I have the following SWT test code:
public static void main(String[] args) {
shell = new Shell();
shell.setText(APP_NAME + " " + APP_VERSION);
shell.addShellListener(new ShellListener() {
public void shellActivated(ShellEvent event) { }
public void shellClosed(ShellEvent event) { exit(); }
public void shellDeactivated(ShellEvent event) { }
public void shellDeiconified(ShellEvent event) { }
public void shellIconified(ShellEvent event) { }
});
shell.open();
display = shell.getDisplay();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
display.dispose();
}
My exit() method is as follows:
private void exit() {
System.exit(0);
}
I try to quit the application by closing the shell ("window") or by pulling down the application menu (labeled "SWT") and selecting "Quit".
When I do this, a SWT stub is left behind in the Dock and the SWT application has not actually exited. I have to manually terminate the SWT application through Eclipse or via Force Quit.
I have tried this with the v3.4 and v3.5 SWT jars, under Eclipse 3.4.1 under Mac OS X 10.5.6 (Intel).
Is there additional work I need to do to be able to quit the application when I close the shell?
You are not releasing the native resources correctly - you have a resource leak.
You don't need to do this:
private void exit() {
System.exit(0);
}
The main method will exit when the shell is disposed. If you must use an exit method, call it after you've disposed all SWT resources:
Display display = new Display();
try {
Shell shell = new Shell(display);
try {
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
} finally {
if (!shell.isDisposed()) {
shell.dispose();
}
}
} finally {
display.dispose();
}
System.exit(0);
