java.awt.event.FocusEvent (JDK 1.1)

An event of this type indicates that a Component has gained or lost focus on a temporary or permanent basis.

Use the inherited getComponent() method to determine which component has gained or lost focus. Use getID() to determine the type of focus event; it returns FOCUS_GAINED or FOCUS_LOST.

When focus is lost, you can call isTemporary() to determine whether it is a temporary loss of focus. Temporary focus loss occurs when the window that contains the component loses focus, for example, or when focus is temporarily diverted to a popup menu or a scrollbar. Similarly, you can also use isTemporary() to determine whether focus is being granted to a component on a temporary basis.

public class FocusEvent extends ComponentEvent {
 // Public Constructors public FocusEvent(Component source, int id, boolean temporary);
public FocusEvent(Component source, int id); // Constants public static final int FOCUS_FIRST;
public static final int FOCUS_GAINED;
public static final int FOCUS_LAST;
public static final int FOCUS_LOST; // Public Instance Methods public boolean isTemporary();
public String paramString(); // Overrides ComponentEvent
