Constructor

	Tree(Composite parent, int style) Constructs a new instance of this class given its parent and a style value describing its behavior and appearance.

Method

void	addKeyListener(KeyListener listener) Adds the listener to the collection of listeners who will be notified when keys are pressed and released on the system keyboard, by sending it one of the messages defined in the `KeyListener` interface.
void	addListener(int eventType, Listener listener) Adds the listener to the collection of listeners who will be notified when an event of the given type occurs.
void	addMouseListener(MouseListener listener) Adds the listener to the collection of listeners who will be notified when mouse buttons are pressed and released, by sending it one of the messages defined in the `MouseListener` interface.
void	addSelectionListener(SelectionListener listener) Adds the listener to the collection of listeners who will be notified when the receiver's selection changes, by sending it one of the messages defined in the `SelectionListener` interface.
void	addTreeListener(TreeListener listener) Adds the listener to the collection of listeners who will be notified when an item in the receiver is expanded or collapsed by sending it one of the messages defined in the `TreeListener` interface.
Point	computeSize(int wHint, int hHint) Returns the preferred size of the receiver.
Rectangle	computeTrim(int x, int y, int width, int height) Given a desired client area for the receiver (as described by the arguments), returns the bounding rectangle which would be required to produce that client area.
Accessible	getAccessible() Returns the accessible object for the receiver.
Rectangle	getClientArea() Returns a rectangle which describes the area of the receiver which is capable of displaying data (that is, not covered by the "trimmings").
TreeColumn	getColumn(int index) Returns the column at the given, zero-relative index in the receiver.
int	getColumnCount() Returns the number of columns contained in the receiver.
int[]	getColumnOrder() Returns an array of zero-relative integers that map the creation order of the receiver's items to the order in which they are currently being displayed.
TreeColumn[]	getColumns() Returns an array of `TreeColumn`s which are the columns in the receiver.
int	getHeaderHeight() Returns the height of the receiver's header
TreeItem	getItem(int index) Returns the item at the given, zero-relative index in the receiver.
TreeItem	getItem(Point point) Returns the item at the given point in the receiver or null if no such item exists.
int	getItemCount() Returns the number of items contained in the receiver that are direct item children of the receiver.
int	getItemHeight() Returns the height of the area which would be used to display one of the items in the tree.
TreeItem[]	getItems() Returns a (possibly empty) array of items contained in the receiver that are direct item children of the receiver.
Object	getLayoutData() Returns layout data which is associated with the receiver.
TreeItem[]	getSelection() Returns an array of `TreeItem`s that are currently selected in the receiver.
int	getSelectionCount() Returns the number of selected items contained in the receiver.
Point	getSize() Returns a point describing the receiver's size.
TreeColumn	getSortColumn() Returns the column which shows the sort indicator for the receiver.
int	getSortDirection() Returns the direction of the sort indicator for the receiver.
TreeItem	getTopItem() Returns the item which is currently at the top of the receiver.
int	indexOf(TreeItem item) Searches the receiver's list starting at the first item (index 0) until an item is found that is equal to the argument, and returns the index of that item.
int	indexOf(TreeColumn column) Searches the receiver's list starting at the first column (index 0) until a column is found that is equal to the argument, and returns the index of that column.
boolean	isDisposed() Returns `true` if the widget has been disposed, and `false` otherwise.
void	select(TreeItem item) Selects an item in the receiver.
void	setBounds(int x, int y, int width, int height) Sets the receiver's size and location to the rectangular area specified by the arguments.
void	setColumnOrder(int[] order) Sets the order that the items in the receiver should be displayed in to the given argument which is described in terms of the zero-relative ordering of when the items were added.
void	setEnabled(boolean enabled) Enables the receiver if the argument is `true`, and disables it otherwise.
void	setHeaderVisible(boolean value) Marks the receiver's header as visible if the argument is `true` , and marks it invisible otherwise.
void	setItemCount(int count) Sets the number of root-level items contained in the receiver.
void	setLayoutData(Object layoutData) Sets the layout data associated with the receiver to the argument.
void	setLinesVisible(boolean value) Marks the receiver's lines as visible if the argument is `true`, and marks it invisible otherwise.
void	setMenu(Menu menu) Sets the receiver's pop up menu to the argument.
void	setRedraw(boolean redraw) If the argument is `false`, causes subsequent drawing operations in the receiver to be ignored.
void	setSelection(TreeItem selection) Sets the receiver's selection to the given item.
void	setSelection(TreeItem[] selection) Sets the receiver's selection to be the given array of items.
void	setSize(int width, int height) Sets the receiver's size to the point specified by the arguments.
void	setSortColumn(TreeColumn column) Sets the column used by the sort indicator for the receiver.
void	setSortDirection(int direction) Sets the direction of the sort indicator for the receiver.
void	showItem(TreeItem item) Shows the item.
Point	toControl(Point point) Returns a point which is the result of converting the argument, which is specified in display relative coordinates, to coordinates relative to the receiver.
