public abstract class AbstractDataGridView
extends DataViewBase

Acts as a base for data-grid views. Unlike a data view a data-grid view populates both rows and columns. The columns are populated by an array of provided ICellPopulator objects.

Constructor Detail

AbstractDataGridView

public AbstractDataGridView(java.lang.String id,
                            ICellPopulator[] populators,
                            IDataProvider dataProvider)
Constructor

Parameters:
id - component id
populators - array of ICellPopulator objects that will be used to populate cell items
dataProvider - data provider
Method Detail

internalGetPopulators

protected final ICellPopulator[] internalGetPopulators()

newCellItem

protected Item newCellItem(java.lang.String id,
                           int index,
                           IModel model)
Factory method for Item container that represents a cell.

Parameters:
id - component id for the new data item
index - the index of the new data item
model - the model for the new data item
Returns:
DataItem created DataItem
See Also:
Item, RefreshingView.newItem(String, int, IModel)

newItem

protected final Item newItem(java.lang.String id,
                             int index,
                             IModel model)
Description copied from class: RefreshingView
Factory method for Item container. Item containers are simple MarkupContainer used to aggregate the user added components for a row inside the view.

Overrides:
newItem in class RefreshingView
Parameters:
id - component id for the new data item
index - the index of the new data item
model - the model for the new data item
Returns:
DataItem created DataItem
See Also:
Item

newRowItem

protected Item newRowItem(java.lang.String id,
                          int index,
                          IModel model)
Factory method for Item container that represents a row.

Parameters:
id - component id for the new data item
index - the index of the new data item
model - the model for the new data item.
Returns:
DataItem created DataItem
See Also:
Item, RefreshingView.newItem(String, int, IModel)

onDetach

protected void onDetach()
Description copied from class: Component
Called to allow a component to detach resources after use. Overrides of this method MUST call the super implementation, the most logical place to do this is the last line of the override method.

Overrides:
onDetach in class DataViewBase
See Also:
DataViewBase.onDetach()

populateItem

protected final void populateItem(Item item)
Description copied from class: RefreshingView
Populate the given Item container.

be carefull to add any components to the item and not the view itself. So, don't do:

 add(new Label("foo", "bar"));
 
but:
 item.add(new Label("foo", "bar"));
 

Specified by:
populateItem in class RefreshingView
Parameters:
item - The item to populate

RefreshingView.populateItem(org.apache.wicket.markup.repeater.Item)
