    • children

      protected final List<GTreeNode> children()
    • doSetChildrenAndFireEvent

      protected void doSetChildrenAndFireEvent(List<GTreeNode> childList)
      Sets the children of this node to the given list of child nodes and fires the appropriate tree event to kick the tree to update the display. Note: This method must be called from the swing thread because it will notify the underlying JTree.
      Parameters:
      childList - the list of child nodes to assign as children to this node
      See Also:
    • doSetChildren

      protected void doSetChildren(List<GTreeNode> childList)
      Sets the children of this node to the given list of child nodes, but does not notify the tree. This method does not have to be called from the swing thread. It is intended to be used by background threads that want to populate all or part of the tree, but wait until the bulk operations are completed before notifying the tree.
      Parameters:
      childList - the list of child nodes to assign as children to this node
    • doAddNode

      protected void doAddNode(GTreeNode node)
      Adds a node to this node's children. Must be called from the swing thread.
      Parameters:
      node - the node to add as a child to this node
    • doAddNode

      protected void doAddNode(int index, GTreeNode node)
      Adds a node to this node's children at the given index and notifies the tree. Must be called from the swing thread.
      Parameters:
      index - the index at which to add the new node
      node - the node to add as a child to this node
    • doRemoveNode

      protected void doRemoveNode(GTreeNode node)
      Removes the node from this node's children and notifies the tree. Must be called from the swing thread.
      Parameters:
      node - the node to remove
    • doAddNodes

      protected void doAddNodes(List<GTreeNode> nodes)
      Adds the given nodes to this node's children. Must be called from the swing thread.
      Parameters:
      nodes - the nodes to add to the children this node
    • clone

      public GTreeNode clone() throws CloneNotSupportedException
      Creates a clone of this node. The clone should contain a shallow copy of all the node's attributes except that the parent and children are null.
      Overrides:
      clone in class Object
      Returns:
      the clone of this object.
      Throws:
      CloneNotSupportedException - if some implementation prevents itself from being cloned.
    • dispose

      public final boolean isInProgress()
      Returns true if the node is in the process of loading its children. See GTreeSlowLoadingNode
      Returns:
      true if the node is in the process of loading its children.
    • isLoaded

      public boolean isLoaded()
      True if the children for this node have been loaded yet. Some GTree nodes are lazy in that they don't load their children until needed. Nodes that have the IN_PROGRESS node as it child is considered loaded if in the swing thread, otherwise they are considered not loaded.
      Returns:
      true if the children for this node have been loaded.
