# Class Tab

java.lang.Object
javafx.scene.control.Tab

All Implemented Interfaces:
  `Styleable`, `EventTarget`

@DefaultProperty("content") @IDProperty("id") public class Tab extends Object implements EventTarget, Styleable

Tabs are placed within a `TabPane`, where each tab represents a single 'page'.

Tabs can contain any `Node` such as UI controls or groups of nodes added to a layout container.

When the user clicks on a Tab in the TabPane the Tab content becomes visible to the user.

Since:
  JavaFX 2.0

      true if this tab has properties.
    Since:
      JavaFX 2.2

  - ### setUserData

    public void setUserData(Object value)
    Convenience method for setting a single Object property that can be retrieved at a later date. This is functionally equivalent to calling the getProperties().put(Object key, Object value) method. This can later be retrieved by calling `getUserData()`.
    Parameters:
      `value` - The value to be stored - this can later be retrieved by calling `getUserData()`.
    Since:
      JavaFX 2.2

  - ### 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.
    Since:
      JavaFX 2.2

  - ### getStyleClass

    public ObservableList<String> getStyleClass()
    A list of String identifiers which can be used to logically group Nodes, specifically for an external style engine. This variable is analogous to the "class" attribute on an HTML element and, as such, each element of the list is a style class to which this Node belongs.
    Specified by:
      `getStyleClass` in interface `Styleable`
    Returns:
      a list of String identifiers which can be used to logically group Nodes, specifically for an external style engine

  - ### buildEventDispatchChain

    public EventDispatchChain buildEventDispatchChain(EventDispatchChain tail)
    Description copied from interface: `EventTarget`
    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 final <E extends Event> void addEventHandler(EventType<E> eventType, EventHandler<? super E> eventHandler)
    Description copied from interface: `EventTarget`
    Registers an event handler for this target.

    The handler is called when the target receives an `Event` of the specified type during the bubbling phase of event delivery.

    Specified by:
      `addEventHandler` in interface `EventTarget`
    Type Parameters:
      `E` - the event class of the handler
    Parameters:
      `eventType` - the type of the events received by the handler
      `eventHandler` - the event handler

  - ### removeEventHandler

    public final <E extends Event> void removeEventHandler(EventType<E> eventType, EventHandler<? super E> eventHandler)
    Description copied from interface: `EventTarget`
    Unregisters a previously registered event handler from this target.

    Since it is possible to register a single `EventHandler` instance for different event types, the caller needs to specify the event type from which the handler should be unregistered.

    Specified by:
      `removeEventHandler` in interface `EventTarget`
    Type Parameters:
      `E` - the event class of the handler
    Parameters:
      `eventType` - the event type from which to unregister
      `eventHandler` - the event handler

  - ### addEventFilter

    public final <E extends Event> void addEventFilter(EventType<E> eventType, EventHandler<? super E> eventFilter)
    Description copied from interface: `EventTarget`
    Registers an event filter for this target.

    The filter is called when the target receives an `Event` of the specified type during the capturing phase of event delivery.

    Specified by:
      `addEventFilter` in interface `EventTarget`
    Type Parameters:
      `E` - the event class of the filter
    Parameters:
      `eventType` - the type of the events received by the filter
      `eventFilter` - the event filter

  - ### removeEventFilter

    public final <E extends Event> void removeEventFilter(EventType<E> eventType, EventHandler<? super E> eventFilter)
    Description copied from interface: `EventTarget`
    Unregisters a previously registered event filter from this target.

    Since it is possible to register a single `EventHandler` instance for different event types, the caller needs to specify the event type from which the filter should be unregistered.

    Specified by:
      `removeEventFilter` in interface `EventTarget`
    Type Parameters:
      `E` - the event class of the filter
    Parameters:
      `eventType` - the event type from which to unregister
      `eventFilter` - the event filter

  - ### getTypeSelector

    public String getTypeSelector()
    The type of this `Styleable` that is to be used in selector matching. This is analogous to an "element" in HTML. (CSS Type Selector).
    Specified by:
      `getTypeSelector` in interface `Styleable`
    Returns:
      "Tab"
    Since:
      JavaFX 8.0

  - ### getStyleableParent

    public Styleable getStyleableParent()
    Return the parent of this Styleable, or null if there is no parent.
    Specified by:
      `getStyleableParent` in interface `Styleable`
    Returns:
      `getTabPane()`
    Since:
      JavaFX 8.0

  - ### 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
    Since:
      JavaFX 8.0

  - ### getCssMetaData

    public List<CssMetaData<? extends Styleable, ?>> getCssMetaData()
    The CssMetaData of this Styleable. This may be returned as an unmodifiable list.
    Specified by:
      `getCssMetaData` in interface `Styleable`
    Returns:
      the CssMetaData
    Since:
      JavaFX 8.0

  - ### getClassCssMetaData

    public static List<CssMetaData<? extends Styleable, ?>> getClassCssMetaData()
    Gets the `CssMetaData` associated with this class, which may include the `CssMetaData` of its superclasses.
    Returns:
      the `CssMetaData`
