public class JFileChooser
extends javax.swing.JComponent
implements javax.accessibility.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(); 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()); }

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(java.io.File selectedFile)
Sets the selected file. If the file's parent directory is not the current directory, it changed the current directory to be the files parent directory.
Parameters:
selectedFile - the selected file
See Also:
getSelectedFile()

getSelectedFiles

See Also:
setCurrentDirectory(java.io.File)

setCurrentDirectory

public void setCurrentDirectory(java.io.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.

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

showDialog

public int showDialog(java.awt.Component parent,
                      java.lang.String approveButtonText)

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:
approveButtonText - the text of the ApproveButton

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
