Class EdalFileNameExtensionFilter


  • public class EdalFileNameExtensionFilter
    extends EdalAbstractFileFilter
    An implementation of EDALFileFilter that filters using a specified set of extensions. The extension for a file is the portion of the file name after the last ".". Files whose name does not contain a "." have no file name extension. File name extension comparisons are case insensitive. The following example creates a EDALFileNameExtensionFilter that will show jpg files:
     EDALFileFilter filter = new EDALFileNameExtensionFilter("JPEG file", "jpg", "jpeg");
     EDALFileChooser fileChooser = ...;
     fileChooser.setFileFilter(filter);
