[SOLVED]Capturing application sleep/wake in Qt

[DRoscoe]

My iOS application runs on an iPad and communicates via TCP/IP to an external server. When the user locks the iPad using the home key or through timeout, I lose my socket connection. My questions are:

1. Can I trap this event to properly suspend my processing?
2. Can I received notification of waking to try and re-establish communication?

I could get by with just a signal saying that we've just woken up. Then I could check for my connection status and initiate a connection if none is present.

Hi @DRoscoe,
Have a look at applicationState. Connect to applicationStateChanged signal to get notified about the changes.

@p3c0 Thank you! That did the trick!
