All Implemented Interfaces:: ImageObserver, MenuContainer, Serializable, Accessible

@JavaBean(defaultProperty="UI", description="A component which allows for the interactive selection of a file.") public class JFileChooserextends 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());
    }

constructor:JFileChooser() [NONE]

JFileChooser

public JFileChooser()

Constructs a JFileChooser pointing to the user's default directory. This default depends on the operating system. It is typically the "Documents" folder on Windows, and the user's home directory on Unix.

constructor:JFileChooser(java.lang.String) [NONE]

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 "Documents" folder on Windows, and the user's home directory on Unix.

Parameters:: currentDirectoryPath - a String giving the path to a file or directory

constructor:JFileChooser(java.io.File) [NONE]

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 "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

constructor:JFileChooser(javax.swing.filechooser.FileSystemView) [NONE]

JFileChooser

public JFileChooser (FileSystemView fsv)

Constructs a JFileChooser using the given FileSystemView.

Parameters:: fsv - a FileSystemView

constructor:JFileChooser(java.io.File,javax.swing.filechooser.FileSystemView) [NONE]

JFileChooser

public JFileChooser (File currentDirectory, FileSystemView fsv)

Constructs a JFileChooser using the given current directory and FileSystemView.

Parameters:: currentDirectory - a File object specifying the path to a file or directory; fsv - a FileSystemView

constructor:JFileChooser(java.lang.String,javax.swing.filechooser.FileSystemView) [NONE]

JFileChooser

public JFileChooser (String currentDirectoryPath, FileSystemView fsv)

Parameters:: view - the FileSystemView used for setup

method:setDragEnabled(boolean) [NONE]

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 the dragEnabled property to

Throws:

HeadlessException - if b is true and GraphicsEnvironment.isHeadless() returns true

Since:

1.4

See Also:

method:getDragEnabled() [NONE]

method:setCurrentDirectory(java.io.File) [NONE]

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 "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

Parameters:: f - a File object

method:showOpenDialog(java.awt.Component) [NONE]

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:

method:showSaveDialog(java.awt.Component) [NONE]

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:

method:showDialog(java.awt.Component,java.lang.String) [NONE]

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.
