@JavaBean(defaultProperty="UI", description="A component which allows for the interactive selection of a file.") public class JFileChooser extends JComponent implements Accessible
JFileChooser
provides a simple mechanism for the user to choose a file. For information about using JFileChooser
, see How to Use File Choosers, a section in The Java Tutorial.
The following code pops up a file chooser for the user's home directory that sees only .jpg and .gif images:
JFileChooser chooser = new JFileChooser(); FileNameExtensionFilter filter = new FileNameExtensionFilter( "JPG & GIF Images", "jpg", "gif"); chooser.setFileFilter(filter); int returnVal = chooser.showOpenDialog(parent); if(returnVal == JFileChooser.APPROVE_OPTION) { System.out.println("You chose to open this file: " + chooser.getSelectedFile().getName()); }
Warning: Swing is not thread safe. For more information see Swing's Threading Policy.

Constructor Detail
JFileChooser
public JFileChooser()
Constructs a JFileChooser
pointing to the user's default directory. This default depends on the operating system. It is typically the "My Documents" folder on Windows, and the user's home directory on Unix.
JFileChooser
public JFileChooser(String currentDirectoryPath)
Constructs a JFileChooser
using the given path. Passing in a null
string causes the file chooser to point to the user's default directory. This default depends on the operating system. It is typically the "My Documents" folder on Windows, and the user's home directory on Unix.
- Parameters:
-
currentDirectoryPath
- aString
giving the path to a file or directory
JFileChooser
public JFileChooser(File currentDirectory)
Constructs a JFileChooser
using the given File
as the path. Passing in a null
file causes the file chooser to point to the user's default directory. This default depends on the operating system. It is typically the "My Documents" folder on Windows, and the user's home directory on Unix.
- Parameters:
-
currentDirectory
- aFile
object specifying the path to a file or directory
JFileChooser
public JFileChooser(FileSystemView fsv)
Constructs a JFileChooser
using the given FileSystemView
.
- Parameters:
-
fsv
- aFileSystemView
JFileChooser
public JFileChooser(File currentDirectory, FileSystemView fsv)
Constructs a JFileChooser
using the given current directory and FileSystemView
.
- Parameters:
-
currentDirectory
- aFile
object specifying the path to a file or directory -
fsv
- aFileSystemView
JFileChooser
public JFileChooser(String currentDirectoryPath, FileSystemView fsv)
Constructs a JFileChooser
using the given current directory path and FileSystemView
.
- Parameters:
-
currentDirectoryPath
- aString
specifying the path to a file or directory -
fsv
- aFileSystemView
Method Detail
setup
protected void setup(FileSystemView view)
Performs common constructor initialization and setup.
- Parameters:
-
view
- theFileSystemView
used for setup
setDragEnabled
@BeanProperty(bound=false, description="determines whether automatic drag handling is enabled") public void setDragEnabled(boolean b)
Sets the dragEnabled
property, which must be true
to enable automatic drag handling (the first part of drag and drop) on this component. The transferHandler
property needs to be set to a non-null
value for the drag to do anything. The default value of the dragEnabled
property is false
.
When automatic drag handling is enabled, most look and feels begin a drag-and-drop operation whenever the user presses the mouse button over an item and then moves the mouse a few pixels. Setting this property to true
can therefore have a subtle effect on how selections behave.
Some look and feels might not support automatic drag and drop; they will ignore this property. You can work around such look and feels by modifying the component to directly call the exportAsDrag
method of a TransferHandler
.
- Parameters:
-
b
- the value to set thedragEnabled
property to - Throws:
-
HeadlessException

public File getSelectedFile()
Returns the selected file. This can be set either by the programmer via setSelectedFile
or by a user action, such as either typing the filename into the UI or selecting the file from a list in the UI.
- Returns:
- the selected file
- See Also:
setSelectedFile(java.io.File)
setSelectedFile
@BeanProperty(preferred=true) public void setSelectedFile(File file)
Sets the selected file. If the file's parent directory is not the current directory, changes the current directory to be the file's parent directory.
- Parameters:
-
file
- the selected file - See Also:

- Returns:
- the current directory
- See Also:
setCurrentDirectory(java.io.File)
setCurrentDirectory
@BeanProperty(preferred=true, description="The directory that the JFileChooser is showing files of.") public void setCurrentDirectory(File dir)
Sets the current directory. Passing in null
sets the file chooser to point to the user's default directory. This default depends on the operating system. It is typically the "My Documents" folder on Windows, and the user's home directory on Unix. If the file passed in as currentDirectory
is not a directory, the parent of the file will be used as the currentDirectory. If the parent is not traversable, then it will walk up the parent tree until it finds a traversable directory, or hits the root of the file system.
- Parameters:
-
dir
- the current directory to point to - See Also:
getCurrentDirectory()
changeToParentDirectory
public void changeToParentDirectory()
Changes the directory to be set to the parent of the current directory.
- See Also:

- a File object
showOpenDialog
public int showOpenDialog(Component parent) throws HeadlessException
Pops up an "Open File" file chooser dialog. Note that the text that appears in the approve button is determined by the L&F.
- Parameters:
-
parent
- the parent component of the dialog, can benull
; seeshowDialog
for details - Returns:
- the return state of the file chooser on popdown:
- JFileChooser.CANCEL_OPTION
- JFileChooser.APPROVE_OPTION
- JFileChooser.ERROR_OPTION if an error occurs or the dialog is dismissed
- Throws:
-
HeadlessException

- Parameters:
-
parent
- the parent component of the dialog, can benull
; seeshowDialog
for details - Returns:
- the return state of the file chooser on popdown:
- JFileChooser.CANCEL_OPTION
- JFileChooser.APPROVE_OPTION
- JFileChooser.ERROR_OPTION if an error occurs or the dialog is dismissed
- Throws:
-
HeadlessException
- if GraphicsEnvironment.isHeadless() returns true. - See Also:
-
GraphicsEnvironment.isHeadless()
,showDialog(java.awt.Component, java.lang.String)
showDialog
public int showDialog(Component parent, String approveButtonText) throws HeadlessException
Pops a custom file chooser dialog with a custom approve button. For example, the following code pops up a file chooser with a "Run Application" button (instead of the normal "Save" or "Open" button):
filechooser.showDialog(parentFrame, "Run Application");Alternatively, the following code does the same thing:
JFileChooser chooser = new JFileChooser(null); chooser.setApproveButtonText("Run Application"); chooser.showDialog(parentFrame, null);
The parent
argument determines two things: the frame on which the open dialog depends and the component whose position the look and feel should consider when placing the dialog. If the parent is a Frame
object (such as a JFrame
) then the dialog depends on the frame and the look and feel positions the dialog relative to the frame (for example, centered over the frame). If the parent is a component, then the dialog depends on the frame containing the component, and is positioned relative to the component (for example, centered over the component). If the parent is null
, then the dialog depends on no visible window, and it's placed in a look-and-feel-dependent position such as the center of the screen.
- Parameters:
-
parent
- the parent component of the dialog; can benull
-
approveButtonText
- the text of theApproveButton
- Returns:
- the return state of the file chooser on popdown:
- JFileChooser.CANCEL_OPTION
- JFileChooser.APPROVE_OPTION
- JFileChooser.ERROR_OPTION if an error occurs or the dialog is dismissed
- Throws:
-
HeadlessException
- if GraphicsEnvironment.isHeadless() returns true. - See Also:
GraphicsEnvironment.isHeadless()
createDialog
protected JDialog createDialog(Component parent) throws HeadlessException
Creates and returns a new JDialog
wrapping this
centered on the parent
