path. |
Enumeration<TreePath> |
getVisiblePathsFrom(TreePath path) |
Returns an
Enumerator that increments over the visible paths
starting at the passed in location. |
void |
invalidatePathBounds(TreePath path) |
Instructs the
LayoutCache that the bounds for
path are invalid, and need to be updated. |
void |
invalidateSizes() |
Informs the
TreeState that it needs to recalculate
all the sizes it is referencing. |
boolean |
isExpanded(TreePath path) |
Returns true if the value identified by
path is
currently expanded. |
void |
setExpandedState(TreePath path,
boolean isExpanded) |
Marks the path
path expanded state to
isExpanded. |
void |
setModel(TreeModel newModel) |
Sets the
TreeModel that will provide the data. |
void |
setNodeDimensions(AbstractLayoutCache.NodeDimensions nd) |
Sets the renderer that is responsible for drawing nodes in the tree.
|
void |
setRootVisible(boolean rootVisible) |
Determines whether or not the root node from
the
TreeModel is visible. |
void |
setRowHeight(int rowHeight) |
Sets the height of each cell.
|
void |
treeNodesChanged(TreeModelEvent e) |
Invoked after a node (or a set of siblings) has changed in some
way.
|
void |
treeNodesInserted(TreeModelEvent e) |
Invoked after nodes have been inserted into the tree.
|
void |
treeNodesRemoved(TreeModelEvent e) |
Invoked after nodes have been removed from the tree.
|
void |
treeStructureChanged(TreeModelEvent e) |
Invoked after the tree has drastically changed structure from a
given node down.
