Language Version: ActionScript 3.0

Runtime Versions: AIR 1.1

The FileSystemDataGrid control lets you display the contents of a single file system directory in a data grid format.

The information displayed for each item consists of its name (with optional generic icon), type, size, creation date, and modification date. To do this, FileSystemDataGrid automatically creates five columns (DataGridColumn instances) -- nameColumn, typeColumn, sizeColumn, creationDateColumn, and modificationDateColumn -- and sets the columns property to an array of these five instances. Each column instance is automatically configured to have an appropriate labelFunction, sortCompareFunction, etc. If you don't want all five columns, or if you want to change the order, reset the columns property. If you want to customize a column, such as by changing its labelFunction, simply reassign that property on the appropriate column object.

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:FileSystemDataGrid 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 property 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refresh if a file or subdirectory is created, deleted, moved, or renamed; in other words, it can display an out-of-date view of the file system.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example, choose to do this when you have performed a file operation that you know causes the control's view to become out-of-date, or when the user deactivates and reactivates your application.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 FileSystemDataGrid, even though they are accessible in AIR via the icon property of a File.

backHistory

property
backHistory: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 backward.

The first item in this Array is the next directory backward in the history list. The last item is the directory furthest backward in the history list.

This Array may contain a null item, which represents the non-existent directory whose contents are root directories such as C:\ and D:\ on Microsoft Windows.

The following example shows how to use this property along with the FileSystemHistoryButton control to implement a back button:

      <mx:FileSystemDataGrid id="fileSystemViewer" directory="{File.desktopDirectory}"/>
      <mx:FileSystemHistoryButton label="Back"
         enabled="{fileSystemViewer.canNavigateBack}"
         dataProvider="{fileSystemViewer.backHistory}"
         click="fileSystemViewer.navigateBack();"
         itemClick="fileSystemViewer.navigateBack(event.index);"/>

The default value is [].

This property can be used as the source for data binding. When this property is modified, it dispatches the historyChanged event.

creationDateColumn

property 
public var creationDateColumn:DataGridColumn

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

The DataGridColumn representing the Created column. The FileSystemDataGrid control automatically creates this column.

You can set properties such as creationDateColumn.width to customize this column. To remove this column entirely, or to change the column order, set the columns property to an array such as [ nameColumn, modificationDateColumn, sizeColumn ].

AIR-only 

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.

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
AIR-only 

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

AIR-only 

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
AIR-only 

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):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 

forwardHistory

property 
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 a null item, 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:FileSystemDataGrid id="fileSystemViewer" directory="{File.desktopDirectory}"/>
      <mx:FileSystemHistoryButton label="Forward"
          enabled="{fileSystemViewer.canNavigateForward}"
          dataProvider="{fileSystemViewer.forwardHistory}"
          click="fileSystemViewer.navigateForward();"
          itemClick="fileSystemViewer.navigateForward(event.index);"/>

The default value is [].

This property can be used as the source for data binding. When this property is modified, it dispatches the historyChanged event.

modificationDateColumn

property 
public var modificationDateColumn:DataGridColumn

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

The DataGridColumn representing the Modified column. The FileSystemDataGrid control automatically creates this column.

You can set properties such as modificationDateColumn.width to customize this column. To remove this column entirely, or to change the column order, set the columns property to an array such as [ nameColumn, modificationDateColumn, sizeColumn ].

AIR-only 

nameColumn

property 
public var nameColumn:DataGridColumn

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

The DataGridColumn representing the Name column. The FileSystemDataGrid control automatically creates this column.

You can set properties such as nameColumn.width to customize this column. To remove this column entirely, or to change the column order, set the columns property to an array such as [ nameColumn, modificationDateColumn, sizeColumn ].

AIR-only 

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.

Product Version: Flex 3
Runtime Versions: AIR 1.1

Searches the File instances currently displayed in this control and returns the one with the specified nativePathproperty.

File instances which are present in the control's collection but not displayed because of filtering are not searched.

Parameters

nativePath:String — A String specifying the nativePath of a File item.

Returns
File — A File instance if one was found with the specified nativePath, or null if none was found.

AIR-only 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:FileSystemDataGrid 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) — The index in the backHistory array to navigate to. The default is 0, indicating the directory that is "closest back".

AIR-only navigateDown

()method 
public function navigateDown():void

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

Changes this control to display the contents of the selected subdirectory.

If a subdirectory is not selected, 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 following example shows how to use this method along with the Button control to create an open button:

      <mx:FileSystemDataGrid id="fileSystemViewer" directory="{File.desktopDirectory}"/>
      <mx:Button label="Open"
          enabled="{fileSystemViewer.canNavigateDown}"
          click="fileSystemViewer.navigateDown();"/>

AIR-only navigateForward

()method 
public function navigateForward(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 forwardHistory array.

If the forwardHistory 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 forward button:

      <mx:FileSystemDataGrid id="fileSystemViewer" directory="{File.desktopDirectory}"/>
      <mx:FileSystemHistoryButton label="Forward"
          enabled="{fileSystemViewer.canNavigateForward}"
          dataProvider="{fileSystemViewer.forwardHistory}"
          click="fileSystemViewer.navigateForward();"
          itemClick="fileSystemViewer.navigateForward(event.index);"/>

Parameters

index:int (default = 0) — The index in the forwardHistory array to navigate to. The default is 0, indicating the directory that is "closest forward".

AIR-only navigateTo

()method 
public function navigateTo(directory:File):void

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

Changes this control to display the contents of the specified directory.

AIR-only navigateUp

()method 
public function navigateUp():void

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

Changes this control to display the contents of the next directory up in the hierarchy.

If this control is currently displaying root directories (such as C: and D: on Microsoft Windows), 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 following example shows how to use this property along with the Button control to create an up button:

      <mx:FileSystemDataGrid id="fileSystemViewer" directory="{File.desktopDirectory}"/>
      <mx:Button label="Up"
          enabled="{fileSystemViewer.canNavigateUp}"
          click="fileSystemViewer.navigateUp();"/>

AIR-only 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).
