Package pamViewFX.fxNodes

Class PamListSpinnerFactory<T extends Number & Comparable>

java.lang.Object

javafx.scene.control.SpinnerValueFactory<T>

pamViewFX.fxNodes.PamListSpinnerFactory<T>

Type Parameters:

T - The type of the elements in the List. Must extends number

public class PamListSpinnerFactory<T extends Number & Comparable>
extends javafx.scene.control.SpinnerValueFactory<T>

A SpinnerValueFactory implementation designed to iterate through a list of values. This also enables users to set the value. The list has space for one extra set value. When a value which is not part of the list is set, then the it is placed in the list in sorted order. When a new setValue() is called with a number which is not present in the list then the previous set value is deleted.

 setConverter(new StringConverter<T>() {
        @Override
        public String toString(T value) {
                if (value == null) {
                        return "";
                }
                return value.toString();
        }

        @Override
        public T fromString(String string) {
                return (T) string;
        }
 });

Property Details

items

public final javafx.beans.property.ObjectProperty<javafx.collections.ObservableList<T extends Number & Comparable>> itemsProperty

Constructor Details

PamListSpinnerFactory

public PamListSpinnerFactory(javafx.collections.ObservableList<T> items)

Creates a new instance of the ListSpinnerValueFactory with the given list used as the list to step through.

Parameters:

items - The list of items to step through with the Spinner.

Method Details

setItems

public final void setItems(javafx.collections.ObservableList<T> value)

Sets the underlying data model for the ListSpinnerValueFactory. Note that it has a generic type that must match the type of the Spinner itself.

Parameters:

value - the list of items

getItems

public final javafx.collections.ObservableList<T> getItems()

Returns an ObservableList that contains the items currently able to be iterated through by the user. This may be null if setItems(javafx.collections.ObservableList) has previously been called, however, by default it is an empty ObservableList.

Returns:

An ObservableList containing the items to be shown to the user, or null if the items have previously been set to null.

itemsProperty

public final javafx.beans.property.ObjectProperty<javafx.collections.ObservableList<T>> itemsProperty()

The underlying data model for the ListView. Note that it has a generic type that must match the type of the ListView itself.

Returns:

the list of items
