. We can immediately
* set such a list directly in to the TableView, as such:}
*
*
* {@code
* ObservableList teamMembers = getTeamMembers();
* table.setItems(teamMembers);}
*
* With the items set as such, TableView will automatically update whenever
* the teamMembers list changes. If the items list is available
* before the TableView is instantiated, it is possible to pass it directly into
* the constructor.
*
*
At this point we now have a TableView hooked up to observe the
* teamMembers observableList. The missing ingredient
* now is the means of splitting out the data contained within the model and
* representing it in one or more {@link TableColumn TableColumn} instances. To
* create a two-column TableView to show the firstName and lastName properties,
* we extend the last code sample as follows:
*
*
* {@code
* ObservableList teamMembers = ...;
* table.setItems(teamMembers);
*
* TableColumn firstNameCol = new TableColumn("First Name");
* firstNameCol.setCellValueFactory(new PropertyValueFactory("firstName"));
* TableColumn lastNameCol = new TableColumn("Last Name");
* lastNameCol.setCellValueFactory(new PropertyValueFactory("lastName"));
*
* table.getColumns().setAll(firstNameCol, lastNameCol);}
*
* With the code shown above we have fully defined the minimum properties
* required to create a TableView instance. Running this code (assuming the
* people ObservableList is appropriately created) will result in a TableView being
* shown with two columns for firstName and lastName. Any other properties of the
* Person class will not be shown, as no TableColumns are defined.
*
*
TableView support for classes that don't contain properties
*
* The code shown above is the shortest possible code for creating a TableView
* when the domain objects are designed with JavaFX properties in mind
* (additionally, {@link javafx.scene.control.cell.PropertyValueFactory} supports
* normal JavaBean properties too, although there is a caveat to this, so refer
* to the class documentation for more information). When this is not the case,
* it is necessary to provide a custom cell value factory. More information
* about cell value factories can be found in the {@link TableColumn} API
* documentation, but briefly, here is how a TableColumn could be specified:
*
*
* {@code
* firstNameCol.setCellValueFactory(new Callback, ObservableValue>() {
* public ObservableValue call(CellDataFeatures p) {
* // p.getValue() returns the Person instance for a particular TableView row
* return p.getValue().firstNameProperty();
* }
* });
* }}
*
* TableView Selection / Focus APIs
* To track selection and focus, it is necessary to become familiar with the
* {@link SelectionModel} and {@link FocusModel} classes. A TableView has at most
* one instance of each of these classes, available from
* {@link #selectionModelProperty() selectionModel} and
* {@link #focusModelProperty() 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 {@link SelectionModel} used when instantiating a TableView is
* an implementation of the {@link MultipleSelectionModel} abstract class.
* However, as noted in the API documentation for
* the {@link MultipleSelectionModel#selectionModeProperty() selectionMode}
* property, the default value is {@link SelectionMode#SINGLE}. To enable
* multiple selection in a default TableView instance, it is therefore necessary
* to do the following:
*
*
* {@code
* tableView.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);}
*
* Customizing TableView Visuals
* The visuals of the TableView can be entirely customized by replacing the
* default {@link #rowFactoryProperty() row factory}. A row factory is used to
* generate {@link TableRow} instances, which are used to represent an entire
* row in the TableView.
*
*
In many cases, this is not what is desired however, as it is more commonly
* the case that cells be customized on a per-column basis, not a per-row basis.
* It is therefore important to note that a {@link TableRow} is not a
* {@link TableCell}. A {@link TableRow} is simply a container for zero or more
* {@link TableCell}, and in most circumstances it is more likely that you'll
* want to create custom TableCells, rather than TableRows. The primary use case
* for creating custom TableRow instances would most probably be to introduce
* some form of column spanning support.
*
*
You can create custom {@link TableCell} instances per column by assigning
* the appropriate function to the TableColumn
* {@link TableColumn#cellFactoryProperty() cell factory} property.
*
*
See the {@link Cell} class documentation for a more complete
* description of how to write custom Cells.
*
*
Sorting
* Prior to JavaFX 8.0, the TableView control would treat the
* {@link #getItems() items} list as the view model, meaning that any changes to
* the list would be immediately reflected visually. TableView would also modify
* the order of this list directly when a user initiated a sort. This meant that
* (again, prior to JavaFX 8.0) it was not possible to have the TableView return
* to an unsorted state (after iterating through ascending and descending
* orders).
*
* Starting with JavaFX 8.0 (and the introduction of {@link SortedList}), it
* is now possible to have the collection return to the unsorted state when
* there are no columns as part of the TableView
* {@link #getSortOrder() sort order}. To do this, you must create a SortedList
* instance, and bind its
* {@link javafx.collections.transformation.SortedList#comparatorProperty() comparator}
* property to the TableView {@link #comparatorProperty() comparator} property,
* list so:
*
*
* {@code
* // create a SortedList based on the provided ObservableList
* SortedList sortedList = new SortedList(FXCollections.observableArrayList(2, 1, 3));
*
* // create a TableView with the sorted list set as the items it will show
* final TableView tableView = new TableView<>(sortedList);
*
* // bind the sortedList comparator to the TableView comparator
* sortedList.comparatorProperty().bind(tableView.comparatorProperty());
*
* // Don't forget to define columns!
* }
*
* 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
* {@link Cell} implementation being used. For TableView, it is highly
* recommended that editing be
* {@link javafx.scene.control.TableColumn#cellFactoryProperty() per-TableColumn},
* rather than {@link #rowFactoryProperty() per row}, as more often than not
* you want users to edit each column value differently, and this approach allows
* for editors specific to each column. It is your choice whether the cell is
* permanently in an editing state (e.g. this is common for {@link 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 {@link javafx.scene.control.Cell#startEdit()} method, and
* update the cell {@link javafx.scene.control.Cell#textProperty() text} and
* {@link javafx.scene.control.Cell#graphicProperty() graphic} properties as
* appropriate (e.g. set the text to null and set the graphic to be a
* {@link TextField}). Additionally, you should also override
* {@link 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 {@link Cell#commitEdit(Object)} or
* {@link Cell#cancelEdit()}, as appropriate.
*
* When you call {@link Cell#commitEdit(Object)} an event is fired to the
* TableView, which you can observe by adding an {@link EventHandler} via
* {@link TableColumn#setOnEditCommit(javafx.event.EventHandler)}. Similarly,
* you can also observe edit events for
* {@link TableColumn#setOnEditStart(javafx.event.EventHandler) edit start}
* and {@link TableColumn#setOnEditCancel(javafx.event.EventHandler) edit cancel}.
*
* By default the TableColumn 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
* {@link Cell#commitEdit(Object)} method is passed in the new value, and this
* is passed along to the edit commit handler via the
* {@link javafx.scene.control.TableColumn.CellEditEvent CellEditEvent} that is
* fired. It is simply a matter of calling
* {@link javafx.scene.control.TableColumn.CellEditEvent#getNewValue()} to
* retrieve this value.
*
*
It is very important to note that if you call
* {@link TableColumn#setOnEditCommit(javafx.event.EventHandler)} with your own
* {@link 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
* {@link TableColumn#addEventHandler(javafx.event.EventType, javafx.event.EventHandler)}
* method to add a {@link TableColumn#EDIT_COMMIT_EVENT} {@link EventType} with
* your desired {@link 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.
