Is there any event when using "alt+tap" or "swipe gesture" to switch to other app from mine, except 'onblur'?

Question

Hi,

I want to do something when  using "alt+tap" or "swipe gesture" to switch to other app from mine. I try window.onblur event.

But when I click 'Settings' or other buttons on 'Charm', 'onblur' event is fired which I do not expect.

Answer 1

What exactly are you trying to do when the focus goes away from your app to another app? Are you trying to save "state" of your app when some other app comes to the foreground? If you are trying to save the state when your app is being suspended, then there are better ways of doing this - such as registering for the checkpoint event and then saving the data. If that's the case then the following link should help: http://msdn.microsoft.com/en-us/library/windows/apps/hh465138.aspx If not, please clarify what exactly is the end goal of registering for the onblur event.

Thanks,

Prashant

Hi,

I try to stop a playing video in my app when the focus goes away from my app. The 'onsuspended' event will be fired after 10 seconds when I switch to another app from mine. It is a little late. And if I use 'onblur' event, when I click a button on Charm, the video will be paused which I do not expect.

I find document.onmsvisibilitychange event that I can use.
