public class EdalFileChooser
extends EdalTitleDialog

EDALFileChooser provides a simple mechanism for the user to choose a file from EDAL File System. The following code pops up a file chooser for the user that sees only .jpg and .gif images:

 EDALFileChooser chooser = new EDALFileChooser((Frame) window, rootDirectory);
 EdalFileNameExtensionFilter filter = new EdalFileNameExtensionFilter("JPG & GIF Images", "jpg", "gif");
 chooser.setFileFilter(filter);
 int returnVal = chooser.showOpenDialog();
 if (returnVal == EDALFileChooser.APPROVE_OPTION) {
        System.out.println("You chose to open this file: " + chooser.getSelectedFile().getName());
 }
 

attribute: isContainer false description: A component which allows for the interactive selection of a file.
