Registers an event filter to this task. Registered event filters get an event before any associated event handlers.

Registers an event handler to this task. Any event filters are first processed, then the specified onFoo event handlers, and finally any event handlers registered by this method. As with other events in the scene graph, if an event is consumed, it will not continue dispatching.

Construct an event dispatch chain for this target.

This is a helper method for easy creation of custom cell factories. The custom cell is automatically created, and it handles rendering of empty cells. The user is only responsible for providing an operation op that renders non-empty cells.

The operation op provides as input the already created custom cell and value of that cell. The value is provided by the cellValueFactory. The value is guaranteed to be non null. The null values are automatically rendered as empty cells by the provided cell object.

Here is an example where value's type is a case class Person that contains two text fields: firstName and lastName.

case class Person(firstName:String, lastName:String)
...

cellFactory = (cell, value) => {
  cell.text = value.firstName + " " + value.lastName
}

Another example where 'value' is of type 'Color' and the cell factory creates a circle representing that color:

cellFactory = (cell, value) => {
  cell.graphic = new Circle {
     fill = value
     radius = 8
  }
}

The cell value factory needs to be set to specify how to populate all cells within a single TableColumn.

class Position(name_ : String, value_ : Int) {
  val name = new StringProperty(this, "name", name_)
  val value = new ObjectProperty[Int](this, "value", value_)
}

val tableView = new TableView[Position](data) {
  columns ++= List(
    new TableColumn[Position, String] {
      text = "Position"
      cellValueFactory = {_.value.name}
      prefWidth = 180
    },
    new TableColumn[Position, Int] {
      text = "Value"
      cellValueFactory = {_.value.value}
      prefWidth = 180
    }
  )
}

This enables support for nested columns, which can be useful to group together related data.

Comparator function used when sorting this TableColumnBase.

This menu will be shown whenever the user right clicks within the header area of this TableColumnBase.

The CssMetaData of this Styleable.

JavaFX object to be wrapped.

Specifies whether this TableColumnBase allows editing.

Verifies if a object is equals to this delegate.

Returns a object that implements scalafx.event.EventHandlerDelegate1.EventHandled.

Registers an event filter. Registered event filters get an event before any associated event handlers.

Example of filtering mouse events

pane.filterEvent(MouseEvent.Any) {
  me: MouseEvent => {
    me.eventType match {
      case MouseEvent.MousePressed => {
        ...
      }
      case MouseEvent.MouseDragged => {
        ...
      }
      case _ => {
        ...
      }
    }
  }
}

or

pane.filterEvent(MouseEvent.Any) { () => println("Some mouse event handled") }

Returns the actual value for a cell from the given item.

Returns the actual value for a cell at a given row index (and which belongs to this TableColumnBase).

The id of this Styleable.

IMPLEMENTATION NOTE: For this method was adopted the name getId instead id to not conflict with its subclasses already have a method with this name which returns a StringProperty.

A string representation of the CSS style associated with this specific Node.

IMPLEMENTATION NOTE: For this method was adopted the name getStyle instead style to not conflict with its subclasses already have a method with this name which returns a StringProperty.

The graphic in the TableColumnBase.

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

Example of handling mouse events

pane.handleEvent(MouseEvent.Any) {
  me: MouseEvent => {
    me.eventType match {
      case MouseEvent.MousePressed => ...
      case MouseEvent.MouseDragged => ...
      case _                       => {}
    }
  }
}

or

pane.handleEvent(MouseEvent.Any) { () => println("Some mouse event handled") }

Tests if this TableColumnBase has properties.

The id of this TableColumnBase.

The maximum width the TableColumnBase is permitted to be resized to.

The minimum width the TableColumnBase is permitted to be resized to.

This read-only property will always refer to the parent of this column, in the situation where nested columns are being used.

The preferred width of the TableColumnBase.

The pseudo-class state of this Styleable.

Unregisters a previously registered event filter from this task. One filter might have been registered for different event types, so the caller needs to specify the particular event type from which to unregister the filter.

Unregisters a previously registered event handler from this task. 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.

Used to indicate whether the width of this column can change.

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

A boolean property to toggle on and off the sortability of this column.

The CSS style string associated to this TableColumnBase.

A list of String identifiers which can be used to logically group Nodes, specifically for an external style engine.

Returns the Node that represents this Styleable object. This method should be overridden in cases where the Styleable is not itself a Node, so that it may optionally return the relevant root node representation of itself. By default this method returns null, which can mean that either the Styleable itself is a Node, or if that is not the case, that the Styleable does not have a node representation available at the time of request.

The parent of this Styleable, or null if there is no parent.

This is the text to show in the header for this column.

The type of this Styleable that is to be used in selector matching.

Returns a previously set Object property, or null if no such property has been set using the setUserData(Any) method.

Toggling this will immediately toggle the visibility of this column, and all children columns.

The width of this column.
