javax.swing.filechooser.FileView

FileView defines an abstract class that can be implemented to provide the filechooser with UI information for a File. Each L&F JFileChooserUI object implements this class to pass back the correct icons and type descriptions specific to that L&F. For example, the Microsoft Windows L&F returns the generic Windows icons for directories and generic files. Additionally, you may want to provide your own FileView to JFileChooser to return different icons or additional information using JFileChooser.setFileView(javax.swing.filechooser.FileView).

JFileChooser first looks to see if there is a user defined FileView, if there is, it gets type information from there first. If FileView returns null for any method, JFileChooser then uses the L&F specific view to get the information. So, for example, if you provide a FileView class that returns an Icon for JPG files, and returns null icons for all other files, the UI's FileView will provide default icons for all other files.

For an example implementation of a simple file view, see yourJDK/demo/jfc/FileChooserDemo/ExampleFileView.java. For more information and examples see How to Use File Choosers, a section in The Java Tutorial.

Constructor.
raw docstring

get-descriptionclj

(get-description this f)

A human readable description of the file. For example, a file named jag.jpg might have a description that read: "A JPEG image file of James Gosling's face".

f - java.io.File

returns: java.lang.String

A human readable description of the file. For example,
 a file named jag.jpg might have a description that read:
 "A JPEG image file of James Gosling's face".

f - `java.io.File`

returns: `java.lang.String`
raw docstring

get-iconclj

(get-icon this f)

The icon that represents this file in the JFileChooser.

f - java.io.File

returns: javax.swing.Icon

The icon that represents this file in the JFileChooser.

f - `java.io.File`

returns: `javax.swing.Icon`
raw docstring

get-nameclj

(get-name this f)

The name of the file. Normally this would be simply f.getName().

f - java.io.File

returns: java.lang.String

The name of the file. Normally this would be simply
 f.getName().

f - `java.io.File`

returns: `java.lang.String`
raw docstring

get-type-descriptionclj

(get-type-description this f)

A human readable description of the type of the file. For example, a jpg file might have a type description of: "A JPEG Compressed Image File"

f - java.io.File

returns: java.lang.String

A human readable description of the type of the file. For
 example, a jpg file might have a type description of:
 "A JPEG Compressed Image File"

f - `java.io.File`

returns: `java.lang.String`
raw docstring

traversable?clj

(traversable? this f)

Whether the directory is traversable or not. This might be useful, for example, if you want a directory to represent a compound document and don't want the user to descend into it.

f - java.io.File

returns: java.lang.Boolean

Whether the directory is traversable or not. This might be
 useful, for example, if you want a directory to represent
 a compound document and don't want the user to descend into it.
