Java Forum / General / May 2006HowTo exit from an application
I have an application that use awt and Swing, with this code : public void windowClosing(WindowEvent e) { Window window = e.getWindow(); if (window.equals(this)) { setVisible(false); dispose(); } } But when I close it some resources remain occuped and I can have prompt until I press CTRL C. Why ? _____ Flex >I have an application that use awt and Swing, with this code : > [quoted text clipped - 8 lines] > But when I close it some resources remain occuped and I can have prompt > until I press CTRL C. Why ? The easiest way to get your program to quit when you close the window is to use the setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); - Oliver Il Fri, 05 May 2006 16:33:52 +0000, Oliver Wong ha scritto: > The easiest way to get your program to quit when you close the window is to > use the setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); It's the same, I don't understand why, but something remains open.. ____ FleX > Il Fri, 05 May 2006 16:33:52 +0000, Oliver Wong ha scritto: > [quoted text clipped - 3 lines] > > It's the same, I don't understand why, but something remains open.. Can you post an SSCCE demonstrating the problem? http://mindprod.com/jgloss/sscce.html - Oliver Il Fri, 05 May 2006 22:11:11 +0000, Oliver Wong ha scritto: > Can you post an SSCCE demonstrating the problem? > http://mindprod.com/jgloss/sscce.html it'is not simple, because this is a big application, with some class, I need a method to understand what remains open after exit. ___ FleX > Il Fri, 05 May 2006 22:11:11 +0000, Oliver Wong ha scritto: > > it'is not simple, because this is a big application, with some class, I > need a method to understand what remains open after exit. What about having an observer that all the windows notify when they open or close, and so the observer always has an accurate list of the open windows, and can exit as appropriate? - Oliver Il Mon, 08 May 2006 14:00:57 +0000, Oliver Wong ha scritto: > What about having an observer that all the windows notify when they open > or close, and so the observer always has an accurate list of the open > windows, and can exit as appropriate? it's strange, when I try to run the application in debug mode (with Netbeans) i receive this error : Listening on 55850 User program running Breakpoint hit at line 497 in class java.lang.Integer by thread main. Thread main stopped at Integer.java:497. and the application doesn't run. ____ FleX > Il Mon, 08 May 2006 14:00:57 +0000, Oliver Wong ha scritto: > [quoted text clipped - 9 lines] > Breakpoint hit at line 497 in class java.lang.Integer by thread main. > Thread main stopped at Integer.java:497. Remove the breakpoint, or press continue on the debugger. - Oliver > But when I close it some resources remain occuped and I can have prompt > until I press CTRL C. Why ? Like, command prompt? Well if run your program from command prompt (like "java MyClass") of course then it will return to wherever it started from... and that's command prompt. If not, you didn't close the "main" thread (like JFrame thing Oliver suggested) or have some other thread running. -- Kova Il Sat, 06 May 2006 20:37:42 +0200, Kova ha scritto: > Like, command prompt?

I run the GUI program from a x-terminal and when I close it, javaVM remain in memory, but I cannot understand why.. _____ FleX > Il Sat, 06 May 2006 20:37:42 +0200, Kova ha scritto: > [quoted text clipped - 9 lines] > _____ > FleX Have you tried adding System.exit(0); ???
