[提问]菜鸟请教：QWidgetFactory::create()无法弹出Dynamic Dialog [复制链接]

QT自带的例程，源程序如下：
void MainForm::creditDialog()
{
       Receiver *receiver=new Receiver;
       QDialog *creditForm=(QDialog *) QWidgetFactory::create("../credit/creditformbase.ui",receiver);
       receiver->setParent(creditForm);
       if (creditForm->exec())
       {
              QSpinBox *amount=(QSpinBox *) creditForm->child("amountSpinBox","QSpinBox");
              if (amount)
                   ratingTextLabel->setText(amount->text());
        }
        delete receiver;
        delete creditForm;
}
这是MainForm里的slot函数，编译能通过，可是运行的时候，只要click  MainForm的signal pushbutton,MainForm就退出了，根本无法调出"../credit/creditformbase.ui",到底是为什么啊？

就这个问题纠结了几天了，求高人耐心点拨一下，不甚感激！！！

代码提供的太少了,,不清楚问题出在哪里,自已加断点,试试走到了哪一步.

是不是路径不对啊？:create("../credit/creditformbase.ui",receiver);
用绝对路径试试

试过用绝对路径，但是用绝对路径的话，编译完成后运行应用程序，只要click连接该slot的button,电脑就死机了。反正就是无法弹出要调用的dialog.
