+ *
+ * Grids are an excellent way of showing large amounts of tabular data on the client side. Essentially a supercharged
+ * `<table>`, GridPanel makes it easy to fetch, sort and filter large amounts of data.
+ *
+ * Grids are composed of 2 main pieces - a {@link Ext.data.Store Store} full of data and a set of columns to render.
+ *
+ * {@img Ext.grid.Panel/Ext.grid.Panel1.png Ext.grid.Panel component}
+ *
+ * ## Basic GridPanel
+ *
+ * Ext.create('Ext.data.Store', {
+ * storeId:'simpsonsStore',
+ * fields:['name', 'email', 'phone'],
+ * data:{'items':[
+ * {"name":"Lisa", "email":"lisa@simpsons.com", "phone":"555-111-1224"},
+ * {"name":"Bart", "email":"bart@simpsons.com", "phone":"555--222-1234"},
+ * {"name":"Homer", "email":"home@simpsons.com", "phone":"555-222-1244"},
+ * {"name":"Marge", "email":"marge@simpsons.com", "phone":"555-222-1254"}
+ * ]},
+ * proxy: {
+ * type: 'memory',
+ * reader: {
+ * type: 'json',
+ * root: 'items'
+ * }
+ * }
+ * });
+ *
+ * Ext.create('Ext.grid.Panel', {
+ * title: 'Simpsons',
+ * store: Ext.data.StoreManager.lookup('simpsonsStore'),
+ * columns: [
+ * {header: 'Name', dataIndex: 'name'},
+ * {header: 'Email', dataIndex: 'email', flex:1},
+ * {header: 'Phone', dataIndex: 'phone'}
+ * ],
+ * height: 200,
+ * width: 400,
+ * renderTo: Ext.getBody()
+ * });
+ *
+ * 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 use the
+ * {@link #height}, {@link #width} and {@link #renderTo} configurations but they are included here to make it easy to get
+ * up and running.
+ *
+ * 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.
+ *
+ * ## Configuring columns
+ *
+ * By default, each column is sortable and will toggle between ASC and DESC sorting when you click on its header. Each
+ * column header is also reorderable by default, and each gains a drop-down menu with options to hide and show columns.
+ * It's easy to configure each column - here we use the same example as above and just modify the columns config:
+ *
+ * columns: [
+ * {
+ * header: 'Name',
+ * dataIndex: 'name',
+ * sortable: false,
+ * hideable: false,
+ * flex: 1
+ * },
+ * {
+ * header: 'Email',
+ * dataIndex: 'email',
+ * hidden: true
+ * },
+ * {
+ * header: 'Phone',
+ * dataIndex: 'phone',
+ * width: 100
+ * }
+ * ]
+ *
+ * We turned off sorting and hiding 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 menu on any other column). We also set the Phone column to
+ * a fixed with of 100px and flexed the Name column, which means it takes up all remaining width after the other columns
+ * have been accounted for. See the {@link Ext.grid.column.Column column docs} for more details.
+ *
+ * ## Renderers
+ *
+ * As well as customizing columns, it's easy to alter the rendering of individual cells using renderers. A renderer is
+ * tied to a particular column and is passed the value that would be rendered into each cell in that column. For example,
+ * we could define a renderer function for the email column to turn each email address into a mailto link:
+ *
+ * columns: [
+ * {
+ * header: 'Email',
+ * dataIndex: 'email',
+ * renderer: function(value) {
+ * return Ext.String.format('<a href="mailto:{0}">{1}</a>', value, value);
+ * }
+ * }
+ * ]
+ *
+ * See the {@link Ext.grid.column.Column column docs} for more information on renderers.
+ *
+ * ## Selection Models
+ *
+ * Sometimes all you want is to render data onto the screen for viewing, but usually it's necessary to interact with or
+ * update that data. Grids use a concept called a Selection Model, which is simply a mechanism for selecting some part of
+ * the data in the grid. The two main types of Selection Model are RowSelectionModel, where entire rows are selected, and
+ * CellSelectionModel, where individual cells are selected.
+ *
+ * Grids use a Row Selection Model by default, but this is easy to customise like so:
+ *
+ * Ext.create('Ext.grid.Panel', {
+ * selType: 'cellmodel',
+ * store: ...
+ * });
+ *
+ * Specifying the `cellmodel` changes a couple of things. Firstly, clicking on a cell now
+ * selects just that cell (using a {@link Ext.selection.RowModel rowmodel} will select the entire row), and secondly the
+ * keyboard navigation will walk from cell to cell instead of row to row. Cell-based selection models are usually used in
+ * conjunction with editing.
+ *
+ * {@img Ext.grid.Panel/Ext.grid.Panel2.png Ext.grid.Panel cell editing}
+ *
+ * ## Editing
+ *
+ * Grid has built-in support for in-line editing. There are two chief editing modes - cell editing and row editing. Cell
+ * editing is easy to add to your existing column setup - here we'll just modify the example above to include an editor
+ * on both the name and the email columns:
+ *
+ * Ext.create('Ext.grid.Panel', {
+ * title: 'Simpsons',
+ * store: Ext.data.StoreManager.lookup('simpsonsStore'),
+ * columns: [
+ * {header: 'Name', dataIndex: 'name', field: 'textfield'},
+ * {header: 'Email', dataIndex: 'email', flex:1,
+ * field:{
+ * xtype:'textfield',
+ * allowBlank:false
+ * }
+ * },
+ * {header: 'Phone', dataIndex: 'phone'}
+ * ],
+ * selType: 'cellmodel',
+ * plugins: [
+ * Ext.create('Ext.grid.plugin.CellEditing', {
+ * clicksToEdit: 1
+ * })
+ * ],
+ * height: 200,
+ * width: 400,
+ * renderTo: Ext.getBody()
+ * });
+ *
+ * This requires a little explanation. We're passing in {@link #store store} and {@link #columns columns} as normal, but
+ * this time we've also specified a {@link #field field} on two of our columns. For the Name column we just want a default
+ * textfield to edit the value, so we specify 'textfield'. For the Email column we customized the editor slightly by
+ * passing allowBlank: false, which will provide inline validation.
+ *
+ * To support cell editing, we also specified that the grid should use the 'cellmodel' {@link #selType}, and created an
+ * instance of the {@link Ext.grid.plugin.CellEditing CellEditing plugin}, which we configured to activate each editor after a
+ * single click.
+ *
+ * {@img Ext.grid.Panel/Ext.grid.Panel3.png Ext.grid.Panel row editing}
+ *
+ * ## Row Editing
+ *
+ * The other type of editing is row-based editing, using the RowEditor component. This enables you to edit an entire row
+ * at a time, rather than editing cell by cell. Row Editing works in exactly the same way as cell editing, all we need to
+ * do is change the plugin type to {@link Ext.grid.plugin.RowEditing}, and set the selType to 'rowmodel':
+ *
+ * Ext.create('Ext.grid.Panel', {
+ * title: 'Simpsons',
+ * store: Ext.data.StoreManager.lookup('simpsonsStore'),
+ * columns: [
+ * {header: 'Name', dataIndex: 'name', field: 'textfield'},
+ * {header: 'Email', dataIndex: 'email', flex:1,
+ * field:{
+ * xtype:'textfield',
+ * allowBlank:false
+ * }
+ * },
+ * {header: 'Phone', dataIndex: 'phone'}
+ * ],
+ * selType: 'rowmodel',
+ * plugins: [
+ * Ext.create('Ext.grid.plugin.RowEditing', {
+ * clicksToEdit: 1
+ * })
+ * ],
+ * height: 200,
+ * width: 400,
+ * renderTo: Ext.getBody()
+ * });
+ *
+ * Again we passed some configuration to our {@link Ext.grid.plugin.RowEditing} plugin, and now when we click each row a row
+ * editor will appear and enable us to edit each of the columns we have specified an editor for.
+ *
+ * ## 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'},
+ * ]);
+ *
+ * {@img Ext.grid.Panel/Ext.grid.Panel4.png Ext.grid.Panel grouping}
+ *
+ * ## Grouping
+ *
+ * Grid supports the grouping of rows by any field. For example if we had a set of employee records, we might want to
+ * group by the department that each employee works in. Here's how we might set that up:
+ *
+ * var store = Ext.create('Ext.data.Store', {
+ * storeId:'employeeStore',
+ * fields:['name', 'senority', 'department'],
+ * groupField: 'department',
+ * data:{'employees':[
+ * {"name":"Michael Scott", "senority":7, "department":"Manangement"},
+ * {"name":"Dwight Schrute", "senority":2, "department":"Sales"},
+ * {"name":"Jim Halpert", "senority":3, "department":"Sales"},
+ * {"name":"Kevin Malone", "senority":4, "department":"Accounting"},
+ * {"name":"Angela Martin", "senority":5, "department":"Accounting"}
+ * ]},
+ * proxy: {
+ * type: 'memory',
+ * reader: {
+ * type: 'json',
+ * root: 'employees'
+ * }
+ * }
+ * });
+ *
+ * Ext.create('Ext.grid.Panel', {
+ * title: 'Employees',
+ * store: Ext.data.StoreManager.lookup('employeeStore'),
+ * columns: [
+ * {header: 'Name', dataIndex: 'name'},
+ * {header: 'Senority', dataIndex: 'senority'}
+ * ],
+ * features: [{ftype:'grouping'}],
+ * width: 200,
+ * height: 275,
+ * renderTo: Ext.getBody()
+ * });
+ *
+ * ## Infinite Scrolling
+ *
+ * Grid supports infinite scrolling as an alternative to using a paging toolbar. Your users can scroll through thousands
+ * of records without the performance penalties of renderering all the records on screen at once. The grid should be bound
+ * to a store with a pageSize specified.
+ *
+ * var grid = Ext.create('Ext.grid.Panel', {
+ * // Use a PagingGridScroller (this is interchangeable with a PagingToolbar)
+ * verticalScrollerType: 'paginggridscroller',
+ * // do not reset the scrollbar when the view refreshs
+ * invalidateScrollerOnRefresh: false,
+ * // infinite scrolling does not support selection
+ * disableSelection: true,
+ * // ...
+ * });
+ *
+ * ## Paging
+ *
+ * Grid supports paging through large sets of data via a PagingToolbar or PagingGridScroller (see the Infinite Scrolling section above).
+ * To leverage paging via a toolbar or scroller, you need to set a pageSize configuration on the Store.
+ *
+ * var itemsPerPage = 2; // set the number of items you want per page
+ *
+ * var store = Ext.create('Ext.data.Store', {
+ * id:'simpsonsStore',
+ * autoLoad: false,
+ * fields:['name', 'email', 'phone'],
+ * pageSize: itemsPerPage, // items per page
+ * proxy: {
+ * type: 'ajax',
+ * url: 'pagingstore.js', // url that will load data with respect to start and limit params
+ * reader: {
+ * type: 'json',
+ * root: 'items',
+ * totalProperty: 'total'
+ * }
+ * }
+ * });
+ *
+ * // specify segment of data you want to load using params
+ * store.load({
+ * params:{
+ * start:0,
+ * limit: itemsPerPage
+ * }
+ * });
+ *
+ * Ext.create('Ext.grid.Panel', {
+ * title: 'Simpsons',
+ * store: store,
+ * columns: [
+ * {header: 'Name', dataIndex: 'name'},
+ * {header: 'Email', dataIndex: 'email', flex:1},
+ * {header: 'Phone', dataIndex: 'phone'}
+ * ],
+ * width: 400,
+ * height: 125,
+ * dockedItems: [{
+ * xtype: 'pagingtoolbar',
+ * store: store, // same store GridPanel is using
+ * dock: 'bottom',
+ * displayInfo: true
+ * }],
+ * renderTo: Ext.getBody()
+ * });
