public class MultiTreeUI

extends TreeUI

implements Serializable

uis

The Vector containing the real UI's.

MultiTreeUI()

collapsePath(TreePath)

Insures that the last item identified in path is collapsed and visible.

collapseRow(int)

Insures that the item identified by row is collapsed.

contains(JComponent, int, int)

createUI(JComponent)

expandPath(TreePath)

Insures that the last item identified in path is expanded and visible.

expandRow(int)

Insures that the item identified by row is expanded.

getClosestPathForLocation(int, int)

Returns the path to the node that is closest to x,y.

getClosestRowForLocation(int, int)

Returns the row to the node that is closest to x,y.

getEditingPath()

Returns the path to the element that is being edited.

getMaximumSize(JComponent)

getMinimumSize(JComponent)

getPathBounds(TreePath)

Returns the Rectangle enclosing the label portion that the last item in path will be drawn into.

getPathForRow(int)

Returns the path for passed in row.

getPreferredSize(JComponent)

getRowBounds(int)

Returns the Rectangle enclosing the label portion that the item identified by row will be drawn into.

getRowCount()

Returns the number of rows that are being displayed.

getRowForPath(TreePath)

Returns the row that the last item identified in path is visible at.

getUIs()

Return the list of UI's associated with this multiplexing UI.

installUI(JComponent)

isCollapsed(int)

Returns true if the value identified by row is currently collapsed.

isCollapsed(TreePath)

Returns true if the value identified by path is currently collapsed, this will return false if any of the values in path are currently not being displayed.

isEditing()

Returns true if the tree is being edited.

isExpanded(int)

Returns true if the value identified by row is currently expanded.

isExpanded(TreePath)

Returns true if the value identified by path is currently expanded, this will return false if any of the values in path are currently not being displayed.

isVisible(TreePath)

Returns true if all the parents of path are currently expanded.

makeVisible(TreePath)

Ensures that all of the parents of path are currently expanded.

paint(Graphics, JComponent)

scrollPathToVisible(TreePath)

Makes sure all the path components in path are expanded (accept for the last path component) and tries to scroll the resulting path to be visible (the scrolling will only work if the JTree is contained in a JScrollPane).

scrollRowToVisible(int)

Scrolls the item identified by row to be visible.

startEditingAtPath(TreePath)

Selects the last item in path and tries to edit it.

stopEditing()

Stops the current editing session.

uninstallUI(JComponent)

protected Vector uis

The Vector containing the real UI's. This is populated in the call to createUI, and can be obtained by calling getUIs. The first element is guaranteed to the real UI obtained from the default look and feel.
