Re: Java Swing and
Po default windowa (JFrame-a) stava invisible. Za da promenish tova povedenie, izpolzvai setDefaultCloseOperation methoda. Eto mu i javadoca:
public void setDefaultCloseOperation(intoperation)
Sets the operation that will happen by default when the user initiates a "close" on this frame. You must specify one of the following choices:
DO_NOTHING_ON_CLOSE (defined in WindowConstants): Don't do anything; require the program to handle the operation in the windowClosing method of a
registered WindowListener object.
HIDE_ON_CLOSE (defined in WindowConstants): Automatically hide the frame after invoking any registered WindowListener objects.
DISPOSE_ON_CLOSE (defined in WindowConstants): Automatically hide and dispose the frame after invoking any registered WindowListener objects.
EXIT_ON_CLOSE (defined in JFrame): Exit the application using the System exit method. Use this only in applications.
The value is set to HIDE_ON_CLOSE by default.
