Class JnaFileChooser

java.lang.Object
anlavn.ui.filechooser.JnaFileChooser
public class JnaFileChooser extends Object
JnaFileChooser is a wrapper around the native Windows file chooser and folder browser that falls back to the Swing JFileChooser on platforms other than Windows or if the user chooses a combination of features that are not supported by the native dialogs (for example multiple selection of directories). Example: JnaFileChooser fc = new JnaFileChooser(); fc.setFilter("All Files", "*"); fc.setFilter("Pictures", "jpg", "jpeg", "gif", "png", "bmp"); fc.setMultiSelectionEnabled(true); fc.setMode(JnaFileChooser.Mode.FilesAndDirectories); if (fc.showOpenDialog(parent)) { Files[] selected = fc.getSelectedFiles(); // do something with selected }
