public class JFileChooser
extends JComponent
implements Accessible
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 - a String 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 - a File object specifying the path to a file or directory

JFileChooser

public JFileChooser(FileSystemView fsv)

Constructs a JFileChooser using the given FileSystemView.

JFileChooser

public JFileChooser(File currentDirectory,
                    FileSystemView fsv)

Constructs a JFileChooser using the given current directory and FileSystemView.

JFileChooser

public JFileChooser(String currentDirectoryPath,
                    FileSystemView fsv)

Constructs a JFileChooser using the given current directory path and FileSystemView.

Method Detail

setup

protected void setup(FileSystemView view)

Performs common constructor initialization and setup.

setDragEnabled

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 the dragEnabled property to
Throws:: HeadlessException - if b is true and GraphicsEnvironment.isHeadless() returns true
Since:: 1.4
See Also:: GraphicsEnvironment.isHeadless(), getDragEnabled(), JComponent.setTransferHandler(javax.swing.TransferHandler), TransferHandler

getDragEnabled

public boolean getDragEnabled()

Gets the value of the dragEnabled property.

Returns:: the value of the dragEnabled property
Since:: 1.4
See Also:: setDragEnabled(boolean)

getSelectedFile

public File getSelectedFile()

Returns the selected file. This can be set either by the programmer via setFile 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

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:: getSelectedFile()

getSelectedFiles

public File[] getSelectedFiles()

Returns a list of selected files if the file chooser is set to allow multiple selection.

setSelectedFiles

public void setSelectedFiles(File[] selectedFiles)

Sets the list of selected files if the file chooser is set to allow multiple selection.

getCurrentDirectory

public File getCurrentDirectory()

Returns the current directory.

Returns:: the current directory
See Also:: setCurrentDirectory(java.io.File)

setCurrentDirectory

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:: getCurrentDirectory()

rescanCurrentDirectory

public void rescanCurrentDirectory()

Tells the UI to rescan its files list from the current directory.

ensureFileIsVisible

public void ensureFileIsVisible(File f)

Makes sure that the specified file is viewable, and not hidden.

Parameters:: f - 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 be null; see showDialog 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.

showSaveDialog

public int showSaveDialog(Component parent)
                   throws HeadlessException

Pops up a "Save 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 be null; see showDialog 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.

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 be null

approveButtonText - the text of the ApproveButton

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 in the parent's frame. This method can be overriden to further manipulate the dialog, to disable resizing, set the location, etc. Example:

     class MyFileChooser extends JFileChooser {
         protected JDialog createDialog(Component parent) throws HeadlessException {
             JDialog dialog = super.createDialog(parent);
             dialog.setLocation(300, 200);
             dialog.setResizable(false);
             return dialog;
         }
     }

Parameters:: parent - the parent component of the dialog; can be null
Returns:: a new JDialog containing this instance
Throws:: HeadlessException - if GraphicsEnvironment.isHeadless() returns true.
Since:: 1.4
See Also:: GraphicsEnvironment.isHeadless()

getControlButtonsAreShown

public boolean getControlButtonsAreShown()

Returns the value of the controlButtonsAreShown property.

Returns:: the value of the controlButtonsAreShown property

See Also:: setControlButtonsAreShown(boolean)

setControlButtonsAreShown

public void setControlButtonsAreShown(boolean b)

Sets the property that indicates whether the approve and cancel buttons are shown in the file chooser. This property is true by default. Look and feels that always show these buttons will ignore the value of this property. This method fires a property-changed event, using the string value of CONTROL_BUTTONS_ARE_SHOWN_CHANGED_PROPERTY as the name of the property.

Parameters:: b - false if control buttons should not be shown; otherwise, true
Since:: 1.3
See Also:: getControlButtonsAreShown(), CONTROL_BUTTONS_ARE_SHOWN_CHANGED_PROPERTY

getDialogType

public int getDialogType()

Returns the type of this dialog. The default is JFileChooser.OPEN_DIALOG.

See Also:

setDialogType(int)

setDialogType

public void setDialogType(int dialogType)

Sets the type of this dialog. Use OPEN_DIALOG when you want to bring up a file chooser that the user can use to open a file. Likewise, use SAVE_DIALOG for letting the user choose a file for saving. Use CUSTOM_DIALOG when you want to use the file chooser in a context other than "Open" or "Save". For instance, you might want to bring up a file chooser that allows the user to choose a file to execute. Note that you normally would not need to set the JFileChooser to use CUSTOM_DIALOG since a call to setApproveButtonText does this for you. The default dialog type is JFileChooser.OPEN_DIALOG.
