Installation

1. Add CN1FileChooser.cn1lib to your project's lib directory and refresh your cn1libs.

Code Sample:

if (FileChooser.isAvailable()) {
    FileChooser.showOpenDialog(".xls, .csv, text/plain", e2-> {
        String file = (String)e2.getSource();
        if (file == null) {
            hi.add("No file was selected");
            hi.revalidate();
        } else {
           String extension = null;
           if (file.lastIndexOf(".") > 0) {
               extension = file.substring(file.lastIndexOf(".")+1);
           }
           if ("txt".equals(extension)) {
               FileSystemStorage fs = FileSystemStorage.getInstance();
               try {
                   InputStream fis = fs.openInputStream(file);
                   hi.addComponent(new SpanLabel(Util.readToString(fis)));
               } catch (Exception ex) {
                   Log.e(ex);
               }
           } else {
               hi.add("Selected file "+file);
           }
        }
        hi.revalidate();
    });
}
