类 ChooseFileView

java.lang.Object

javax.swing.filechooser.FileView

com.fr.design.style.ChooseFileView

public class ChooseFileView
extends javax.swing.filechooser.FileView

A convenience implementation of the FileView interface that manages name, icon, traversable, and file type information.

This this implementation will work well with file systems that use "dot" extensions to indicate file type. For example: "picture.gif" as a gif image.

If the java.io.File ever contains some of this information, such as file type, icon, and hidden file inforation, this implementation may become obsolete. At minimum, it should be rewritten at that time to use any new type information provided by java.io.File

Example: JFileChooser chooser = new JFileChooser(); fileView = new ChooseFileView(); fileView.putIcon("jpg", new ImageIcon("images/jpgIcon.jpg")); fileView.putIcon("gif", new ImageIcon("images/gifIcon.gif")); chooser.setFileView(fileView);

isRootFile

public boolean isRootFile(java.io.File file)

Is root file

getName

public java.lang.String getName(java.io.File f)

The name of the file. Do nothing special here. Let the system file view handle this.

覆盖:

getName 在类中 javax.swing.filechooser.FileView

FileView.getName(java.io.File)

putDescription

public void putDescription(java.io.File f,
                  java.lang.String fileDescription)

Adds a human readable description of the file.

getDescription

public java.lang.String getDescription(java.io.File f)

A human readable description of the file.

覆盖:

getDescription 在类中 javax.swing.filechooser.FileView

另请参阅:

FileView.getDescription(java.io.File)

putTypeDescription

public void putTypeDescription(java.lang.String extension,
                      java.lang.String typeDescription)

Adds a human readable type description for files. Based on "dot" extension strings, e.g: ".gif". Case is ignored.

putTypeDescription

public void putTypeDescription(java.io.File f,
                      java.lang.String typeDescription)

Adds a human readable type description for files of the type of the passed in file. Based on "dot" extension strings, e.g: ".gif". Case is ignored.

getTypeDescription

public java.lang.String getTypeDescription(java.io.File f)

A human readable description of the type of the file.

覆盖:

getTypeDescription 在类中 javax.swing.filechooser.FileView

另请参阅:

FileView.getTypeDescription(java.io.File)

getExtension

public java.lang.String getExtension(java.io.File f)

Conveinience method that returnsa the "dot" extension for the given file.

putIcon

public void putIcon(java.lang.String extension,
           javax.swing.Icon icon)

Adds an icon based on the file type "dot" extension string, e.g: ".gif". Case is ignored.

getIcon

public javax.swing.Icon getIcon(java.io.File f)

Icon that reperesents this file. Default implementation returns null. You might want to override this to return something more interesting.

覆盖:

getIcon 在类中 javax.swing.filechooser.FileView

另请参阅:

FileView.getIcon(java.io.File)

isHidden

public java.lang.Boolean isHidden(java.io.File f)

Whether the file is hidden or not. This implementation returns true if the filename starts with a "."

isTraversable

public java.lang.Boolean isTraversable(java.io.File f)

Whether the directory is traversable or not. Generic implementation returns true for all directories and special folders.

You might want to subtype ChooseFileView to do somethimg more interesting, such as recognize compound documents directories; in such a case you might return a special icon for the diretory that makes it look like a regular document, and return false for isTraversable to not allow users to descend into the directory.

覆盖:

isTraversable 在类中 javax.swing.filechooser.FileView
