/** * The Modern Grid's ViewOptions plugin produces a menu that slides in from the right * (by default) when you longpress on the grid headers. The menu displays the column * header names which represents the order of the grid's columns. This allows users to * easily reorder the grid's columns by reordering the rows. Items may be dragged by * grabbing the furthest left side of the row and moving the item vertically. * * Once the columns are ordered to your liking, you may then close the menu by tapping the * "Done" button. * * @example * var store = Ext.create('Ext.data.Store', { * fields: ['name', 'email', 'phone'], * data: [{ * name: 'Lisa', * email: '[email protected]', * phone: '555-111-1224' * }, { * name: 'Bart', * email: '[email protected]', * phone: '555-111-1234' * }, { * name: 'Homer', * email: '[email protected]', * phone: '555-222-1244' * }, { * name: 'Marge', * email: '[email protected]', * phone: '555-222-1254' * }] * }); * * Ext.create('Ext.grid.Grid', { * store: store, * plugins: { * gridviewoptions: true * }, * columns: [{ * text: 'Name', * dataIndex: 'name', * width: 200 * }, { * text: 'Email', * dataIndex: 'email', * width: 250 * }, { * text: 'Phone', * dataIndex: 'phone', * width: 120 * }], * fullscreen: true * }); * * Developers may modify the menu and its contents by overriding {@link #sheet} and * {@link #columnList} respectively. * */Ext.define('Ext.grid.plugin.ViewOptions', { extend: 'Ext.plugin.Abstract', alias: 'plugin.gridviewoptions', requires: [ 'Ext.dataview.NestedList', 'Ext.dataview.plugin.SortableList', 'Ext.grid.plugin.ViewOptionsListItem' ], config: { /** * @private */ grid: null, /** * The width of the menu */ sheetWidth: 320, /** * The configuration of the menu */ sheet: { lazy: true, $value: { xtype: 'sheet', cls: Ext.baseCSSPrefix + 'gridviewoptions', items: [{ docked: 'top', xtype: 'titlebar', title: 'Customize', items: [{ xtype: 'button', text: 'Done', ui: 'action', align: 'right', role: 'donebutton' }] }], hidden: true, hideOnMaskTap: true, enter: 'right', exit: 'right', modal: true, right: 0, layout: 'fit', stretchY: true } }, /** * The column's configuration */ columnList: { lazy: true, $value: { xtype: 'nestedlist', title: 'Columns', clearSelectionOnListChange: false, listConfig: { triggerEvent: null, infinite: true, mode: 'MULTI', variableHeights: true, plugins: { sortablelist: { source: { handle: '.' + Ext.baseCSSPrefix + 'column-options-sortablehandle' } } }, itemConfig: { xtype: 'viewoptionslistitem' }, itemTpl: '{text}' }, store: { type: 'tree', fields: [ 'id', 'text', 'dataIndex', 'header', 'hidden', 'hideable', 'grouped', 'groupable' ], root: { text: 'Columns' } } } }, /** * The CSS class responsible for displaying the visibility indicator. */ visibleIndicatorSelector: '.' + Ext.baseCSSPrefix + 'column-options-visibleindicator', /** * The CSS class responsible for displaying the grouping indicator. */ groupIndicatorSelector: '.' + Ext.baseCSSPrefix + 'column-options-groupindicator' }, init: function(grid) { this.setGrid(grid);
