public class DisableCommand

A command for disabling a component. Disabling a component involves setting its enabled state to false and setting its cursor to a busy cursor. The command may be executed any number of times with different components and supports undo, and thus provides an easy way to temporarily disable a set of components. For example,

 // create the command
 DisableCommand cmd = new DisableCommand ();
 // apply the command to our container and all its children
 com.sas.swing.visuals.util.Util.apply (container, cmd);
 // do some work
 [...]
 // restore the container and its children back to their original cursors
 cmd.undoAll ();
