What is New (see all changes)?

Nov 16 '10 It's possible to define whether the quick search is enabled or disabled in TreeView.
Methods setQuickSearchAllowed() and isQuickSearchAllowed() added to TreeView to control quick search enable or disable.
Oct 4 '10 It's possible to define whether the default action is allowed or not in OutlineView.
Methods setDefaultActionAllowed() and isDefaultActionAllowed() added to OutlineView to control invocation of the default action.
Jul 7 '10 OutlineView can provide horizontal scroll bar in the tree column.
In order to be able to provide horizontal scroll bar in the tree column, two methods are added: getTreeHorizontalScrollBarPolicy() and setTreeHorizontalScrollBarPolicy().
Apr 24 '10 ListView can now display ".." item
To simplify navigation "up" in the ListView one can turn on showParentNode property.
Jan 11 '10 OutlineView.setPropertyColumns, OutlineView.addPropertyColumn and OutlineView.removePropertyColumn added.
Added methods to manipulate the displayed columns of an OutlineView without needing to create prototype property objects, both making it simpler to use, and avoiding the common problem of properties not appearing because the prototype property does not use the exact type required.
Deprecated OutlineView.setProperties(), as this was only needed for ease of replacement of TreeTableView.

Specified in What Document?

org.openide.explorer.VisualizerNode.prefetchCount

Exported

Private

Setting this property to integer number controls prefetching of nodes when VisualizerChildren are constructed (prefetchCount = 0 disables prefetching). The prefetching should eliminate "bounce" effect (see #144718) in lazy implementation which is caused by the fact that there exist keys without nodes. In such case "dummy" nodes are created and remove event is fired. This undesirable effect is eliminated by prefetching selected number of nodes so "dummy" nodes are detected and removed in advance before any visualization occurs.

netbeans.dnd.enabled

Exported

Private

Checks by Drag & Drop support for views. True is regard as default (no matter what jdk's version). False value disallows Drag & Drop in all views.

Group of property interfaces

Interface Name	In/Out	Stability	Specified in What Document?
customDelete	Exported	Under Development	Nodes returing Boolean.TRUE from getValue("customDelete") are assumed to provide their own confirmation dialog for delete action and explorer will not show default one when they are deleted.
