Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : AIR 1.1

The FileSystemTree control displays the contents of a file system directory as a tree.

You specify the directory whose content is displayed by setting the directory property to an instance of the flash.filesystem.File class. (File instances can represent directories as well as files.) Whenever this property changes for any reason, the control dispatches a directoryChange event.

You can set the enumerationMode property to specify whether to show this directory's files, its subdirectories, or both. There are three ways to show both files and subdirectories within each tree node: directories first, files first, or intermixed.

You can set the extensions property to filter the list so that only files with the specified extensions are displayed. (Extensions on directories are ignored.) You can also specify an additional filtering function of your own by setting the filterFunction property.

You can use the showExtensions property to show or hide file extensions, and the showIcons property to show or hide icons.

You can do custom-sorting within each tree node by setting the nameCompareFunction property to a function that compares two file or directory names.

If the user double-clicks a closed directory node, or clicks its disclosure icon, this control dispatches a directoryOpening event. If the user double-clicks an open directory node, or clicks its disclosure icon, this control dispatches a directoryClosing event. A handler can cancel either event by calling event.preventDefault() in which case the node doesn't open.

If the user double-clicks a file node, this control dispatches a select event.

Property Detail
AIR-only directoryproperty
directory:File

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : AIR 1.1

The directory whose contents this control displays.

If you set this property to a File object representing an existing directory, the dataProvider immediately becomes null. Later, when this control is revalidated by the LayoutManager, it performs a synchronous enumeration of that directory's contents and populates the dataProvider property with an ArrayCollection of the resulting File objects for the directory's files and subdirectories.

Setting this to a File which does not represent an existing directory is an error. Setting this to COMPUTER synchronously displays the root directories, such as C: and D: on Windows.

The default value is COMPUTER.

This property can be used as the source for data binding.


Implementation
    public function get directory():File
    public function set directory(value:File):void
AIR-only enumerationModeproperty 
enumerationMode:String

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : AIR 1.1

A String specifying whether this control displays only files, only subdirectories, or both. In the case that both are displayed, it also specifies whether the subdirectories are displayed before, after, or mixed in with the files. The possible values are specified by the FileSystemEnumerationMode class.

This property affects which subdirectories and files are displayed in the control, and the order in which they appear. However, it does not affect which File instances are in the dataProvider property; it works by changing the behavior of the filter function that is applied to the dataProvider. Setting it does not cause the current directory to be re-enumerated.

Setting this property deselects any selected items and causes the control to reset its scroll position to the upper-left corner.

The default value is FileSystemEnumerationMode.DIRECTORIES_FIRST.


Implementation
    public function get enumerationMode():String
    public function set enumerationMode(value:String):void

See also

AIR-only extensionsproperty 
extensions:Array

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : AIR 1.1

An Array of extensions specifying which files can be displayed in this control. If this property is set, for example, to [ ".htm", ".html" ], then only files with these extensions can be displayed.

Extensions are considered case-insensitive and the preceding dot is optional. For example, specifying ".HTML" is equivalent to specifying "html".

Directories are not subject to extension filtering, even if they have names containing dots.

The enumerationMode and filterFunction properties are also involved in determining which files appear in the control. For example, if this property is [ ".htm", ".html" ], an .html file is not displayed if the enumerationMode property is FileSystemEnumerationMode.DIRECTORIES_ONLY, or if the filterFunction returns false for the file.

If this property is null, no extension filtering occurs, and all files are displayed. If this property is an empty Array, all extensions are filtered out and no files with extensions are displayed.

This property affects which files are displayed in the control. However, it does not affect which File instances are in the dataProvider property; it works by changing the behavior of the filter function that is applied to the dataProvider. Setting it does not cause the current directory to be re-enumerated.

Setting this property deselects any selected items and causes the control to reset its scroll position to the upper-left corner.

The default value is null.


Implementation
    public function get extensions():Array
    public function set extensions(value:Array):void
AIR-only filterFunctionproperty 
filterFunction:Function

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : AIR 1.1

A callback Function that you can use to perform additional filtering, after the enumerationMode and extensions properties have been applied, to determine which files and subdirectories are displayed and which are hidden.

This function must have the following signature:

function myFilterFunction(file:File):Boolean
This function should return true to show the specified file or subdirectory and false to hide it.

To ensure that every enumerated file and subdirectory is passed to this function, the enumerationMode property must not be FileSystemEnumerationMode.FILES_ONLY or FileSystemEnumerationMode.DIRECTORIES_ONLY, and the extensions property must be null. Otherwise, these properties cause pre-filtering to occur before this filter function is called.

This property affects which subdirectories and files are displayed in the control. However, it does not affect which File instances are in the dataProvider property; it works by changing the behavior of the filter function that is applied to the dataProvider. Setting it does not cause the current directory to be re-enumerated.

Setting this property deselects any selected items and causes the control to reset its scroll position to the upper-left corner.

The default value is null.

AIR-only nameCompareFunctionproperty 
nameCompareFunction:Function

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : AIR 1.1

A callback Function that you can use to change how file and subdirectory names are compared in order to produce the sort order.

This function must have the following signature:

function myNameCompareFunction(name1:String, name2:String):int

It returns -1 if name1 should sort before name2, 1 if name1 should sort after name2, and 0 if the names are the same.

If you do not set this property, the control performs a case-insensitive, locale-dependent comparison of the two names, by first calling the String method toLocaleLowerCase() on each name and then comparing them with the < and > operators.

If you have set enumerationMode to either FileSystemEnumerationMode.FILES_FIRST or FileSystemEnumerationMode.DIRECTORIES_FIRST, then this method is used to compare names only within the separate groups of files and directories.

This property affects the order in which subdirectories and files are displayed in the control. However, it does not affect which File instances are in the dataProvider property; it works by changing the behavior of the sort that is applied to the dataProvider. Setting it does not cause the current directory to be re-enumerated.

Setting this property deselects any selected items and causes the control to reset its scroll position to the upper-left corner.

The default value is null.

AIR-only openPathsproperty 
openPaths:Array

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : AIR 1.1

An Array of nativePath Strings for the File items representing the open subdirectories. This Array is empty if no subdirectories are open.

The default value is [].

AIR-only selectedPathproperty 
selectedPath:String

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : AIR 1.1

The nativePath of the File item representing the selected subdirectory or file, or null if no item is selected.

If multiple items are selected, getting this property gives the first path in the selectedPaths array.

Setting this property affects the selectedPaths, selectedItem, selectedItems, selectedIndex, and selectedIndices properties.

The default value is null.

This property can be used as the source for data binding.

AIR-only showExtensionsproperty 
showExtensions:Boolean

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : AIR 1.1

A flag that specifies whether extensions in file names are shown. Set this property to true to show file extensions and to false to hide them. Extensions in directory names are always shown.

Setting this property does not affect which items are displayed, or the order in which they appear. It also does not affect which items are selected, or the scroll position.

The default value is true.


Implementation
    public function get showExtensions():Boolean
    public function set showExtensions(value:Boolean):void
AIR-only showHiddenproperty 
showHidden:Boolean

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : AIR 1.1

A flag that specifies whether files and directories that the operating system considers hidden are displayed. Set this property to true to show hidden files and directories and to false to hide them.

Setting this property deselects any selected items and causes the control to reset its scroll position to the upper-left corner.

The default value is false.


Implementation
    public function get showHidden():Boolean
    public function set showHidden(value:Boolean):void
AIR-only showIconsproperty 
showIcons:Boolean

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : AIR 1.1

A flag that specifies that icons are displayed before the file name. Set this property to true to show icons and to false to hide them.

You can set the directoryIcon and fileIcon styles to change the default icons. This control cannot display the actual icon that the operating system displays for a file, because AIR does not support that feature.

Setting this property does not affect which items are displayed, or the order in which they appear. It also does not affect which items are selected, or the scroll position.

The default value is true.
