Overview

Base class for scene graph nodes. A scene graph is a set of tree data structures where every item has zero or one parent, and each item is either a "leaf" with zero sub-items or a "branch" with zero or more sub-items.

Each item in the scene graph is called a Node. Branch nodes are either of type Group or of type CustomNode, or subclasses thereof. Leaf nodes are classes such as javafx.scene.shape.Rectangle, javafx.scene.text.Text, javafx.scene.image.ImageView, javafx.scene.media.MediaView, or other such leaf nodes. Only a single node within each scene graph tree will have no parent, which is often referred to as the "root" node.

There may be several trees in the scene graph. Some trees may be part of a Scene, in which case they are eligible to be displayed. Other trees might not part of any Scene.

A node may occur at most once anywhere in the scene graph. Specifically, a node must appear no more than once in all of the following: in the content sequence of a Group, in the content sequence of a Scene, as the clip of a Node, or as the return value of the create function of a CustomNode subclass.

The scene graph must not have cycles. A cycle would exist if a node is a parent of itself in the tree, considering the Group content sequence, Node clip, and CustomNode relationships mentioned above.

If code attempts to modify the scene graph in any way that violates the above rules, the modification attempt is ignored and the scene graph is restored to its previous state.

It is possible to rearrange the structure of the scene graph, for example, to move a subtree from one location in the scene graph to another. In order to do this, one must first remove the subtree from its old location before inserting it at the new location. Note that there is no way to change the "child" of a CustomNode. Once a node has been returned from the CustomNode create function, that node cannot be reused elsewhere in the scene graph.

String ID

Each node in the scene graph can be given a unique id. This id is much like the "id" attribute of an HTML tag in that it is up to the designer and developer to ensure that the id is unique within the scene graph. A convenience function called lookup(String) can be used to find a node with a unique id within the scene graph, or within a subtree of the scene graph.

Coordinate System

The Node class defines a traditional computer graphics "local" coordinate system in which the x axis increases to the right and the y axis increases downwards. The concrete node classes for shapes provide variables for configuring the geometry and location of the shape within this local coordinate space. For example, javafx.scene.shape.Rectangle provides x, y, width, height variables while javafx.scene.shape.Circle provides centerX, centerY, and radius.

Transformations

Any Node can have transformations applied to it. These include translation, rotation, scaling, or shearing transformations.

A translation transformation is one which shifts the origin of the node's coordinate space along either the x or y axis. For example, if you create a javafx.scene.shape.Rectangle which is drawn at the origin (x=0, y=0) and has a width of 100 and a height of 50, and then apply a javafx.scene.transform.Translate with a shift of 10 along the x axis (x=10), then the rectangle will appear drawn at (x=10, y=0) and remain 100 points wide and 50 tall. Note that the origin was shifted, not the x variable of the rectangle.

A rotation transformation is one which rotates the coordinate space of the node about a specified "pivot" point, causing the node to appear rotated. For example, if you create a javafx.scene.shape.Rectangle which is drawn at the origin (x=0, y=0) and has a width of 100 and height of 30 and you apply a javafx.scene.transform.Rotate with a 90 degree rotation (angle=90) and a pivot at the origin (pivotX=0, pivotY=0), then the rectangle will be drawn as if its x and y were zero but its height was 100 and its width -30. That is, it is as if a pin is being stuck at the top left corner and the rectangle is rotating 90 degrees clockwise around that pin. If the pivot point is instead placed in the center of the rectangle (at point x=50, y=15) then the rectangle will instead appear to rotate about its center.

Note that as with all transformations, the x, y, width, and height variables of the rectangle (which remain relative to the local coordinate space) have not changed, but rather the transformation alters the entire coordinate space of the rectangle.

A scaling transformation causes a node to either appear larger or smaller depending on the scaling factor. Scaling alters the coordinate space of the node such that each unit of distance along the axis in local coordinates is multipled by the scale factor. As with rotation transformations, scaling transformations are applied about a "pivot" point. You can think of this as the point in the Node around which you "zoom". For example, if you create a javafx.scene.shape.Rectangle with a strokeWidth of 5, and a width and height of 50, and you apply a javafx.scene.transform.Scale with scale factors (x=2.0, y=2.0) and a pivot at the origin (pivotX=0, pivotY=0), the entire rectangle (including the stroke) will double in size, growing to the right and downwards from the origin.

A shearing transformation, sometimes called a skew, effectively rotates one axis so that the x and y axes are no longer perpendicular.

Multiple transformations may be applied to a node by specifying an ordered chain of transforms. The order in which the transforms are applied is defined by the sequence specified in the transforms variable.

Bounding Rectangles

Since every Node has transformations, every Node's geometric bounding rectangle that can be described differently depending on whether transformations are accounted for or not.

At the simplest, Node's have a read-only boundsInLocal variable which specifies the bounding rectangle of the Node in untransformed local coordinates. boundsInLocal includes the Node's shape geometry, including any space required for a non-zero stroke that may fall outside the local position/size variables, its clip and effect variables (if set).

The layoutBounds variable defines the rectangular bounds of a Node that should be used as the basis for layout calculations. By default this will be equal to boundsInLocal plus transforms set in the transforms variable but does NOT include transforms set by the explicit translateX, translateY, scaleX, scaleY, and rotate variables.

Finally, each Node also has a read-only boundsInParent variable which specifies the bounding rectangle of the Node after all transformations have been applied, including those set in transforms, translateX, translateY, scaleX, scaleY, and rotate. It is called "boundsInParent" because the rectangle will be defined in terms of the parent Node's coordinate system.

public-readboundsInLocalBounds

The rectangular bounds of this Node in the Node's untransformed local coordinate space.

The rectangular bounds of this Node in the Node's untransformed local coordinate space. For nodes that extend javafx.scene.shape.Shape, the local bounds will also include space required for a non-zero stroke that may fall outside the shape's geometry that is defined by position and size attributes. The local bounds will also include any clipping set with clip as well as effects set with effect.

Note that this method does not take the node's visibility into account; the test is based on the geometry of this Node only.

This variable will always be a non-null value.

Note that boundsInLocal is automatically recomputed whenever the geometry of a node changes. For this reason, it is an error to bind any of these values in a node to an expression that depends upon this variable. For example, the "x" or "y" variables of a shape should never be bound to boundsInLocal for the purpose of positioning the node.

Profile: common

 
public-readboundsInParentBounds

The rectangular bounds of this Node which include its transforms.

The rectangular bounds of this Node which include its transforms. boundsInParent is calculated by taking its local bounds (defined by boundsInLocal) and applying the transform created by setting the following additional variables:

  1. transforms[] sequence
  2. layoutX, layoutY
  3. translateX, translateY
  4. scaleX, scaleY
  5. rotate

The resulting bounds will be conceptually in the coordinate space of the Node's parent, however the node need not have a parent to calculate these bounds.

Note that this method does not take the node's visibility into account; the test is based on the geometry of this Node only.

This variable will always be a non-null value.

Note that boundsInParent is automatically recomputed whenever the geometry of a node changes, or when any of the following change: the transforms sequence, the translateX, translateY, layoutX, layoutY, scaleX, scaleY, or rotate variable. For this reason, it is an error to bind any of these values in a node to an expression that depends upon this variable. For example, the "x" or "y" variables of a shape, or translateX, translateY should never be bound to boundsInParent for the purpose of positioning the node.

Profile: common

 
publiccacheBooleanfalse

A performance hint to the system to indicate that this Node should be cached as a bitmap.

A performance hint to the system to indicate that this Node should be cached as a bitmap. Rendering a bitmap representation of a node will be faster than rendering primitives in many cases, especially in the case of primitives with effects applied (such as a blur). However, it also increases memory usage. This hint indicates whether that trade-off (increased memory usage for increased performance) is worthwhile. Also note that on some platforms such as GPU accelerated platforms there is little benefit to caching Nodes as bitmaps when blurs and other effects are used since they are very fast to render on the GPU.

false

Profile: common

 
publicclipNodenull

Specifies a Node to use to define the the clipping shape for this Node.

Specifies a Node to use to define the the clipping shape for this Node. This clipping Node is not a child of this Node in the scene graph sense. Rather, it is used to define the clip for this Node.

For example, you can use an javafx.scene.image.ImageView Node as a mask to represent the Clip. Or you could use one of the geometric shape Nodes such as javafx.scene.shape.Rectangle or javafx.scene.shape.Circle. Or you could use a javafx.scene.text.Text node to represent the Clip.

See the class documentation for Node for scene graph structure restrictions on setting the clip. If these restrictions are violated by a change to the clip variable, the change is ignored and the previous value of the clip variable is restored.

publiccursorCursornull

Defines the mouse cursor for this Node and subnodes.

Defines the mouse cursor for this Node and subnodes. If null, then the cursor of the first parent node with a non-null cursor will be used. If no Node in the scene graph defines a cursor, then the cursor of the Scene will be used.

null

Profile: common conditional cursor

 
publicdisableBooleanfalse

Sets the individual disabled state of this Node.

Sets the individual disabled state of this Node. Setting disable to true will cause this Node and any subnodes to become disabled. This variable should be used only to set the disabled state of a Node. For querying the disabled state of a Node, the disabled variable should instead be used, since it is possible that a Node was disabled as a result of an ancestor being disabled even if the individual disable state on this Node is false.

false

Profile: common

 
public-readdisabledBooleanfalse

Indicates whether or not this Node is disabled.

Indicates whether or not this Node is disabled. A Node will become disabled if disable is set to true on either itself or one of its ancestors in the scene graph.

A disabled Node should render itself differently to indicate its disabled state to the user. Such disabled rendering is dependent on the implementation of the Node. The shape classes contained in javafx.scene.shape do not implement such rendering by default, therefore applications using shapes for handling input must implement appropriate disabled rendering themselves. The user-interface controls defined in javafx.scene.control will implement disabled-sensitive rendering, however.

A disabled Node does not receive mouse or key events.

false

Profile: common

 
publiceffectEffectnull

Specifies an effect to apply to this Node.

public-read protectedfocusedBooleansubclasssubclassfalse

Indicates whether this Node is the current input focus owner.

Indicates whether this Node is the current input focus owner. Only one node at a time may be the current focus owner.

false

Profile: common

 
publicfocusTraversableBooleanfase

Specifies whether this Node should be a part of focus traversal cycle.

Specifies whether this Node should be a part of focus traversal cycle. When this property is true focus can be moved to this Node and from this Node using regular focus traversal keys. On a desktop such keys are usually TAB for moving focus forward and SHIFT+TAB for moving focus backward. By default the first focus traversable and focusable Node added to a Scene is to receive focus by default.

fase

Profile: common

 
public-read protectedhoverBooleansubclasssubclassfalse

Whether or not this Node is being hovered over.

Whether or not this Node is being hovered over. Typically this is due to the mouse being over the node, though it could be due to a pen hovering on a graphics tablet or other form of input.

NOTE: the current implementation of hover relies on mouse enter and exit events to determine whether this Node is in the hover state; this means that this feature is currently supported only on systems that have a mouse. Future implementations may provide alternative means of supporting hover.

false

Profile: common

 
publicidStringempty string

The id of this Node.

The id of this Node. This simple string identifier is useful for finding a specific Node within the scene graph. While the id of a Node should be unique within the scene graph, this uniqueness is not enforced. This is much like the "id" attribute of an HTML element.

empty string

Profile: common

 
public-read protectedlayoutBoundsBoundssubclasssubclass

The rectangular bounds that should be used in calculations for both manual and automatic layout of this Node.

The rectangular bounds that should be used in calculations for both manual and automatic layout of this Node. By default, layoutBounds will be equal to the geometric bounds of the node and does not include the effect, clip, or transforms.

Note that the layoutX, layoutY, translateX, and translateY variables are not included in the layoutBounds. This is important because layout code must first determine the current size and location of the Node (using layoutBounds) and then set layoutX and layoutY to adjust the translation of the Node so that it will have the desired layout position.

layoutBounds is automatically recomputed whenever the geometry of a node changes. For this reason, it is an error to bind any of these values in a node to an expression that depends upon this variable. For example, the "x" or "y" variables of a shape should never be bound to layoutBounds for the purpose of positioning the node.

Profile: common

 
publiclayoutInfoLayoutInfoBase

Hook for node-specific layout information used by layout containers.

Hook for node-specific layout information used by layout containers. If the node is not a child of a container which supports layout info, this variable will be ignored.

Note that layoutInfo object literals may be shared across nodes, which means altering the vars in layoutInfo will affect all such nodes.

 
publiclayoutXNumber0

Defines the X coordinate of the translation that is added to the transformed coordinates of this Node for the purpose of layout.

Defines the X coordinate of the translation that is added to the transformed coordinates of this Node for the purpose of layout. Containers or Groups performing layout will set this variable relative to layoutBounds.minX in order to position the node at the desired layout location.

For example, if child should have a final location of finalX:

     child.layoutX = finalX - child.layoutBounds.minX;
 

0

Profile: common

 
publiclayoutYNumber0

Defines the Y coordinate of the translation that is added to the transformed coordinates of this Node for the purpose of layout.

Defines the Y coordinate of the translation that is added to the transformed coordinates of this Node for the purpose of layout. Containers or Groups performing layout will set this variable relative to layoutBounds.minY in order to position the node at the desired layout location.

For example, if child should have a final location of finalY:

     child.layoutY = finalY - child.layoutBounds.minY;

publiconMouseEnteredfunction(:MouseEvent):Void

Defines a function to be called when the mouse enters this Node.

publiconMouseExitedfunction(:MouseEvent):Void

Defines a function to be called when the mouse exits this Node.

publiconMouseMovedfunction(:MouseEvent):Void

Defines a function to be called when mouse cursor moves within this Node but no buttons have been pushed.

publiconMousePressedfunction(:MouseEvent):Void

Defines a function to be called when a mouse button has been pressed on this Node.

publiconMouseReleasedfunction(:MouseEvent):Void

Defines a function to be called when a mouse button has been released on this Node.

publiconMouseWheelMovedfunction(:MouseEvent):Void

Defines a function to be called when the mouse scroll wheel has moved.

publicopacityNumber1.0

Specifies how opaque (that is, solid) the Node appears.

Specifies how opaque (that is, solid) the Node appears. A Node with 0% opacity is fully translucent. That is, while it is still visible and rendered, you generally won't be able to see it. The exception to this rule is when the ZNode is combined with a blending mode and blend effect in which case a translucent Node may still have an impact in rendering. An opacity of 50% will render the node as being 50% transparent.

A visible node with any opacity setting still receives mouse events and can receive keyboard focus. For example, if you want to have a large invisible rectangle overlay all Nodes in the scene graph in order to intercept mouse events but not be visible to the user, you could create a large Rectangle that had an opacity of 0%.

Opacity is specified as a value between 0 and 1. Values less than 0 or greater than 1 are clipped to 0 and 1 respectively.

On some platforms ImageView might not support opacity variable.

public-read protectedpressedBooleansubclasssubclassfalse

publicrotateNumber0.0

Defines the angle of rotation about the Node's center, measured in degrees.

Defines the angle of rotation about the Node's center, measured in degrees. This is used to rotate the Node.

This rotation factor is not included in layoutBounds by default, which makes it ideal for rotating the entire node after all effects and transforms have been taken into account.

The pivot point about which the rotation occurs is the center of the untransformed layoutBounds.

Note that because the pivot point is computed as the center of this Node's layout bounds, any change to the layout bounds will cause the pivot point to change, which can move the object. For a leaf node, any change to the geometry will cause the layout bounds to change. For a group node, any change to any of its children, including a change in a child's geometry, clip, effect, position, orientation, or scale, will cause the group's layout bounds to change. If this movement of the pivot point is not desired, applications should instead use the Node's transforms[] sequence, and add a javafx.scene.transform.Rotate transform, which has a user-specifiable pivot point.

publicscaleXNumber1.0

protected impl_boundsChanged() : Void

Invoked by anything which may cause the boundsInLocal to change.

Invoked by anything which may cause the boundsInLocal to change. We do it this way to avoid actually having to recompute the bounds (ie, if I put an on replace trigger on boundsInLocal, then it would force the recomputation of bounds in every case even in situations where we don't need to be computing bounds. This way we don't do that).

Invoking this function will cause the entire chain of parent nodes to this node to be notified that their child bounds have changed, which may cause them to revalidate their bounds if somebody is listening to their bounds, or in the simplest case will just walk up the tree and notify that bounds have changed.
