python - Pyside-从另一个类添加小部件

Question

我正在尝试使用 PySide 构建布局，我遇到了一种情况，我想将一个小部件组保留在一个单独的类中并动态调用它。我查看了这个网站上的几个例子，这给了我一个想法，但我仍然无法自己解决这个问题。这是我正在构建的布局的示例代码，如果有人可以帮助我解决这个问题，这将非常有帮助。-提前致谢

我看到的一个错误是，您将 tab1 的第一个参数指向 calldisplay，我猜这是您要设置的小部件，但是您将它作为参数传递给“argument”，它是一个字符串，所以第一个更改是改变它。

另一方面，如果您要使用布局，请忘记 setGeometry()，因为现在几何由 QLayouts 处理。

最后，您的 display_elements 类未正确实现，因为 rgroup 未添加到小部件中，为此您必须使用布局。

考虑到上述情况，解决方案如下：

import PySide2.QtCore as QtCore

        tabWidget = QtGuiWidgets.QTabWidget()
        tabWidget.addTab(tab1(calldisplay), "tab1")
        tabWidget.addTab(tab2(argument), "tab2")
