public class EdalFileNameExtensionFilter extends EdalAbstractFileFilter
An implementation ofEDALFileFilter
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 aEDALFileNameExtensionFilter
that will showjpg
files:EDALFileFilter filter = new EDALFileNameExtensionFilter("JPEG file", "jpg", "jpeg"); EDALFileChooser fileChooser = ...; fileChooser.setFileFilter(filter);
