Class ListView<T>

javafx.scene.control.ListView<T>

Type Parameters:: T - This type is used to represent the type of the objects stored in the ListViews items ObservableList. It is also used in the selection model and focus model.

All Implemented Interfaces:: Styleable, EventTarget, Skinnable

@DefaultProperty("items")
public class ListView<T>
extends Control

A ListView displays a horizontal or vertical list of items from which the user may select, or with which the user may interact. A ListView is able to have its generic type set to represent the type of data in the backing model. Doing this has the benefit of making various methods in the ListView, as well as the supporting classes (mentioned below), type-safe. In addition, making use of the generic type supports substantially simplified development of applications making use of ListView, as all modern IDEs are able to auto-complete far more successfully with the additional type information.

Populating a ListView

A simple example of how to create and populate a ListView of names (Strings) is shown here:

 ObservableList<String> names = FXCollections.observableArrayList(
          "Julia", "Ian", "Sue", "Matthew", "Hannah", "Stephan", "Denise");
 ListView<String> listView = new ListView<String>(names);

The elements of the ListView are contained within the items ObservableList. This ObservableList is automatically observed by the ListView, such that any changes that occur inside the ObservableList will be automatically shown in the ListView itself. If passing the ObservableList in to the ListView constructor is not feasible, the recommended approach for setting the items is to simply call:

 ObservableList<T> content = ...
 listView.setItems(content);

The end result of this is, as noted above, that the ListView will automatically refresh the view to represent the items in the list.

Another approach, whilst accepted by the ListView, is not the recommended approach:

 List<T> content = ...
 getItems().setAll(content);

The issue with the approach shown above is that the content list is being copied into the items list - meaning that subsequent changes to the content list are not observed, and will not be reflected visually within the ListView.

ListView Selection / Focus APIs

To track selection and focus, it is necessary to become familiar with the SelectionModel and FocusModel classes. A ListView has at most one instance of each of these classes, available from selectionModel and focusModel properties respectively. Whilst it is possible to use this API to set a new selection model, in most circumstances this is not necessary - the default selection and focus models should work in most circumstances.

The default SelectionModel used when instantiating a ListView is an implementation of the MultipleSelectionModel abstract class. However, as noted in the API documentation for the selectionMode property, the default value is SelectionMode.SINGLE. To enable multiple selection in a default ListView instance, it is therefore necessary to do the following:

 listView.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);

Customizing ListView Visuals

The visuals of the ListView can be entirely customized by replacing the default cell factory. A cell factory is used to generate ListCell instances, which are used to represent an item in the ListView. See the Cell class documentation for a more complete description of how to write custom Cells.

Editing

This control supports inline editing of values, and this section attempts to give an overview of the available APIs and how you should use them.

Firstly, cell editing most commonly requires a different user interface than when a cell is not being edited. This is the responsibility of the Cell implementation being used. For ListView, this is the responsibility of the cell factory. It is your choice whether the cell is permanently in an editing state (e.g. this is common for CheckBox cells), or to switch to a different UI when editing begins (e.g. when a double-click is received on a cell).

To know when editing has been requested on a cell, simply override the Cell.startEdit() method, and update the cell text and graphic properties as appropriate (e.g. set the text to null and set the graphic to be a TextField). Additionally, you should also override Cell.cancelEdit() to reset the UI back to its original visual state when the editing concludes. In both cases it is important that you also ensure that you call the super method to have the cell perform all duties it must do to enter or exit its editing mode.

Once your cell is in an editing state, the next thing you are most probably interested in is how to commit or cancel the editing that is taking place. This is your responsibility as the cell factory provider. Your cell implementation will know when the editing is over, based on the user input (e.g. when the user presses the Enter or ESC keys on their keyboard). When this happens, it is your responsibility to call Cell.commitEdit(Object) or Cell.cancelEdit(), as appropriate.

When you call Cell.commitEdit(Object) an event is fired to the ListView, which you can observe by adding an EventHandler via setOnEditCommit(javafx.event.EventHandler). Similarly, you can also observe edit events for edit start and edit cancel.

By default the ListView edit commit handler is non-null, with a default handler that attempts to overwrite the property value for the item in the currently-being-edited row. It is able to do this as the Cell.commitEdit(Object) method is passed in the new value, and this is passed along to the edit commit handler via the ListView.EditEvent that is fired. It is simply a matter of calling ListView.EditEvent.getNewValue() to retrieve this value.

It is very important to note that if you call setOnEditCommit(javafx.event.EventHandler) with your own EventHandler, then you will be removing the default handler. Unless you then handle the writeback to the property (or the relevant data source), nothing will happen. You can work around this by using the Node.addEventHandler(javafx.event.EventType, javafx.event.EventHandler) method to add a editCommitEvent() EventType with your desired EventHandler as the second argument. Using this method, you will not replace the default implementation, but you will be notified when an edit commit has occurred.

Hopefully this summary answers some of the commonly asked questions. Fortunately, JavaFX ships with a number of pre-built cell factories that handle all the editing requirements on your behalf. You can find these pre-built cell factories in the javafx.scene.control.cell package.

Property Details

items

public final ObjectProperty<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.

See Also:: getItems(), setItems(ObservableList)

placeholder

public final ObjectProperty<Node> placeholderProperty

This Node is shown to the user when the listview has no content to show. This may be the case because the table model has no data in the first place or that a filter has been applied to the list model, resulting in there being nothing to show the user..

Since:: JavaFX 8.0
See Also:: getPlaceholder(), setPlaceholder(Node)

selectionModel

public final ObjectProperty<MultipleSelectionModel<T>> selectionModelProperty

The SelectionModel provides the API through which it is possible to select single or multiple items within a ListView, as well as inspect which items have been selected by the user. Note that it has a generic type that must match the type of the ListView itself.

See Also:: getSelectionModel(), setSelectionModel(MultipleSelectionModel)

focusModel

public final ObjectProperty<FocusModel<T>> focusModelProperty

The FocusModel provides the API through which it is possible to both get and set the focus on a single item within a ListView. Note that it has a generic type that must match the type of the ListView itself.

See Also:: getFocusModel(), setFocusModel(FocusModel)

orientation

public final ObjectProperty<Orientation> orientationProperty

The orientation of the ListView - this can either be horizontal or vertical.

See Also:: getOrientation(), setOrientation(Orientation)

cellFactory

public final ObjectProperty<Callback<ListView<T>,ListCell<T>>> cellFactoryProperty

Setting a custom cell factory has the effect of deferring all cell creation, allowing for total customization of the cell. Internally, the ListView is responsible for reusing ListCells - all that is necessary is for the custom cell factory to return from this function a ListCell which might be usable for representing any item in the ListView.

Refer to the Cell class documentation for more detail.

See Also:: getCellFactory(), setCellFactory(Callback)

fixedCellSize

public final DoubleProperty fixedCellSizeProperty

Specifies whether this control has cells that are a fixed height (of the specified value). If this value is less than or equal to zero, then all cells are individually sized and positioned. This is a slow operation. Therefore, when performance matters and developers are not dependent on variable cell sizes it is a good idea to set the fixed cell size value. Generally cells are around 24px, so setting a fixed cell size of 24 is likely to result in very little difference in visuals, but a improvement to performance.

To set this property via CSS, use the -fx-fixed-cell-size property. This should not be confused with the -fx-cell-size property. The difference between these two CSS properties is that -fx-cell-size will size all cells to the specified size, but it will not enforce that this is the only size (thus allowing for variable cell sizes, and preventing the performance gains from being possible). Therefore, when performance matters use -fx-fixed-cell-size, instead of -fx-cell-size. If both properties are specified in CSS, -fx-fixed-cell-size takes precedence.

Since:: JavaFX 8.0
See Also:: getFixedCellSize(), setFixedCellSize(double)

editable

public final BooleanProperty editableProperty

Specifies whether this ListView is editable - only if the ListView and the ListCells within it are both editable will a ListCell be able to go into their editing state.

See Also:: isEditable(), setEditable(boolean)

editingIndex

public final ReadOnlyIntegerProperty editingIndexProperty

A property used to represent the index of the item currently being edited in the ListView, if editing is taking place, or -1 if no item is being edited.

It is not possible to set the editing index, instead it is required that you call edit(int).

See Also:: getEditingIndex()

onEditStart

public final ObjectProperty<EventHandler<ListView.EditEvent<T>>> onEditStartProperty

This event handler will be fired when the user successfully initiates editing.

See Also:: getOnEditStart(), setOnEditStart(EventHandler)

onEditCommit

public final ObjectProperty<EventHandler<ListView.EditEvent<T>>> onEditCommitProperty

This property is used when the user performs an action that should result in their editing input being persisted.

The EventHandler in this property should not be called directly - instead call Cell.commitEdit(java.lang.Object) from within your custom ListCell. This will handle firing this event, updating the view, and switching out of the editing state.

See Also:: getOnEditCommit(), setOnEditCommit(EventHandler)

onEditCancel

public final ObjectProperty<EventHandler<ListView.EditEvent<T>>> onEditCancelProperty

This event handler will be fired when the user cancels editing a cell.

See Also:: getOnEditCancel(), setOnEditCancel(EventHandler)

onScrollTo

public ObjectProperty<EventHandler<ScrollToEvent<Integer>>> onScrollToProperty

Called when there's a request to scroll an index into view using scrollTo(int) or scrollTo(Object)

Since:: JavaFX 8.0
See Also:: getOnScrollTo(), setOnScrollTo(EventHandler)

Constructor Details

ListView

public ListView()

Creates a default ListView which will display contents stacked vertically. As no ObservableList is provided in this constructor, an empty ObservableList is created, meaning that it is legal to directly call getItems() if so desired. However, as noted elsewhere, this is not the recommended approach (instead call setItems(javafx.collections.ObservableList)).

Refer to the ListView class documentation for details on the default state of other properties.

ListView

public ListView(ObservableList<T> items)

Creates a default ListView which will stack the contents retrieved from the provided ObservableList vertically.

Attempts to add a listener to the ObservableList, such that all subsequent changes inside the list will be shown to the user.

Refer to the ListView class documentation for details on the default state of other properties.

Parameters:: items - the list of items

Method Details
