/**
|
|
* Adding this class to a {@link GridFieldConfig} of a {@link GridField} adds a header title to that field.
|
|
* The header serves double duty of displaying the name of the data the GridField is showing and
|
|
* providing an "add new" button to create new object instances.
|
|
*
|
|
* The reason for making "add new" part of the title component is to make it easier for the user to tell
|
|
* which "add new" button belongs to which datagrid, in the case where multiple datagrids are on a single
|
|
* page. It is also a more efficient use of screen space.
|
|
*
|
|
* The default DataGrid includes the add button. You can hide the button by setting a boolean using the
|
|
* setNewEnabled() method
