public class JFileChooser

extends JComponent

implements Accessible

JFileChooser provides a simple mechanism for the user to chooser a file. The following pops up a file chooser in the users home directory that only sees .jpg and .gif images: JFileChooser chooser = new JFileChooser(); // Note: source for ExtensionFileFilter can be found in the SwingSet demo ExtensionFileFilter filter = new ExtensionFileFilter(); 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()

Creates a JFileChooser pointing to the user's home directory.

Creates a JFileChooser using the given path. Passing in a null string causes the file chooser to point to the users home directory.

Parameters:

path - a String giving the path to a file or directory

JFileChooser

public JFileChooser(File currentDirectory)

Creates a JFileChooser using the given File as the path. Passing in a null file causes the file chooser to point to the users's home directory.

Parameters:

directory - a File object specifying the path to a file or directory

JFileChooser

public JFileChooser(FileSystemView fsv)

Creates a JFileChooser using the given FileSystemView

JFileChooser

public JFileChooser(File currentDirectory,
                    FileSystemView fsv)

Creates a JFileChooser using the given current directory and FileSystemView

JFileChooser

public JFileChooser(String currentDirectoryPath,
                    FileSystemView fsv)

Creates a JFileChooser using the given current directory path and FileSystemView

Method Detail

setup

protected void setup(FileSystemView view)

Perform common constructor initialization and setup

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 int 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:

selectedFile - the selected file

See Also:

getSelectedFile()

getSelectedFiles

public File[] getSelectedFiles()

Returns a list of selected files if the filechooser is set to allow multi-selection.

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 filechooser to point to the users's home directory. 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 direcotry, or hits the root of the file system.

Parameters:

currentDirectory - 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()

showOpenDialog

public int showOpenDialog(Component parent)

Pops up an "Open File" file chooser dialog. Note that the text that appears in the approve button is determined by the L&F.

Returns:

the return state of the filechooser on popdown: CANCEL_OPTION, APPROVE_OPTION

showSaveDialog

public int showSaveDialog(Component parent)

Pops up a "Save File" file chooser dialog. Note that the text that appears in the approve button is determined by the L&F.

Returns:

the return state of the filechooser on popdown: CANCEL_OPTION, APPROVE_OPTION

showDialog

public int showDialog(Component parent,
                      String approveButtonText)

Pops a custom file chooser dialog with a custom ApproveButton. e.g. filechooser.showDialog(parentWindow, "Run Application"); would pop up a filechooser with a "Run Application" button (instead of the normal "Save" or "Open" button). Alternatively, the following code will do the same thing: JFileChooser chooser = new JFileChooser(null); chooser.setApproveButtonText("Run Application"); chooser.showDialog(this, null); PENDING(jeff) - the following method should be added to the api: showDialog(Component parent);

Parameters:

the return state of the filechooser on popdown: CANCEL_OPTION, APPROVE_OPTION

getDialogType

public int getDialogType()

setDialogType

public void setDialogType(int dialogType)

Sets the type of this dialog. Use OPEN_DIALOG when you want to bring up a filechooser 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 filechooser in a context other than "Open" or "Save". For instance, you might want to bring up a filechooser that allows the user to choose a file to execute. Note that you normally would not need to set the FileChooser to use CUSTOM_DIALOG since a call to setApproveButtonText does this for you.

Parameters:

dialogType - the type of dialog to be displayed: OPEN_DIALOG, SAVE_DIALOG, CUSTOM_DIALOG
