根据来自 QComboBox 的用户输入添加和删除动态生成的 QLineEdit 小部件
Adding and removing dynamically generated QLineEdit widgets based off of user input from a QComboBox
我正在构建一个应用程序以 'roll' 同一面的多个骰子，所以如果我需要滚动 5 个 8 面骰子我 select 5 在标签 D8 下的 QComboBox 中，然后弹出 5 个 QLineEdit 小部件，其中显示了 5 'die rolls' 的值。
目前，在 QComboBox 中的数字被 selected 后，我能够显示正确数量的 QLineEdit 小部件。当我尝试完全删除骰子滚动显示或将 QLineEdit 小部件的数量设置为小于第一个值集时，问题就来了。有时它会起作用，但从来没有当我尝试将显示设置为 0 时，其他时候我会抛出 KeyError 或 RuntimeError。

我已经尝试了几种不同的方法来删除小部件并最终得到不同的结果，只删除了所有其他显示，所有内容，每三分之一...等等。这是迄今为止我发现的最一致的方式。
我正在使用 python 3 和 pyside 2，我会担心在显示器正常工作后如何处理掷骰子。
如果您想从布局中删除小部件，您只需使用 deleteLater，但这并不意味着如果引用存储在列表中，它们将被删除。在我的策略中，我使用 deleteLater 消除了所有 QLineEdits，我重置了存储它的列表并创建了新的 QLineEdits。
