Type Parameters:

T - Model object type

Direct Known Subclasses:

DataGridView

public abstract class AbstractDataGridView<T>
extends DataViewBase<T>

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 Details

AbstractDataGridView

public AbstractDataGridView(String id,
 List<? extends ICellPopulator<T>> populators,
 IDataProvider<T> dataProvider)

Constructor

Parameters:

id - component id

populators - array of ICellPopulator objects that will be used to populate cell items

dataProvider - data provider

Method Details

internalGetPopulators

protected final List<? extends ICellPopulator<T>> internalGetPopulators()

newCellItem

protected Item<ICellPopulator<T>> newCellItem(String id,
 int index,
 IModel<ICellPopulator<T>> 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<T> newItem(String id,
 int index,
 IModel<T> 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<T>

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<T> newRowItem(String id,
 int index,
 IModel<T> 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<T>

See Also:

• DataViewBase.onDetach()

populateItem

protected final void populateItem(Item<T> item)

Description copied from class: RefreshingView

Populate the given Item container.

be careful 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<T>

Parameters:

item - The item to populate
