Class WindowHelper

java.lang.Object

slash.navigation.gui.helpers.WindowHelper

public class WindowHelper
extends Object

A helper for JFrame and JDialog operations, and the single choke point for JOptionPane message/confirm/input dialogs. Every wrapper defaults the parent to the main frame and the title to the owner window's title, and bounds long plain-text messages (e.g. stacktraces) in a scroll pane so a dialog can never grow past the screen.
