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();
        // Note: source for ExampleFileFilter can be found in FileChooserDemo,
        // under the demo/jfc directory in the Java 2 SDK, Standard Edition.
        ExampleFileFilter filter = new ExampleFileFilter();
        filter.addExtension("jpg");
        filter.addExtension("gif");
        filter.setDescription("JPG & GIF Images");
        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());
        }

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 a selection 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.
  See Also:
    `GraphicsEnvironment.isHeadless()`, `showDialog(java.awt.Component, java.lang.String)`

### 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.
  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 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.

### 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

    - JFileChooser.CUSTOM_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`.

  Parameters:
    `dialogType` - the type of dialog to be displayed:
    - JFileChooser.OPEN_DIALOG
    - JFileChooser.SAVE_DIALOG
