WindowListenerpublic interface WindowListener implements EventListenerThe listener interface for receiving window events.
The class that is interested in processing a window event
either implements this interface (and all the methods it
contains) or extends the abstract WindowAdapter class
(overriding only the methods of interest).
The listener object created from that class is then registered with a
Window using the window's addWindowListener
method. When the window's status changes by virtue of being opened,
closed, activated or deactivated, iconified or deiconified,
the relevant method in the listener object is invoked, and the
WindowEvent is passed to it. |
| Methods Summary |
|---|
| public void | windowActivated(java.awt.event.WindowEvent e)Invoked when the Window is set to be the active Window. Only a Frame or
a Dialog can be the active Window. The native windowing system may
denote the active Window or its children with special decorations, such
as a highlighted title bar. The active Window is always either the
focused Window, or the first Frame or Dialog that is an owner of the
focused Window.
| | public void | windowClosed(java.awt.event.WindowEvent e)Invoked when a window has been closed as the result
of calling dispose on the window.
| | public void | windowClosing(java.awt.event.WindowEvent e)Invoked when the user attempts to close the window
from the window's system menu.
| | public void | windowDeactivated(java.awt.event.WindowEvent e)Invoked when a Window is no longer the active Window. Only a Frame or a
Dialog can be the active Window. The native windowing system may denote
the active Window or its children with special decorations, such as a
highlighted title bar. The active Window is always either the focused
Window, or the first Frame or Dialog that is an owner of the focused
Window.
| | public void | windowDeiconified(java.awt.event.WindowEvent e)Invoked when a window is changed from a minimized
to a normal state.
| | public void | windowIconified(java.awt.event.WindowEvent e)Invoked when a window is changed from a normal to a
minimized state. For many platforms, a minimized window
is displayed as the icon specified in the window's
iconImage property.
| | public void | windowOpened(java.awt.event.WindowEvent e)Invoked the first time a window is made visible.
