java.lang.Objectcom.vlsolutions.swing.toolbars.ToolBarPersistence
public class ToolBarPersistence
This class contains methods to keep a set of toolbars persistent.
The class uses the preferences framework of the java runtime, and installs a shutdown hook to save the toolbars state on application exit.
Warning : this class cannot be run from a sandboxed (untrusted) environment (unsigned applet/ java web start) as it uses classes requiring a SecurityManager (Preferences API and Runtime shutdown hook).
Call loadToolBarLayout() upon application startup, after registering all ToolBars.
