public class FixedHeightLayoutCache

NOTE: This will become more open in a future release.
Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running
the same version of Swing. As of 1.4, support for long term storage
of all JavaBeansTM
has been added to the java.beans package.

Rectangle |
getBounds
Returns a rectangle giving the bounds needed to draw path. |
boolean |
getExpandedState
Returns true if the path is expanded, and visible. |
TreePath |
getPathClosestTo
Returns the path to the node that is closest to x,y. |
TreePath |
getPathForRow
Returns the path for passed in row. |
int |
getRowCount
Returns the number of visible rows. |
int |
getRowForPath
Returns the row that the last item identified in path is visible at. |
int |
getVisibleChildCount
Returns the number of visible children for row. |
Enumeration |
getVisiblePathsFrom
Returns an Enumerator that increments over the visible paths starting at the passed in location. |
void |
invalidatePathBounds
Does nothing, FixedHeightLayoutCache doesn't cache width, and that is all that could change. |
void |
invalidateSizes
Informs the TreeState that it needs to recalculate all the sizes it is referencing. |

isExpanded
Returns true if the value identified by row is currently expanded. |
void |
setExpandedState
Marks the path path expanded state to
isExpanded. |
void |
setModel
Sets the TreeModel that will provide the data. |
void |
setRootVisible
Determines whether or not the root node from the TreeModel is visible. |
void |
setRowHeight
Sets the height of each cell. |
void |
treeNodesChanged
Invoked after a node (or a set of siblings) has changed in some way. |
void |

Invoked after nodes have been inserted into the tree. |
void |
treeNodesRemoved
Invoked after nodes have been removed from the tree. |
void |

path - the path being queried

public void treeNodesChanged(TreeModelEvent![]()
![]()
e)
Invoked after a node (or a set of siblings) has changed in some way. The node(s) have not changed locations in the tree or altered their children arrays, but other attributes have changed and may affect presentation. Example: the name of a file has changed, but it is in the same location in the file system.
e.path() returns the path the parent of the changed node(s).
e.childIndices() returns the index(es) of the changed node(s).
