Method Detail

getModelItem

protected T getModelItem(int index)

Description copied from class: SingleSelectionModel

Gets the data model item associated with a specific index.

Specified by:

getModelItem in class SingleSelectionModel<T>

Parameters:

index - The position of the item in the underlying data model.

Returns:

The item that exists at the given index.

getItemCount

protected int getItemCount()

Description copied from class: SingleSelectionModel

Gets the number of items available for the selection model. If the number of items can change dynamically, it is the responsibility of the concrete SingleSelectionModel implementation to ensure that items are selected or unselected as appropriate as the items change.

Specified by:

getItemCount in class SingleSelectionModel<T>

Returns:

A number greater than or equal to 0.

select

public void select(int index)

Selects the given row. Since the SingleSelectionModel can only support having a single row selected at a time, this also causes any previously selected row to be unselected. This method is overridden here so that we can move past a Separator in a ChoiceBox and select the next valid menuitem.

Overrides:

select in class SingleSelectionModel<T>

Parameters:

index - The position of the item to select in the selection model.

selectPrevious

public void selectPrevious()

Selects the previous index. Since the SingleSelectionModel can only support having a single index selected at a time, this also causes any previously selected index to be unselected.

Overrides:

selectPrevious in class SingleSelectionModel<T>

selectNext

public void selectNext()

Selects the next index. Since the SingleSelectionModel can only support having a single index selected at a time, this also causes any previously selected index to be unselected.

Overrides:

selectNext in class SingleSelectionModel<T>
