this slot (if {@link #useTitles} is set to `true`). * - `data`/`store`: The data or store to use for this slot. * * Remember, {@link Ext.picker.Slot} class extends from {@link Ext.dataview.DataView}. * * ## Examples * * @example miniphone preview * var picker = Ext.create('Ext.Picker', { * slots: [ * { * name : 'limit_speed', * title: 'Speed', * data : [ * {text: '50 KB/s', value: 50}, * {text: '100 KB/s', value: 100}, * {text: '200 KB/s', value: 200}, * {text: '300 KB/s', value: 300} * ] * } * ] * }); * Ext.Viewport.add(picker); * picker.show(); * * You can also customize the top toolbar on the {@link Ext.picker.Picker} by changing the {@link #doneButton} and {@link #cancelButton} configurations: * * @example miniphone preview * var picker = Ext.create('Ext.Picker', { * doneButton: 'I\'m done!', * cancelButton: false, * slots: [ * { * name : 'limit_speed', * title: 'Speed', * data : [ * {text: '50 KB/s', value: 50}, * {text: '100 KB/s', value: 100}, * {text: '200 KB/s', value: 200}, * {text: '300 KB/s', value: 300} * ] * } * ] * }); * Ext.Viewport.add(picker); * picker.show(); * * Or by passing a custom {@link #toolbar} configuration: * * @example miniphone preview * var picker = Ext.create('Ext.Picker', { * doneButton: false, * cancelButton: false, * toolbar: { * ui: 'light', * title: 'My Picker!' * }, * slots: [ * { * name : 'limit_speed', * title: 'Speed', * data : [ * {text: '50 KB/s', value: 50}, * {text: '100 KB/s', value: 100}, * {text: '200 KB/s', value: 200}, * {text: '300 KB/s', value: 300} * ] * } * ] * }); * Ext.Viewport.add(picker); * picker.show(); */Ext.define('Ext.picker.Picker', { extend: 'Ext.Sheet', alias : 'widget.picker', alternateClassName: 'Ext.Picker', requires: ['Ext.picker.Slot', 'Ext.TitleBar', 'Ext.data.Model', 'Ext.util.InputBlocker'], isPicker: true, /** * @event pick * Fired when a slot has been picked * @param {Ext.Picker} this This Picker. * @param {Object} values The values of this picker's slots, in `{name:'value'}` format. * @param {Ext.picker.Slot} slot An instance of Ext.Picker.Slot that has been picked. */ /** * @event change * Fired when the value of this picker has changed the Done button has been pressed. * @param {Ext.picker.Picker} this This Picker. * @param {Object} values The values of this picker's slots, in `{name:'value'}` format. */ /** * @event cancel * Fired when the cancel button is tapped and the values are reverted back to * what they were. * @param {Ext.Picker} this This Picker. */ config: { /** * @cfg * @inheritdoc */ baseCls: Ext.baseCSSPrefix + 'picker', /** * @cfg {String/Mixed} doneButton * Can be either: * * - A {String} text to be used on the Done button. * - An {Object} as config for {@link Ext.Button}. * - `false` or `null` to hide it. * @accessor */ doneButton: true, /** * @cfg {String/Mixed} cancelButton * Can be either: * * - A {String} text to be used on the Cancel button. * - An {Object} as config for {@link Ext.Button}. * - `false` or `null` to hide it. * @accessor */ cancelButton: true, /** * @cfg {Boolean} useTitles * Generate a title header for each individual slot and use * the title configuration of the slot. * @accessor */ useTitles: false, /** * @cfg {Array} slots * An array of slot configurations. * * - `name` {String} - Name of the slot * - `data` {Array} - An array of text/value pairs in the format `{text: 'myKey', value: 'myValue'}` * - `title` {String} - Title of the slot.
