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);
    See Also:
    EdalFileChooser.setFileFilter(de.ipk_gatersleben.bit.bi.edal.rmi.client.util.EdalAbstractFileFilter)
