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.

JFrame.setDefaultCloseOperation(int), JDialog.setDefaultCloseOperation(int), JInternalFrame.setDefaultCloseOperation(int)



static final int DO_NOTHING_ON_CLOSE

The do-nothing default window close operation.


static final int HIDE_ON_CLOSE

The hide-window default window close operation


static final int DISPOSE_ON_CLOSE

The dispose-window default window close operation.

Note: When the last displayable window within the Java virtual machine (VM) is disposed of, the VM may terminate. See AWT Threading Issues for more information.

static final int EXIT_ON_CLOSE

The exit application default window close operation. Attempting to set this on Windows that support this, such as JFrame, may throw a SecurityException based on the SecurityManager. It is recommended you only use this in an application.
