class org.aswing.tree.FHTreeStateNode extends DefaultMutableTreeNode

FHTreeStateNode is used to track what has been expanded. FHTreeStateNode differs from VariableHeightTreeState.TreeStateNode in that it is highly model intensive. That is almost all queries to a FHTreeStateNode result in the TreeModel being queried. And it obviously does not support variable sized row heights. @author paling

function new(layoutCache:FixedHeightLayoutCache, userObject:Dynamic, childIndex:Int, row:Int): Void

function adjustRowBy(amount:Int, ?startIndex:Int = -2): Void

adjustRowBy(amount:int, startIndex:int)
Adjusts this node, its child, and its parent starting at an index of index index is the index of the child to start adjusting from, which is not necessarily the model index.

adjustRowBy(amount:int)
or adjustRowBy(amount:int, -2)
Adjusts the receiver, and all its children rows by amount.

function childInsertedAtModelIndex(index:Int, isExpandedAndVisible:Bool): Void

Messaged when a child has been inserted at index. For all the children that have a childIndex >= index their index is incremented by one.

function collapse(adjustRows:Bool): Void

Collapses the receiver. If adjustRows is true, the rows of nodes after the receiver are adjusted.

function createChildFor(userObject:Dynamic): FHTreeStateNode

Creates a new node to represent userObject. This does NOT check to ensure there isn't already a child node to manage userObject.

function expand(): Void

Expands the receiver.

function getChildAtModelIndex(index:Int): FHTreeStateNode

Returns the child for the passed in model index, this will return null if the child for index * has not yet been created (expanded).

function getChildIndex(): Int

Returns the index of the receiver in the model.

function getPathForRow(row:Int, nextRow:Int, info:SearchInfo): Bool

Returns true if there is a row for row. nextRow gives the bounds of the receiver. Information about the found row is returned in info. This should be invoked on root with nextRow set to getRowCount().

function getRow(): Int

Returns the row of the receiver.

function getRowToModelIndex(index:Int): Int

Returns the row of the child with a model index of index.

function getTotalChildCount(): Int

Returns the number of children in the receiver by descending all expanded nodes and messaging them with getTotalChildCount.

function getTreePath(): TreePath

Returns the TreePath of the receiver.

function getVisibleLevel(): Int

The highest visible nodes have a depth of 0.

function isExpanded(): Bool

Returns true if this node is expanded.

function isLeaf(): Bool

Returns true if the receiver is a leaf.

function isVisible(): Bool

Returns true if this node is visible. This is determined by asking all the parents if they are expanded.

function makeVisible(): Void

Makes the receiver visible, but invoking expandParentAndReceiver on the superclass.

function removeAt(childIndex:Int): Void

Messaged when this node is removed from its parent, this messages removedFromMapping to remove all the children.

function removeChildAtModelIndex(modelIndex:Int, isChildVisible:Bool): Void

Adds newChild to this nodes children at the appropriate location. The location is determined from the childIndex of newChild.

function resetChildrenRowsFrom(newRow:Int, childIndex:Int, modelIndex:Int): Void

Resets the receivers childrens rows. Starting with the child at childIndex (and modelIndex) to newRow. This uses setRowAndChildren to recursively descend children, and uses resetRowSelection to ascend parents.

function setParent(parent:MutableTreeNode): Void

Messaged when this node is added somewhere, resets the path and adds a mapping from path to this node.

function setPath(p:TreePath): Void

function setRow(r:Int): Void

function setUserObject(o:TreeNode): Void

Messaged to set the user object. This resets the path.
