注意：如果无法做到这一点，那么是否可以在不更改完整代码的情况下使用QStackedLayout创建页面？怎么样？
我在PyQt4中创建了一个Quiz应用程序，由于这个问题，它很无组织，例如：
答案功能不正确，答案功能正确，超时功能正常，问题1每隔12秒就会调出超时。
我在Question1函数中添加了心（HP）：Heart，Heart1，Heart2，这是在Timeout之前，错误和正确的函数。
每当用户按下错误答案时，它将执行boolean：
if self.heart2.isHidden():
self.heart1.hide()
heartlosscount.append(1)
if self.heart1.isHidden():
self.heart.hide()
heartlosscount.append(2)
else:
self.heart2.hide()
heartlosscount.append(3)
我几乎没有显示按钮等的东西（它们都在功能中列出）
现在我决定将这个添加到Timeout功能上，这个功能不顺利，继续按钮不显示，Go back按钮不会显示，也不会显示心脏。
所以这是超级无组织的地方，我添加了Continue1，Goback1，Heart3，Heart4和Heart5。
不仅是Timeout，它甚至不会显示在正确的答案功能上，所以我也有不同的添加。
但是在视觉上不可能修改它们，因为如果在2个心中错误地回答错误，在第二个问题上，如果他们在Timeout上失败，他们将再次拥有2颗心，因为心脏不同定义即可。然而，不可能为此设置布尔值，所以如果heart1被隐藏，那么heart3也是一样，因为它们需要被执行所以程序知道它已被定义。
但最后，我只是隐藏了Timeout图片，（它是1280 x 800，背景图片），我看到了那些心和按钮。
如何使用 widget2 覆盖 widget1 或使 widget1 为 widget1 的父级？
因此它可以在widget1上显示widget2。
