我不太确定如何在使用QtDesigner设置的网格中显示自定义的小部件，如果您能以这种方式设置我的代码有什么不妥，并向我解释，将不胜感激。为什么我不能那样做。
我试图从创建的功能中添加小部件以导入我的小部件，但是效果不佳。在下面执行以下代码也不起作用。我不确定如何将小部件添加到我的网格并将我的网格设置为父网格，同时将新的小部件设置为子小部件。

我希望我的窗口小部件（这是一个运行的日期和时间时钟）出现在网格中，因为我将在要创建的其他窗口中使用该窗口小部件，并想知道如何将其应用于其他窗口。我试图运行以下代码，但错误exit code -1073740791 (0xC0000409)不断出现。
我不确定是否没有看到Ui_widget_currentDat_digitalClock的代码，但我怀疑这
pyuic生成的输出不应用作代码的基础。实际上，应该将它单独放置，主要是因为您可能需要在某个时候更改GUI，这使得将新代码与之前编辑的现有代码集成起来非常困难。
