The source code

/** - * @class Ext.grid.GridPanel - * @extends Ext.Panel - *

This class represents the primary interface of a component based grid control to represent data - * in a tabular format of rows and columns. The GridPanel is composed of the following:

- *

{@link Ext.data.Store Store} : The Model holding the data records (rows) - *
{@link Ext.grid.ColumnModel Column model} : Column makeup - *
{@link Ext.grid.GridView View} : Encapsulates the user interface - *
{@link Ext.grid.AbstractSelectionModel selection model} : Selection behavior - *

- *

Example usage:

- *

-    {@link #store}: new {@link Ext.data.Store}({
-        {@link Ext.data.Store#autoDestroy autoDestroy}: true,

Notes:

- *

Although this class inherits many configuration options from base classes, some of them - * (such as autoScroll, autoWidth, layout, items, etc) are not used by this class, and will - * have no effect.
A grid requires a width in which to scroll its columns, and a height in which to - * scroll its rows. These dimensions can either be set explicitly through the - * {@link Ext.BoxComponent#height height} and {@link Ext.BoxComponent#width width} - * configuration options or implicitly set by using the grid as a child item of a - * {@link Ext.Container Container} which will have a {@link Ext.Container#layout layout manager} - * provide the sizing of its child items (for example the Container of the Grid may specify - * {@link Ext.Container#layout layout}:'fit').
To access the data in a Grid, it is necessary to use the data model encapsulated - * by the {@link #store Store}. See the {@link #cellclick} event for more details.

/** + * @class Ext.grid.GridPanel + * @extends Ext.Panel + *

This class represents the primary interface of a component based grid control to represent data + * in a tabular format of rows and columns. The GridPanel is composed of the following:

+ *

{@link Ext.data.Store Store} : The Model holding the data records (rows) + *
{@link Ext.grid.ColumnModel Column model} : Column makeup + *
{@link Ext.grid.GridView View} : Encapsulates the user interface + *
{@link Ext.grid.AbstractSelectionModel selection model} : Selection behavior + *

+ *

Example usage:

+ *


+var grid = new Ext.grid.GridPanel({
+    {@link #store}: new {@link Ext.data.Store}({
+        {@link Ext.data.Store#autoDestroy autoDestroy}: true,

Notes:

+ *

Although this class inherits many configuration options from base classes, some of them + * (such as autoScroll, autoWidth, layout, items, etc) are not used by this class, and will + * have no effect.
A grid requires a width in which to scroll its columns, and a height in which to + * scroll its rows. These dimensions can either be set explicitly through the + * {@link Ext.BoxComponent#height height} and {@link Ext.BoxComponent#width width} + * configuration options or implicitly set by using the grid as a child item of a + * {@link Ext.Container Container} which will have a {@link Ext.Container#layout layout manager} + * provide the sizing of its child items (for example the Container of the Grid may specify + * {@link Ext.Container#layout layout}:'fit').
To access the data in a Grid, it is necessary to use the data model encapsulated + * by the {@link #store Store}. See the {@link #cellclick} event for more details.
