Hi, there! I wonder if I could create the main widget on heap in main()?
Following is my example code:
int main(int argc, char *argv[]){ QApplication app(argc, argv); QLabel
*label = new QLabel; label->show(); return app.exec();}
label should live longer than app so there might be unsafe because any
QPaintDevice must have a QApplication.I'm not sure am I right? That's all main
widgets should create on stack in main() in order to avoid such things? Or
there is no such requirement? If it should on stack, could you give me some
examples about the crash when created on heap?
Thank you!
