Class TableColumnBase<S,​T>

java.lang.Object
javafx.scene.control.TableColumnBase<S,​T>
Type Parameters:
S - The type of the UI control (e.g. the type of the 'row').
T - The type of the content in all cells in this table column.
All Implemented Interfaces:
Styleable, EventTarget
Direct Known Subclasses:
TableColumn, TreeTableColumn
@IDProperty("id")
public abstract class TableColumnBase<S,​T>
extends Object
implements EventTarget, Styleable
Table-like controls (such as TableView and TreeTableView) are made up of zero or more instances of a concrete TableColumnBase subclass (TableColumn and TreeTableColumn, respectively). Each table column in a table is responsible for displaying (and editing) the contents of that column. As well as being responsible for displaying and editing data for a single column, a table column also contains the necessary properties to: When instantiating a concrete subclass of TableColumnBase, perhaps the two most important properties to set are the column text (what to show in the column header area), and the column cell value factory (which is used to populate individual cells in the column). Refer to the class documentation for TableColumn and TreeTableColumn for more information.

JavaFX 8.0

  • Property Details

    • text

      public final StringProperty textProperty
      This is the text to show in the header for this column.
      See Also:
      getText(), setText(String)

    • visible

      public final BooleanProperty visibleProperty
      Toggling this will immediately toggle the visibility of this column, and all children columns.
      See Also:
      isVisible(), setVisible(boolean)

    • parentColumn

      public final ReadOnlyObjectProperty<TableColumnBase<S,​?>> parentColumnProperty
      This read-only property will always refer to the parent of this column, in the situation where nested columns are being used.

      In the currently existing subclasses, to create a nested column is simply a matter of placing the relevant TableColumnBase instances inside the columns ObservableList (for example, see TableColumn.getColumns() and TreeTableColumn.getColumns().

      See Also:
      getParentColumn()

    • contextMenu

      public final ObjectProperty<ContextMenu> contextMenuProperty
      This menu will be shown whenever the user right clicks within the header area of this TableColumnBase.
      See Also:
      getContextMenu(), setContextMenu(ContextMenu)

    • id

      public final StringProperty idProperty
      The id of this TableColumnBase. This simple string identifier is useful for finding a specific TableColumnBase within a UI control that uses TableColumnBase instances. The default value is null.
      Default value:
      null
      See Also:
      getId(), setId(String)

    • style

      public final StringProperty styleProperty
      A string representation of the CSS style associated with this TableColumnBase instance. This is analogous to the "style" attribute of an HTML element. Note that, like the HTML style attribute, this variable contains style properties and values and not the selector portion of a style rule.

      Parsing this style might not be supported on some limited platforms. It is recommended to use a standalone CSS file instead.

      Default value:
      empty string
      See Also:
      getStyle(), setStyle(String)

    • graphic

      public final ObjectProperty<Node> graphicProperty

      The graphic to show in the table column to allow the user to indicate graphically what is in the column.

      See Also:
      getGraphic(), setGraphic(Node)

    • sortNode

      public final ObjectProperty<Node> sortNodeProperty

      The node to use as the "sort arrow", shown to the user in situations where the table column is part of the sort order. It may be the only item in the sort order, or it may be a secondary, tertiary, or latter sort item, and the node should reflect this visually. This is only used in the case of the table column being in the sort order (refer to, for example, TableView.getSortOrder() and TreeTableView.getSortOrder()). If not specified, the table column skin implementation is responsible for providing a default sort node.

      The sort node is commonly seen represented as a triangle that rotates on screen to indicate whether the table column is part of the sort order, and if so, whether the sort is ascending or descending, and what position in the sort order it is in.

      See Also:
      getSortNode(), setSortNode(Node)

    • width

      public final ReadOnlyDoubleProperty widthProperty
      The width of this column. Modifying this will result in the column width adjusting visually. It is recommended to not bind this property to an external property, as that will result in the column width not being adjustable by the user through dragging the left and right borders of column headers.
      See Also:
      getWidth()

    • minWidth

      public final DoubleProperty minWidthProperty
      The minimum width the table column is permitted to be resized to.
      See Also:
      getMinWidth(), setMinWidth(double)

    • prefWidth

      public final DoubleProperty prefWidthProperty

      See Also:
      getMaxWidth(), setMaxWidth(double)

    • resizable

      public final BooleanProperty resizableProperty
      Used to indicate whether the width of this column can change. It is up to the resizing policy to enforce this however.
      See Also:
      isResizable(), setResizable(boolean)

    • sortable

      public final BooleanProperty sortableProperty

      A boolean property to toggle on and off the 'sortability' of this column. When this property is true, this column can be included in sort operations. If this property is false, it will not be included in sort operations, even if it is contained within the sort order list of the underlying UI control (e.g. TableView.getSortOrder() or TreeTableView.getSortOrder()).

      For example, iIf a TableColumn instance is contained within the TableView sortOrder ObservableList, and its sortable property toggles state, it will force the TableView to perform a sort, as it is likely the view will need updating.

      See Also:
      isSortable(), setSortable(boolean)

    • reorderable

      public final BooleanProperty reorderableProperty
      A boolean property to toggle on and off the 'reorderability' of this column (with drag and drop - reordering by modifying the appropriate columns list is always allowed).

      value - The value to be stored - this can later be retrieved by calling getUserData().

    • getUserData

      public Object getUserData()
      Returns a previously set Object property, or null if no such property has been set using the setUserData(java.lang.Object) method.
      Returns:
      The Object that was previously set, or null if no property has been set or if null was set.

    • getColumns

      public abstract ObservableList<? extends TableColumnBase<S,​?>> getColumns()
      This enables support for nested columns, which can be useful to group together related data. For example, we may have a 'Name' column with two nested columns for 'First' and 'Last' names.

      This has no impact on the table as such - all column indices point to the leaf columns only, and it isn't possible to sort using the parent column, just the leaf columns. In other words, this is purely a visual feature.

      Returns:
      An ObservableList containing TableColumnBase instances (or subclasses) that are the children of this TableColumnBase. If these children TableColumnBase instances are set as visible, they will appear beneath this table column.

    • getCellData

      public final T getCellData​(int index)
      Returns the actual value for a cell at a given row index (and which belongs to this table column).
      Parameters:
      index - The row index for which the data is required.
      Returns:
      The data that belongs to the cell at the intersection of the given row index and the table column that this method is called on.

    • getCellData

      public final T getCellData​(S item)
      Returns the actual value for a cell from the given item.
      Parameters:
      item - The item from which a value of type T should be extracted.
      Returns:
      The data that should be used in a specific cell in this column, based on the item passed in as an argument.

    • getCellObservableValue

      public abstract ObservableValue<T> getCellObservableValue​(int index)
      Attempts to return an ObservableValue<T> for the item in the given index (which is of type S). In other words, this method expects to receive an integer value that is greater than or equal to zero, and less than the size of the underlying data model. If the index is valid, this method will return an ObservableValue<T> for this specific column.

      This is achieved by calling the cell value factory, and returning whatever it returns when passed a CellDataFeatures (see, for example, the CellDataFeatures classes belonging to TableColumn and TreeTableColumn for more information).

      Parameters:
      index - The index of the item (of type S) for which an ObservableValue<T> is sought.
      Returns:
      An ObservableValue<T> for this specific table column.

    • getCellObservableValue

      public abstract ObservableValue<T> getCellObservableValue​(S item)
      Attempts to return an ObservableValue<T> for the given item (which is of type S). In other words, this method expects to receive an object from the underlying data model for the entire 'row' in the table, and it must return an ObservableValue<T> for the value in this specific column.

      This is achieved by calling the cell value factory, and returning whatever it returns when passed a CellDataFeatures (see, for example, the CellDataFeatures classes belonging to TableColumn and TreeTableColumn for more information).

      Parameters:
      item - The item (of type S) for which an ObservableValue<T> is sought.
      Returns:
      An ObservableValue<T> for this specific table column.

    • buildEventDispatchChain

      public EventDispatchChain buildEventDispatchChain​(EventDispatchChain tail)
      Construct an event dispatch chain for this target. The event dispatch chain contains event dispatchers which might be interested in processing of events targeted at this EventTarget. This event target is not automatically added to the chain, so if it wants to process events, it needs to add an EventDispatcher for itself to the chain.

      In the case the event target is part of some hierarchy, the chain for it is usually built from event dispatchers collected from the root of the hierarchy to the event target.

      The event dispatch chain is constructed by modifications to the provided initial event dispatch chain. The returned chain should have the initial chain at its end so the dispatchers should be prepended to the initial chain.

      The caller shouldn't assume that the initial chain remains unchanged nor that the returned value will reference a different chain.

      Specified by:
      buildEventDispatchChain in interface EventTarget
      Parameters:
      tail - the initial chain to build from
      Returns:
      the resulting event dispatch chain for this target

    • addEventHandler

      public <E extends Event> void addEventHandler​(EventType<E> eventType, EventHandler<E> eventHandler)
      Registers an event handler to this table column. The TableColumnBase class allows registration of listeners which will be notified when editing occurs. Note however that TableColumnBase is not a Node, and therefore no visual events will be fired on it.
      Type Parameters:
      E - The type of event
      Parameters:
      eventType - the type of the events to receive by the handler
      eventHandler - the handler to register
      Throws:
      NullPointerException - if the event type or handler is null

    • removeEventHandler

      public <E extends Event> void removeEventHandler​(EventType<E> eventType, EventHandler<E> eventHandler)
      Unregisters a previously registered event handler from this table column. One handler might have been registered for different event types, so the caller needs to specify the particular event type from which to unregister the handler.
      Type Parameters:
      E - The type of event
      Parameters:
      eventType - the event type from which to unregister
      eventHandler - the handler to unregister
      Throws:
      NullPointerException - if the event type or handler is null

    • getPseudoClassStates

      public final ObservableSet<PseudoClass> getPseudoClassStates()
      Return the pseudo-class state of this Styleable. CSS assumes this set is read-only.
      Specified by:
      getPseudoClassStates in interface Styleable
      Returns:
      the pseudo-class state
