public class TreeViewer
extends AbstractTreeViewer

A concrete viewer based on an SWT Tree control.

This class is not intended to be subclassed outside the viewer framework. It is designed to be instantiated with a pre-existing SWT tree control and configured with a domain-specific content provider, label provider, element filter (optional), and element sorter (optional).

As of 3.2, TreeViewer supports multiple equal elements (each with a different parent chain) in the tree. This support requires that clients enable the element map by calling setUseHashLookup(true).

Content providers for tree viewers must implement either the ITreeContentProvider interface, (as of 3.2) the ILazyTreeContentProvider interface, or (as of 3.3) the ILazyTreePathContentProvider. If the content provider is an ILazyTreeContentProvider or an ILazyTreePathContentProvider, the underlying Tree must be created using the SWT.VIRTUAL style bit, the tree viewer will not support sorting or filtering, and hash lookup must be enabled by calling StructuredViewer.setUseHashlookup(boolean).

Users setting up an editable tree with more than 1 column have to pass the SWT.FULL_SELECTION style bit

Restriction:
This class is not intended to be subclassed by clients.

setChildCount

public void setChildCount(
Object elementOrTreePath,
                          int count)
For a TreeViewer with a tree with the VIRTUAL style bit set, set the number of children of the given element or tree path. To set the number of children of the invisible root of the tree, you can pass the input object or an empty tree path.

Parameters:

                    int index,
                    
Object element)
For a TreeViewer with a tree with the VIRTUAL style bit set, replace the given parent's child at index with the given element. If the given parent is this viewer's input or an empty tree path, this will replace the root element at the given index.

This method should be called by implementers of ILazyTreeContentProvider to populate this viewer.

The default implementation of this framework method calls hasChildren on this viewer's content provider. It may be overridden if necessary.

Overrides:
isExpandable in class AbstractTreeViewer
Parameters:
element - the element or path
Returns:
true if the tree node representing the given element can be expanded, or false if not

getParentElement

protected 
Object getParentElement(
Object element)
Description copied from class: AbstractTreeViewer

Overrides:
getParentElement in class AbstractTreeViewer
Returns:
the parent element, or parent path, or null

createChildren

protected void createChildren(
Widget widget)
Description copied from class: AbstractTreeViewer
Creates all children for the given widget.

The default implementation of this framework method assumes that widget.getData() returns the element corresponding to the node. Note: the node is not visually expanded! You may have to call parent.setExpanded(true).

Overrides:
createChildren in class AbstractTreeViewer
Parameters:
widget - the widget

internalAdd

protected void internalAdd(
Widget widget,
                           
Object parentElement,
                           
Object[] childElements)
Description copied from class: AbstractTreeViewer
Adds the given child elements to this viewer as children of the given parent element.

EXPERIMENTAL. Not to be used except by JDT. This method was added to support JDT's explorations into grouping by working sets, which requires viewers to support multiple equal elements. See bug 76482 for more details. This support will likely be removed in Eclipse 3.2 in favor of proper support for multiple equal elements.

Overrides:
internalAdd in class AbstractTreeViewer
Parameters:
widget - the widget for the parent element
parentElement - the parent element
childElements - the child elements to add

internalRefreshStruct

protected 
ViewerRow getViewerRowFromItem(
