WindowConstants (Java SE 11 & JDK 11 )

All Known Implementing Classes:

JDialog, JFrame, JInternalFrame

Constants used to control the window-closing operation. The setDefaultCloseOperation and getDefaultCloseOperation methods provided by JFrame, JInternalFrame, and JDialog use these constants. For examples of setting the default window-closing operation, see Responding to Window-Closing Events, a section in The Java Tutorial.
