Qt closing tray icon after application stops

Question

I've a little problem with tray icon under windows. After my Qt application stopps (normal exit) the icon still remains in system bar. It disapears only when I move mouse cursor over it. I tried to hide it in the destructor of my window but it fails: I tried .setVisible(false).

Any ideas? Thanks.

P.S. I remember I had the same problem with SWT/Java.

why would you call `setVisible(false)` rather than just destroying the widget? — David Heffernan, Mar 27 '11 at 13:34
@David: I used setVisible(false) because this function couses trayicon to disappear. AFAIK qt will destroy the widget anyway. And I tried to destroy traicon with delete operator. — Sebastian Dusza, Mar 27 '11 at 16:24
@atamanroman: Normal exit. I press the [x] button in the window header. — Sebastian Dusza, Mar 27 '11 at 16:25

I wouldn't hide it in the destructor. It will likely be an invalid reference at that point. I would put it in where your event for "Exit" happens.

Good idea :) I reimplemented closeEvent member function and called setVisible(false) to hide the icon before exit. – Sebastian Dusza Mar 27 '11 at 22:04

If you're not able to call it from a destructor, you could connect the QCoreApplication::aboutToQuit() signal to the QSystemTrayIcon::hide() slot.
