To change the displayed data, rather than using the dataProvider property,
you set the directory property.
The control then automatically populates the dataProvider
property by enumerating the contents of that directory.
You should not set the dataProvider yourself.
You set the directory property to a File instance,
as the following example shows:
<mx:FileSystemList directory="{File.desktopDirectory}"/>
You can set the enumerationMode property to specify
whether to show files, subdirectories, or both.
There are three ways to show both: directories first,
files first, or intermixed.
You can set the extensions property
to filter the displayed items so that only files
with the specified extensions appear.
The showHidden determines whether the control
displays files and subdirectories that the operating system
normally hides.
You can specify an additional filterFunction
to perform custom filtering, and a nameCompareFunction
to perform custom sorting.
Because AIR does not support file system notifications,
this control does not automatically refresh if a file or
subdirectory is created, deleted, moved, or renamed;
in other words, it can display an out-of-date view of the file system.
However, you can call refresh() to re-enumerate
the current directory.
You could, for example, choose to do this when you have
performed a file operation that you know causes the control's
view to become out-of-date, or when the user deactivates
and reactivates your application.
You can use the showIcons property
to show or hide icons, and the showExtensions
property to show or hide file extensions.
The control provides two methods, findItem()
and findIndex(), which you can use to search the
displayed files and subdirectories to find the one
with a specified nativePath.
Two properties, selectedPath
and selectedPaths, work similarly
to selectedItem and selectedItems
or selectedIndex and selectedIndices,
but let you specify the selection via nativePath
strings.
These are very useful if you need to display a directory
with particular items preselected, since in this case
you don't yet have the File items that the control will create
when it enumerates the directory, and you don't know what
their indices will be.
The control allows the user to navigate to other directories
using the mouse or keyboard.
The user can try to change the directory
by double-clicking a subdirectory,
by pressing Enter or Ctrl-Down when a subdirectory is selected,
by pressing Ctrl-Up when the control isn't displaying
the COMPUTER directory, by pressing Ctrl-Left when there is
a "previous" directory to navigate back to, or by pressing Ctrl-Right
when there is a "next" directory to navigate forward to.
If the user attempts to change the directory being displayed,
the control dispatches a cancelable directoryChanging event.
If you don't cancel this event by calling
event.preventDefault(), the control displays the
contents of the new directory and the directory
property changes.
Whenever the directory property changes, for any reason,
the controls dispatches a directoryChange event
to let you know.
In order to support "Up" and "Down" controls, the FileSystemList
has canNavigateUp and canNavigateDown
properties and navigateUp() and navigateDown()
methods. There is also a navigateTo() for navigating
to an arbitrary directory.
The control keeps track of the directories to which the user
has navigated, in order to make it easy for you to support
"Back" and "Forward" controls.
For more information, see the backHistory,
forwardHistory, canNavigateBack,
and canNavigateForward properties, and the
navigateBack() and navigateForward() methods.
Note: The icons displayed for each item are generic file and directory
icons which you can set using the fileIcon
and directoryIcon styles.
Flex's list-based controls currently support displaying
only embedded icons, not icons read at runtime.
Therefore the actual file system icons displayed in the operating system
are not displayed in a FileSystemList, even though they are
accessible in AIR via the icon property of a File.

canNavigateUp | property |
canNavigateUp:Boolean [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | AIR 1.1 |
A flag which is true if the user can navigate up
to a parent directory.
This flag is only false when this control is
displaying the root directories
such as C:\ and D:\ on Microsoft Windows.
(This is the case in which the directory
property is COMPUTER.)
The following example shows how to use this property along with the Button control:
<mx:FileSystemList id="fileSystemViewer" directory="{File.desktopDirectory}"/>
<mx:Button label="Up"
enabled="{fileSystemViewer.canNavigateUp}"

The default value is false.
This property can be used as the source for data binding. When this property is modified, it dispatches the directoryChanged event.
Implementation
public function get canNavigateUp():BooleanRelated API Elements
directory | property |
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 enumerates 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.
Setting this property deselects any previously selected items and causes the control to reset its scroll position to the upper-left corner.
The default value is COMPUTER.
This property can be used as the source for data binding. When this property is modified, it dispatches the directoryChanged event.
Implementation
public function get directory():File public function set directory(value:File):void enumerationMode | property |
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

extensions | property |
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 filterFunction | property |
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):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.
The default value is null.

forwardHistory:Array [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | AIR 1.1 |
An Array of File objects representing directories to which the user can navigate forward.
The first item in this Array is the next directory forward in the history list. The last item is the directory furthest forward in the history list.
This Array may contain the special COMPUTER File object,
which represents the non-existent directory whose contents
are root directories such as C:\ and D:\ on Windows.
The following example shows how to use this property along with the FileSystemHistoryButton control to implement a forward button:
<mx:FileSystemList id="fileSystemViewer" directory="{File.desktopDirectory}"/>
<mx:FileSystemHistoryButton label="Forward"
enabled="{fileSystemViewer.canNavigateForward}"
dataProvider="{fileSystemViewer.forwardHistory}"
click="fileSystemViewer.navigateForward();"

public function get forwardHistory():ArrayRelated API Elements
nameCompareFunction | property |
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.

navigateBack | () | method |
public function navigateBack(index:int = 0):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | AIR 1.1 |
Changes this control to display the contents of a previously-visited
directory in the backHistory array.
If the backHistory array is empty, or if you specify
an index that is not in that array, then this method does nothing.
When this method returns, the directory property
contains the File instance for the new directory.
The dataProvider property is temporarily
null until the new directory has been enumerated.
After the enumeration, the dataProvider property
contains an ArrayCollection of File instances
for the new directory's contents.
The history list is left unchanged. However, the current index
into it changes, which affects the backHistory
and forwardHistory properties.
They have new values as soon as this method returns.
The following example shows how to use this method along with the FileSystemHistoryButton control to create a back button:
<mx:FileSystemList id="fileSystemViewer" directory="{File.desktopDirectory}"/>
<mx:FileSystemHistoryButton label="Back"
enabled="{fileSystemViewer.canNavigateBack}"
dataProvider="{fileSystemViewer.backHistory}"
click="fileSystemViewer.navigateBack();"
itemClick="fileSystemViewer.navigateBack(event.index);"/>
Parameters
index:int (default = 0)backHistory array
to navigate to.
The default is 0, indicating the directory that is "closest back".

refresh | () | method |
public function refresh():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | AIR 1.1 |
Re-enumerates the current directory being displayed by this control.
Because AIR does not support file system notifications,
this control does not automatically refresh if a file or
subdirectory is created, deleted, moved, or renamed;
in other words, it can display an out-of-date view of the file system.
However, you can call refresh() to re-enumerate
the current directory so that it is up-to-date.
You could, for example, choose to do this when you have
performed a file operation that you know causes the control's
view to become stale, or when the user deactivates
and reactivates your application.
This method preserves any selected items (if they still exist) and the scroll position (if the first visible item still exists).
