I have two Questions

  1. In my application I have created two screens first is “Home screen” & second is “Main screen” & I want to toggle between screens after every 1 minute. how can I do that? i tried with Loaded event option but it is not working .
  2. In my application I also want to use ZMQ to receive user data and display on the screen. I am able to use in GUI-Guider simulator but when i try to bitbake the meta layer it is generating error. even i have already given path in Cmakefile for ZMQ lib. plz guide
