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.

A constant that can be used as a value for the directory property,

Detalhes da propriedade
directory | propriedade |
directory:File| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | 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.
O valor padrão é COMPUTER.
Essa propriedade pode ser usada como a origem para o vínculo de dados. Quando essa propriedade é modificada, ela despacha o evento directoryChanged .

enumerationMode:String| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | 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.
O valor padrão é FileSystemEnumerationMode.DIRECTORIES_FIRST.

extensions | propriedade |
extensions:Array| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | 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.
O valor padrão é null.

public function get extensions():Array public function set extensions(value:Array):void filterFunction | propriedade |
filterFunction:Function| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | 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):BooleanThis 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.
O valor padrão é null.

nameCompareFunction:Function| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | 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 nativePath of the File item

gives the first path in the selectedPaths array.

properties.

Set this property to true to show icons

You can set the directoryIcon
and fileIcon styles to change the default icons.
This control cannot display the actual icon that the operating system
