public class FileChooserButton extends HBox implements FileChooser
This Widget implements the FileChooser interface, which has most of the methods necessary to manipulate the selection in the Widget.
Note that FileChooserButton only supports selecting files (mode
OPEN
) or directories (mode
SELECT_FOLDER
). If you need
something more complicated, then you'll need to use wrap a
FileChooserWidget in a custom Widget or launch a FileChooserDialog.
