```
    Construct a new CellBrowser.TreeNodeImpl.
    
    Parameters:
    nodeInfo - the nodeInfo for the children nodes
    value - the value of the node
    display - the display associated with the node
    widget - the widget that wraps the display
- Method Detail
  - getChildCount
```
public int getChildCount()
```
    Description copied from interface: TreeNode
    
    Get the number of children of the node.
    
    Specified by:
    
    getChildCount in interface TreeNode
    
    Returns:
    the child count
  - getChildValue
```
public C getChildValue(int index)
```
    Description copied from interface: TreeNode
    
    Get the value associated with a child node.
    
    Specified by:
    
    getChildValue in interface TreeNode
    
    Parameters:
    index - the child index
    
    Returns:
    the value
  - getIndex
```
public int getIndex()
```
    Description copied from interface: TreeNode
    
    Get the index of the current node relative to its parent.
    
    Specified by:
    
    getIndex in interface TreeNode
    
    Returns:
    the index of the current node
  - getParent
```
public CellBrowser.TreeNodeImpl<?> getParent()
```
    Description copied from interface: TreeNode
    
    Get the parent node of this node.
    
    Specified by:
    
    getParent in interface TreeNode
    
    Returns:
    the parent node, or null if this node is the root node
  - getValue
```
public java.lang.Object getValue()
```
    Description copied from interface: TreeNode
    
    Get the value associated with this node. This method can be called on destroyed nodes.
    
    Specified by:
    
    getValue in interface TreeNode
    
    Returns:
    the value
  - isChildLeaf
```
public boolean isChildLeaf(int index)
```
    Description copied from interface: TreeNode
    
    Check whether or not a child node is a leaf node.
    
    Specified by:
    
    isChildLeaf in interface TreeNode
    
    Parameters:
    index - the index of the child
    
    Returns:
    true if a leaf node, false if not
  - isChildOpen
```
public boolean isChildOpen(int index)
```
    Description copied from interface: TreeNode
    
    Check whether or not a child node is open.
    
    Specified by:
    
    isChildOpen in interface TreeNode
    
    Parameters:
    index - the index of the child
    
    Returns:
    true if open, false if closed
  - isDestroyed
```
public boolean isDestroyed()
```
    Description copied from interface: TreeNode
    
    Check whether or not the current node is destroyed. The node is destroyed when it is closed, even if it still appears in the tree as an unopened non-leaf node. Once a node is destroyed, calling most methods on the node results in an IllegalStateException.
    
    Specified by:
    
    isDestroyed in interface TreeNode
    
    Returns:
    true if destroyed, false if active
  - setChildOpen

                    boolean open)
```
    Description copied from interface: TreeNode
    
    Open or close a child node and fire an event. If open is true and the TreeNode successfully opens, returns the child TreeNode. Delegates to TreeNode.setChildOpen(int,boolean, boolean).
    
    Specified by:
    
    setChildOpen in interface TreeNode
    
    Parameters:
    index - the index of the child
    open - true to open, false to close
    
    Returns:
    the TreeNode that was opened, or null if the node was closed or could not be opened
  - setChildOpen
```
public TreeNode setChildOpen(int index,
                    boolean open,
                    boolean fireEvents)
```
    Description copied from interface: TreeNode
    
    Open or close the node, optionally firing an event. If open is true and the TreeNode successfully opens, returns the child TreeNode.
    
    Specified by:
    
    setChildOpen in interface TreeNode
    
    Parameters:
    index - the index of the child
    open - true to open, false to flose
    fireEvents - true to fire an event, false not to
    
    Returns:
    the TreeNode that was opened, or null if the node was closed or could not be opened
  - getDisplay
```
CellBrowser.BrowserCellList<C> getDisplay()
```
  - getFocusedKey
```
java.lang.Object getFocusedKey()
```
