By default, a leaf is represented by a text label next to a file icon. A branch is represented by a text label next to a folder icon, with a disclosure triangle that a user can open to expose children.
The Tree class uses an ITreeDataDescriptor or ITreeDataDescriptor2 object to parse and
manipulate the data provider.
The default tree data descriptor, an object of the DefaultDataDescriptor class,
supports XML and Object classes; an Object class data provider must have all children
in children fields.
The Tree control has the following default sizing characteristics:
| Characteristic | Description |
|---|---|
| Default size | Wide enough to accommodate the icon, label, and expansion triangle, if any, of the widest node in the first 7 displayed (uncollapsed) rows, and seven rows high, where each row is 20 pixels in height. If a scroll bar is required, the width of the scroll bar is not included in the width calculations. |
| Minimum size | 0 pixels. |
| Maximum size | 5000 by 5000. |

dataDescriptor:mx.controls.treeClasses:ITreeDataDescriptor| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
Returns the current ITreeDataDescriptor.
De standaardwaarde is DefaultDataDescriptor.
Implementatie

dataProvider:Object[overschrijven] | Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
An object that contains the data to be displayed. When you assign a value to this property, the Tree class handles the source data object as follows:
- A String containing valid XML text is converted to an XMLListCollection.
- An XMLNode is converted to an XMLListCollection.
- An XMLList is converted to an XMLListCollection.
- Any object that implements the ICollectionView interface is cast to an ICollectionView.
- An Array is converted to an ArrayCollection.
- Any other type object is wrapped in an Array with the object as its sole entry.
De standaardwaarde is null.
Deze eigenschap kan als de bron voor gegevensbinding worden gebruikt. Wanneer deze eigenschap wordt gewijzigd, wordt de gebeurtenis collectionChange verzonden.

dragMoveEnabled:Boolean[overschrijven] | Taalversie: | ActionScript 3.0 |

De standaardwaarde is true.

firstVisibleItem:Object| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
The item that is currently displayed in the top row of the tree. Based on how the branches have been opened and closed and scrolled, the top row might hold, for example, the ninth item in the list of currently viewable items which in turn represents some great-grandchild of the root. Setting this property is analogous to setting the verticalScrollPosition of the List control. If the item isn't currently viewable, for example, because it is under a nonexpanded item, setting this property has no effect.
NOTE: In Flex 1.0 this property was typed as XMLNode although it really was either an XMLNode or TreeNode. In 2.0, it is now the generic type Object and will return an object of the same type as the data contained in the dataProvider.
The default value is the first item in the Tree control.
Deze eigenschap kan als de bron voor gegevensbinding worden gebruikt. Wanneer deze eigenschap wordt gewijzigd, wordt de gebeurtenis firstVisibleItemChanged verzonden.

itemIcons | eigenschap |
public var itemIcons:Object| Taalversie: | ActionScript 3.0 |

| Runtimeversies: | Flash Player 9, AIR 1.1 |
An object that specifies the icons for the items. Each entry in the object has a field name that is the item UID and a value that is an an object with the following format:
{iconID: Class, iconID2: Class}
The iconID field value is the class of the icon for
a closed or leaf item and the iconID2 is the class
of the icon for an open item.
This property is intended to allow initialization of item icons.
Changes to this array after initialization are not detected
automatically.
Use the setItemIcon() method to change icons dynamically.
De standaardwaarde is undefined.

maxHorizontalScrollPosition:Number[overschrijven] | Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
The maximum value for the maxHorizontalScrollPosition property for the Tree control.
Unlike the maxHorizontalScrollPosition property
in the List control, this property is modified by the Tree control as
items open and close and as items in the tree otherwise become
visible or are hidden (for example, by scrolling).
If you set this property to the widest known item in the dataProvider,
the Tree control modifies it so that even if that widest item
is four levels down in the tree, the user can scroll to see it.
As a result, although you read back the same value for the
maxHorizontalScrollPosition property that you set,
it isn't necessarily the actual value used by the Tree control.
De standaardwaarde is 0.

showRoot:Boolean| Taalversie: | ActionScript 3.0 |

Sets the visibility of the root item.
If the dataProvider data has a root node, and this is set to
false, the Tree control does not display the root item.
Only the decendants of the root item are displayed.
This flag has no effect on non-rooted dataProviders, such as List and Array.
De standaardwaarde is true.

Methodedetails
dragCompleteHandler | () | methode |
override protected function dragCompleteHandler(event:DragEvent):void| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
Handles DragEvent.DRAG_COMPLETE events. This method
removes the item from the data provider.
Parameters
event:DragEvent — The DragEvent object.
|
dragDropHandler | () | methode |
override protected function dragDropHandler(event:DragEvent):void| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
Handles DragEvent.DRAG_DROP events. This method hides
the drop feedback by calling the hideDropFeedback() method.
If the action is a COPY,
then this method makes a deep copy of the object
by calling the ObjectUtil.copy() method,
and replaces the copy's uid property (if present)
with a new value by calling the UIDUtil.createUID() method.
Parameters
event:DragEvent — The DragEvent object.

expandChildrenOf | () | methode |
public function expandChildrenOf(item:Object, open:Boolean):void| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
Opens or closes all the tree items below the specified item.
If you set dataProvider and then immediately call
expandChildrenOf() you may not see the correct behavior.
You should either wait for the component to validate
or call the validateNow() method.
Parameters
item:Object — The starting item.
| |
open:Boolean — Toggles an open or close operation.
Specify true to open the items, and false to close them.
|
expandItem | () | methode |
public function expandItem(item:Object, open:Boolean, animate:Boolean = false, dispatchEvent:Boolean = false, cause:Event = null):void| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
Opens or closes a branch item.
When a branch item opens, it restores the open and closed states
of its child branches if they were already opened.
If you set dataProvider and then immediately call
expandItem() you may not see the correct behavior.
You should either wait for the component to validate
or call validateNow().
Parameters
item:Object — Item to affect.
| |
open:Boolean — Specify true to open, false to close.
| |
animate:Boolean (default = false)true to animate the transition. (Note:
If a branch has over 20 children, it does not animate the first time it opens,
for performance reasons.)

after the open animation is complete.
| |
cause:Event (default = null) |
getParentItem | () | methode |
public function getParentItem(item:Object):*| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
Returns the known parent of a child item. This method returns a value
only if the item was or is currently visible. Top level items have a
parent with the value null.
Parameters
item:Object — item for which to get the parent.
|
* — The parent of the item.
|

| Runtimeversies: | Flash Player 9, AIR 1.1 |
Sets the associated icon for the item. Calling this method overrides the
iconField and iconFunction properties for
this item if it is a leaf item. Branch items don't use the
iconField and iconFunction properties.
They use the folderOpenIcon and folderClosedIcon properties.
Parameters
item:Object — Item to affect.

iconID:Class — Linkage ID for the closed (or leaf) icon.
| |
iconID2:Class — Linkage ID for the open icon.
