c++ - How to befriend QEventLoop and winapi event loop -


i have myapp class winapi event loop in it

class myapp : public qobject {     q_object public:     int winapi exec() {         msg msg;         int nretval;         while ((nretval = ::getmessage(&msg, nullptr, 0, 0)) != 0 && nretval != -1) {             ::translatemessage(&msg);             ::dispatchmessage(&msg);         }         return msg.wparam;     } };

when start program, qobject's events won't process (can't invoke slot , hence send signals).
somewhere on internet found kind of solution - create qapplication object, somehow "hooks up" winapi message loop , worked:

int main(int _argc, char* _argv[]) {     qapplication qa(_argc,_argv);     unreferenced_parameter(qa);      myapp mapp();     return mapp.exec(); }

but seems me design fragile , hack. , don't i'm using undocumented feature , never call qapplication.exec() method.
can tell me how right way? namely, want call 1 exec method (i guess 1 of qapplication, should put winapi loop?)
help

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
