- - com.google.gwt.user.client.ui.Widget
  - - com.google.gwt.user.client.ui.Composite
    - - com.google.gwt.user.client.ui.ResizeComposite
      - com.vaadin.client.widgets.Grid<T>

Type Parameters:

T - The row type of the grid. The row type is the POJO type from where the data is retrieved into the column cells.

All Implemented Interfaces:

com.google.gwt.event.logical.shared.HasAttachHandlers, com.google.gwt.event.shared.HasHandlers, com.google.gwt.user.client.EventListener, com.google.gwt.user.client.ui.Focusable, com.google.gwt.user.client.ui.HasEnabled, com.google.gwt.user.client.ui.HasVisibility, com.google.gwt.user.client.ui.HasWidgets, com.google.gwt.user.client.ui.IsRenderable, com.google.gwt.user.client.ui.IsWidget, com.google.gwt.user.client.ui.RequiresResize, DeferredWorker, SubPartAware, HasSelectionHandlers<T>, Iterable<com.google.gwt.user.client.ui.Widget>

public class Grid<T>
extends com.google.gwt.user.client.ui.ResizeComposite
implements HasSelectionHandlers<T>, SubPartAware, DeferredWorker, Focusable, com.google.gwt.user.client.ui.Focusable, com.google.gwt.user.client.ui.HasWidgets, com.google.gwt.user.client.ui.HasEnabled
```
A data grid view that supports columns and lazy loading of data rows from a data source.
Columns

Each column in Grid is represented by a Grid.Column. Each GridColumn has a custom implementation for Grid.Column.getValue(Object) that gets the row object as an argument, and returns the value for that particular column, extracted from the row object.
Each column also has a Renderer. Its function is to take the value that is given by the GridColumn and display it to the user. A simple column might have a TextRenderer that simply takes in a String and displays it as the cell's content. A more complex renderer might be ProgressBarRenderer that takes in a floating point number, and displays a progress bar instead, based on the given number.
See: addColumn(Column), addColumn(Column, int) and addColumns(Column...). Also Grid.Column.setRenderer(Renderer).
Data Sources

Grid gets its data from a DataSource, providing row objects to Grid from a user-defined endpoint. It can be either a local in-memory data source (e.g. ListDataSource) or even a remote one, retrieving data from e.g. a REST API (see AbstractRemoteDataSource).

```
public com.google.gwt.user.client.Element getSubPartElement(String subPart)

    Description copied from interface: SubPartAware
    
    Locates an element inside a component using the identifier provided in subPart. The subPart identifier is component specific and may be any string of characters, numbers, space characters and brackets.
    
    Specified by:
    
    getSubPartElement in interface SubPartAware
    
    Parameters:
    
    subPart - The identifier for the element inside the component
    
    Returns:
    
    The element identified by subPart or null if the element could not be found.
  - getSubPartName
```
public String getSubPartName(com.google.gwt.user.client.Element subElement)
```
    Description copied from interface: SubPartAware
    
    Provides an identifier that identifies the element within the component. The subElement is a part of the component and must never be null.
    Note! getSubPartElement(getSubPartName(element)) == element is not always true. A component can choose to provide a more generic identifier for any given element if the results of all interactions with subElement are the same as interactions with the element identified by the return value. For example a button can return an identifier for the root element even though a DIV inside the button was passed as subElement because interactions with the DIV and the root button element produce the same result.
    
    Specified by:
    
    getSubPartName in interface SubPartAware
    
    Parameters:
    
    subElement - The element the identifier string should uniquely identify
    
    Returns:
    
    An identifier that uniquely identifies subElement or null if no identifier could be provided.
