All known Subclasses: components.TaxonomyTreeView, components.SchemaTreeView,
| TreeView | | public class TreeView extends View implements Target,TextFieldOwner(Code) | | TreeView.
Using the BinaryTree enumeration as it's spine,
this widget displays information in a file mangerish fashion.
It is important to note that a selected item in
the TreeView does not correspond directly to the
current position in the BinaryTree.
The reason for this is to allow multiple TreeViews
to view the same BinaryTree.
The "look" is configurable by passing appropriate images
to the constructors.
Open Issues
- Null trees not handled. Some code stubbed in, but
basically on the floor.

|
| getChanged | | public boolean getChanged()(Code) | | |

the currently selected ListItem because some actions need
to occur during transitions from the previously selected
ListItem and the currently selected ListItem.
|
| hideEditButtons | | public void hideEditButtons()(Code) | | Hides the default edit buttons.
Typically used by windows supplying their own menus and
calling the button action methods directly.
Expected to be done as part of construction rather than
during display, so no setDirty() and no showEditButtons().

| newWindow | | public void newWindow()(Code) | | |
