Constructor Detail

BrowserCellList

public BrowserCellList(Cell<T> cell,
                       int level,
                       ProvidesKey<T> keyProvider)

Method Detail

deselectValue

protected void deselectValue()

getCellParent

protected Element getCellParent(Element item)

Description copied from class: CellList

Get the parent element that wraps the cell from the list item. Override this method if you add structure to the element.

Overrides:

getCellParent in class CellList<T>

Parameters:

item - the row element that wraps the list item

Returns:

the parent element of the cell

isKeyboardNavigationSuppressed

protected boolean isKeyboardNavigationSuppressed()

Description copied from class: AbstractHasData

Check if keyboard navigation is being suppressed, such as when the user is editing a cell.

Overrides:

isKeyboardNavigationSuppressed in class CellList<T>

Returns:

true if suppressed, false if not

onBrowserEvent2

protected void onBrowserEvent2(Event event)

Description copied from class: AbstractHasData

Called after AbstractHasData.onBrowserEvent(Event) completes.

Overrides:

onBrowserEvent2 in class CellList<T>

Parameters:

event - the event that was fired

renderRowValues

protected void renderRowValues(SafeHtmlBuilder sb,
                               java.util.List<T> values,
                               int start,
                               SelectionModel<? super T> selectionModel)

Description copied from class: AbstractHasData

Render all row values into the specified SafeHtmlBuilder.

Subclasses can optionally throw an UnsupportedOperationException if they prefer to render the rows in AbstractHasData.replaceAllChildren(List, SafeHtml) and AbstractHasData.replaceChildren(List, int, SafeHtml). In this case, the SafeHtml argument will be null. Though a bit hacky, this is designed to supported legacy widgets that use SafeHtmlBuilder, and newer widgets that use other builders, such as the ElementBuilder API.

Overrides:

renderRowValues in class CellList<T>

Parameters:

sb - the SafeHtmlBuilder to render into

values - the row values

start - the absolute start index of the values

selectionModel - the SelectionModel

setKeyboardSelected

protected void setKeyboardSelected(int index,
                                   boolean selected,
                                   boolean stealFocus)

Description copied from class: AbstractHasData

Update an element to reflect its keyboard selected state.

Overrides:

setKeyboardSelected in class CellList<T>

Parameters:

index - the index of the element

selected - true if selected, false if not

stealFocus - true if the row should steal focus, false if not

setSelectedValue

protected void setSelectedValue(T value)

Set the selected value in this list. If there is already a selected value, the old value will be deselected.

Parameters:

value - the selected value
