Hi, I have an application that consists of a main frame, and then when i press a button another frame opens. Now, I have a problem. When i close the second frame that's opened from the first one, it causes both frames to close. Do you have any idea how to avoid that? I mean, when i close the second frame, i want to close just it, not the main one as well.
Don't use EXIT_ON_CLOSE as the default close operation but DISPOSE_ON_CLOSE instead. EXIT_ON_CLOSE causes System.exit to be closed, which will terminate the entire JVM. DISPOSE_ON_CLOSE only disposes (closes) the frame itself.
