Interface LayoutGroup

All Superinterfaces:
X3DBoundedObject, X3DChildNode, X3DGroupingNode, X3DNode
All Known Implementing Classes:
LayoutGroupObject

public interface LayoutGroup
extends X3DNode, X3DGroupingNode
LayoutGroup is a Grouping node that can contain most nodes, whose children are related by a common layout within a parent layout.

X3D node tooltip: (X3D version 3.2 or later) [X3DGroupingNode] LayoutGroup is a Grouping node that can contain most nodes, whose children are related by a common layout within a parent layout. The layout field contains an X3DLayoutNode node that provides the information required to locate and size the layout region of the LayoutGroup node relative to its parent’s layout region. LayoutGroup content is clipped by the specified viewport node.
  • Hint: The origin of the node is always in the center of its layout region. Thus, children (with the exception of LayoutGroup) are specified in a coordinate system whose origin is located at the center of the rectangle and can be transformed from that location.
  • Warning: a LayoutGroup can only be a child of a LayoutLayer node or another LayoutGroup node.
  • Hint: insert a Shape node before adding geometry or Appearance.
  • Hint: LayoutGroup does not directly have any pixel-dependent concepts. However, it can contain a Layout node that does have pixel-specific options.

Package hint: This interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).

      Tooltip: Bounding box center accompanies bboxSize and provides an optional hint for bounding box position offset from origin of local coordinate system.
      Specified by:
      getBboxCenter in interface X3DBoundedObject
      Specified by:
      getBboxCenter in interface X3DGroupingNode
      Returns:
      value of bboxCenter field
    • setBboxCenter

      LayoutGroup setBboxCenter​(float[] newValue)

      Tooltip: Bounding box center accompanies bboxSize and provides an optional hint for bounding box position offset from origin of local coordinate system.
      Specified by:
      setBboxCenter in interface X3DBoundedObject
      Specified by:
      setBboxCenter in interface X3DGroupingNode
      Parameters:
      newValue - is new value for the bboxCenter field.

      Specified by:
      getBboxSize in interface X3DBoundedObject
      Specified by:
      getBboxSize in interface X3DGroupingNode

      • Hint: inputOnly MFNode addChildren field can append new X3DChildNode nodes via a ROUTE connection, duplicate input nodes (i.e. matching DEF, USE values) are ignored.
