Versione linguaggio: | ActionScript 3.0 |
Versione prodotto: | Flex 3 |
Versioni runtime: | AIR 1.1 |
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in other words, it can display an out-of-date view of the file system.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view to become out-of-date, or when the user deactivates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.
The <mx:FileSystemDataGrid>
tag inherits all of the tag
attributes of its superclass and adds the following tag attributes:
<mx:FileSystemDataGrid Properties dateFormatString="" directory="null" enumerationMode="directoriesFirst" extensions="null" filterFunction="null" nameCompareFunction="null" selectedPath="null" selectedPaths="null" showExtensions="true" showHidden="false" showIcons="true" Styles directoryIcon="TreeNodeIcon" fileIcon="TreeNodeIcon" Events directoryChange="No default" directoryChanging="No default" fileChoose="No default" />

backHistory:Array
[sola lettura] Versione linguaggio: | ActionScript 3.0 |
Versione prodotto: | Flex 3 |
Versioni runtime: | 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);"/>

directory | proprietà |
directory:File
Versione linguaggio: | ActionScript 3.0 |
Versione prodotto: | Flex 3 |
Versioni 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 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.

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

Versioni 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

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
