Interface WindowConstants

All Known Implementing Classes:
  JDialog, JFrame, JInternalFrame

public interface WindowConstants

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.

Field Summary
`static int` | `DISPOSE_ON_CLOSE` The dispose-window default window close operation
`static int` | `DO_NOTHING_ON_CLOSE` The do-nothing default window close operation
`static int` | `EXIT_ON_CLOSE` The exit application default window close operation.
`static int` | `HIDE_ON_CLOSE` The hide-window default window close operation
