      Hi and welcome to devnet,

      What version is it ?
      What OS are you running ?
      What compiler are you using ?

      One side note, it's Qt, QT stands for Apple QuickTime which is not what you are interested in.

          Is it as default project ?

          Beside the warnings there, can you build it ?
          From the looks of it, it could be the code model acting up.
