Constructor Detail

FileChooserFilter

Creates a default FileChooserFilter. Such a FileChooserFilter is useful only if the client overrides the accept and getDescription methods.

FileChooserFilter

public FileChooserFilter(String pattern)

This pattern consists of a wildcard pattern (or a series of wildcard patterns separated by semicolons) similar to those by a Unix shell. For example, to match all files ending with the extensions .html or .htm, you could use the following constructor call:

      new FileChooserPattern("*.html;*.htm")
 

Parameters:

pattern - The filename pattern
