I call EnableVisibilityChangedEvents in my CAknAppUi by this: CEikonEnv::Static()->RootWin().EnableVisibilityChangeEvents(); but it always crashes. It this the correct way? I am doing this because I want to being notified of any screen visibility change. Note all other Enable* function calls work fine. (e.g. EnableFocusChangeEvents()) Thanks |

Isn't overriding HandleForegroundEventL() enough for you ? (see http://www.newlc.com/Moving-an-application-to.html)

Overriding HandleForegroundEventL is a good idea and I did that, but I end up testing for a lots of Uid inside my HandleForegroundEventL() function; as I want my app to quit when other apps (besides network APN dialog, help, bluetooth selection, etc etc) are in front of my app. so kind of like when a full screen app is in front of my app, i will quit, otherwise i won't.
