/**
|
|
* CheckOutItemView - provides a panel for the display of a single item in an Order
|
|
*
|
|
* This class displays the Order item with a field for adjusting the quantity and an
|
|
* optional thumbnail image of the item.
|
|
*
|
|
* If Modifiable is false the quantity field is a label and not adjustable, if true it is an
|
|
* input field allowing the user to change the quantity of the item.
|
|
*
|
|
*@todo
|
|
* - implement image support
|
|
* - base class most of this and use for ShoppingCartItemView as well, perhaps renaming to
|
|
* the more generic term OrderItemView; this needs to provide functionality like a DataGrid
|
|
* keeping an array of columns with AddColumn(foo) ..
