如何解决QT中跳转第二个页面时闪退问题

 场景

        在当前页面MySenderPage，点击PushButton，跳转至MyReceivePage，通常会用到信号和槽实现

connect(button, &QPushButton::clicked, this, &MySenderPage::goToReceivePage);void MySenderPage::goToReceivePage()
{//另一个页面展示MyReceivePage w;w.show();this->hide();
}

        如果跳转页面使用 MyReceivePage w; w.show(); 会出现页面闪退的情况

解决方法

初始化页面使用指针就可以解决这个问题，MyReceivePage *w = new MyReceivePage; w->show();

connect(button, &QPushButton::clicked, this, &MySenderPage::goToReceivePage);void MySenderPage::goToReceivePage()
{//使用指针MyReceivePage *w = new MyReceivePage;w->show();this->hide();
}

完美解决
