Hi all,
I checked the tray icon snippet for SWT application and try to add a
display of tray icon after my application window is closed... I put my
code in configureShell because the example used shell to create the tray
item. However it doesn't work...there is no error message. The
application ran and after I clicked on the close button on my app
window, the system tray didn't show up...I think the way I add listener
to the shell is wrong... Can anybody point me to the right direction?
Also I would like to know how to show the app window after a user double
click on the tray icon. Thank you in advance.
protected void configureShell(Shell newShell)
{
super.configureShell(newShell);
newShell.setText(Messages.getString("Example"));
newShell.addListener(SWT.Close, new Listener() {
public void handleEvent (Event event) {
final Tray tray = Display.getCurrent().getSystemTray ();
if (tray == null) {
System.out.println ("The system tray is not available");
} else {
final TrayItem item = new TrayItem (tray, SWT.NONE);
item.setToolTipText("My application");
item.addListener (SWT.Show, new Listener () {
public void handleEvent (Event event) {
System.out.println("show");
}
});

Hi Tom,
Thank you for your prompt response. You mean I should do something like
while (true) {}? Is there a standard way to make a System Tray Icon work
properly? I also want to bring back the app window after user click on
it... If you have come across this issue before, please tell me how to
bring back the app window. :) THX

This might sounds stupid but can do something like
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
to a tray item and how?

Hi,
yes that's what I mean you need to make the event loop handling yourself
else your application simply ends.
I've never worked with it but I think you should veto to close and
simply hide the shell and then unhide it when one clicks the tray icon.
Doing it this way you don't have to catch the event loop your own ;-)

Hi,
1. If you are running an RCP:
http://help.eclipse.org/help31/nftopic/org.eclipse.platform. doc.isv/reference/api/org/eclipse/ui/application/WorkbenchWi ndowAdvisor.html#preWindowShellClose()
2. If you have an SWT-Standalone application:
shell.addShellListener(new ShellAdapater() {
public void shellClosed(ShellEvent e) {
e.doit = false;
}
} );
3. ApplicationWindow:
Simply overload handleShellClose()

to control... I always have difficulty to find the correct shell or
display object to invoke my method on...
I added a listener to shell in configureShell to listen to the close
event. If the event is fired, a tray item will be created...
Then I try to stop the application window being disposed in
handleShellClose(). However it didn't work... seems like the window had
been disposed before this method was invoked...I got a null pointer
exception while double click on the tray item trying to bring the window
back.
Can anybody point me to the right direction?
