/** * Grids are an excellent way of showing large amounts of tabular data on the client side. * Essentially a supercharged `<table>`, Grid makes it easy to fetch, sort and filter large * amounts of data. * * Grids are composed of two main pieces - a {@link Ext.data.Store Store} full of data and * a set of columns to render. * * ## A Basic Grid * * 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":"555-222-1234" }, * { 'name': 'Homer', "email":"[email protected]", "phone":"555-222-1244" }, * { 'name': 'Marge', "email":"[email protected]", "phone":"555-222-1254" } * ] * }); * * Ext.create('Ext.grid.Grid', { * title: 'Simpsons', * * store: store, * * columns: [ * { text: 'Name', dataIndex: 'name', width: 200 }, * { text: 'Email', dataIndex: 'email', width: 250 }, * { text: 'Phone', dataIndex: 'phone', width: 120 } * ], * * height: 200, * layout: 'fit', * fullscreen: true * }); * * The code above produces a simple grid with three columns. We specified a Store which will * load JSON data inline. In most apps we would be placing the grid inside another container * and wouldn't need to provide the {@link #height}, {@link #width} and * {@link #cfg-fullscreen} options but they are included here to for demonstration. * * The grid we created above will contain a header bar with a title ('Simpsons'), a row of * column headers directly underneath and finally the grid rows under the headers. * * ## Columns * * By default, each {@link Ext.grid.column.Column column} is sortable and toggles between * ascending and descending sorting when you click on its header. There are several basic * configs that can be applied to columns to change these behaviors. For example: * * columns: [ * { * text: 'Name', * dataIndex: 'name', * sortable: false, // column cannot be sorted * width: 250 * }, * { * text: 'Email', * dataIndex: 'email', * hidden: true // column is initially hidden * }, * { * text: 'Phone', * dataIndex: 'phone', * width: 100 * } * ] * * We turned off sorting on the 'Name' column so clicking its header now has no effect. We * also made the Email column hidden by default (it can be shown again by using the * {@link Ext.grid.plugin.ViewOptions ViewOptions} plugin). See the * {@link Ext.grid.column.Column column class} for more details. * * A top-level column definition may contain a `columns` configuration. This means that the * resulting header will be a group header, and will contain the child columns. * * ## Rows and Cells * * Grid extends the `{@link Ext.dataview.List List}` component and connects records in the * store to `{@link Ext.grid.Row row components}` for the list's items. The Row component * utilizes the configs of the grid's {@link Ext.grid.column.Column columns} to create the * appropriate type of {@link Ext.grid.cell.Base cells}. Essentially, a Row is a container * for {@link Ext.Widget Cell widgets}. * * For the most part, configuring a grid is about configuring the columns and their cells. * There are several built-in column types to display specific types of data: * * - {@link Ext.grid.column.Boolean} for true/false values. * - {@link Ext.grid.column.Date} for date/time values. * - {@link Ext.grid.column.Number} for numeric values. * * These columns specify (via their {@link Ext.grid.column.Column#cell cell config}) one * of these basic cell widget types: * * - {@link Ext.grid.cell.Boolean} * - {@link Ext.grid.cell.Date} * - {@link Ext.grid.cell.Number} * * In addition to the above basic cell types, there are two other useful cell types to * know about: * * - {@link Ext.grid.cell.Text} is the base class for the boolean, date and number cell * classes. It is useful when a cell contains only text. * - {@link Ext.grid.cell.Widget} is a cell class that manages a single child item (either * a {@link Ext.Component component} or a {@link Ext.Widget widget}). The child item is * configured using the `{@link Ext.grid.cell.Widget#widget widget config}`. The most * important part of this config is the `xtype` of the child item to create. * * ## Cells and Binding * * One technique to controll cell content and styling is to use data binding to target * cell configs like {@link Ext.grid.cell.Base#cls} and {@link Ext.grid.cell.Base#bodyCls}. * This is done by assigning a {@link Ext.app.ViewModel viewModel} to each Row like so: * * itemConfig: { * viewModel: true // create default ViewModel for each item (i.e., Row) * } * * Now that each Row has a ViewModel, cells can bind to the fields of the associated record * like so: * * columns: [{ * ... * cell: { * bind: { * cls: '{record.someCls}' * } * } * }] * * The "record" property in the ViewModel is managed by the Row. As Row instances are * recycled due to buffered rendering, the associated record instance simply changes over * time. * * ### Cell Widgets * * When using {@link Ext.grid.cell.Widget}, the contained widgets can also use binding to * configure themsleves using properties of the associated record. * * columns: [{ * ... * cell: { * xtype: 'widgetcell', * widget: { * xtype: 'button', * bind: { * text: 'Update {record.firstName}' * } * } * } * }] * * ### Row ViewModels * * In some cases a custom ViewModel could be useful, for example to provide useful values * via {@link Ext.app.ViewModel#formulas formulas}. * * itemConfig: { * viewModel: { * type: 'rowViewModel' * } * } * * ## Renderers and Templates * * Columns provide two other mechanisms to format their cell content: * * - {@link Ext.grid.column.Column#renderer} * - {@link Ext.grid.column.Column#tpl} * * These column configs are processed by the {@link Ext.grid.column.Cell default cell type} * for a column. These configs have some downsides compared to data binding but are provided * for compatibility with previous releases. * * - Renderers and templates must update the cell content when _any_ field changes. They * cannot assume that only changes to the dataIndex will affect the rendering. Using * data binding, only the configs affected by the changed data will be updated. * - Updates are processed synchronously in response to the record update notification. * Contrast to ViewModels which provide a buffered update mechanism. * - Constructing HTML blocks in code (even in a template) is a common cause of security * problems such as XSS attacks. * * ## Sorting & Filtering * * Every grid is attached to a {@link Ext.data.Store Store}, which provides multi-sort and * filtering capabilities. It's easy to set up a grid to be sorted from the start: * * var myGrid = Ext.create('Ext.grid.Panel', { * store: { * fields: ['name', 'email', 'phone'], * sorters: ['name', 'phone'] * }, * columns: [ * { text: 'Name', dataIndex: 'name' }, * { text: 'Email', dataIndex: 'email' } * ] * }); * * Sorting at run time is easily accomplished by simply clicking each column header. If you * need to perform sorting on more than one field at run time it's easy to do so by adding * new sorters to the store: * * myGrid.store.sort([ * { property: 'name', direction: 'ASC' }, * { property: 'email', direction: 'DESC' } * ]); * * See {@link Ext.data.Store} for examples of filtering. * * ## Plugins * * Grid supports addition of extra functionality through plugins: * * - {@link Ext.grid.plugin.ViewOptions ViewOptions} - adds the ability to show/hide * columns and reorder them. * * - {@link Ext.grid.plugin.ColumnResizing ColumnResizing} - allows for the ability to * resize columns. * * - {@link Ext.grid.plugin.Editable Editable} - editing grid contents one row at a time. * * - {@link Ext.grid.plugin.RowOperations RowOperations} - selecting and performing tasks * on severalrows at a time (e.g. deleting them). * * - {@link Ext.grid.plugin.PagingToolbar PagingToolbar} - adds a toolbar at the bottom of * the grid that allows you to quickly navigate to another page of data. * * - {@link Ext.grid.plugin.SummaryRow SummaryRow} - adds and pins an additional row to the * top of the grid that enables you to display summary data. */Ext.define('Ext.grid.Grid', { extend: 'Ext.dataview.List', xtype: 'grid', isGrid: true, requires: [ 'Ext.TitleBar', 'Ext.grid.NavigationModel', 'Ext.grid.Row', 'Ext.grid.column.Column', 'Ext.grid.column.Date', 'Ext.grid.column.Template', 'Ext.grid.menu.*', 'Ext.grid.HeaderContainer', 'Ext.grid.selection.*', 'Ext.grid.plugin.ColumnResizing' ], mixins: [ 'Ext.mixin.ConfigProxy' ], storeEventListeners: { sort: 'onStoreSort' }, config: { /** * @cfg {Ext.grid.column.Column[]} columns (required) * An array of column definition objects which define all columns that appear in this grid. * Each column definition provides the header text for the column, and a definition of where * the data for that column comes from. * * This can also be a configuration object for a {Ext.grid.header.Container HeaderContainer} * which may override certain default configurations if necessary.
