public class JFileChooserApplet

extends Applet

Applet used to select files (actually, filepath strings), requires Java plugin. This applet is used in HTML pages to launch a Java file dialog and return the the selected filepath(s) to the HTML page. Visible portion of applet is a button that typically says "Browse..." When the applet button is clicked, a file chooser dialog is launched. The user uses the file dialog to selects file(s) and clicks "Save" (or custom label) button. The filepath (or multiple concatenated filepaths) string is provided to the page by the applet calling the JavaScript method setPath() (or jsSetMethod-specified custom method). Used in single-select mode for selecting primary content files for FormatContentHolder objects (such as WTDocuments), typically in conjunction with an HTML text field to emulate an HTML file input (looks the same, but has much more intelligence). Used in multi-select mode for selecting secondary content of FormatContentHolder objects, and attachments for ContentHolder objects (such as change objects).
