通过单击按钮最小化 PyQt5 应用程序

Question

我找到了一些关于如何将 pyqt 小部件最小化到系统托盘的材料，但我没有找到我需要的东西。

我想在单击按钮时最小化一个小部件，我不想覆盖默认关闭按钮，当人们单击窗口边框关闭时，它仍然会关闭，但是当它单击我的按钮时，它将最小化到系统托盘.

这是否可能，因为所有示例都试图覆盖默认事件。 我附加的这段代码是在 qtDesigner 中创建的，它只有一个按钮，有点像游乐场，我希望有人能帮忙，干杯。

Qt Designer创建一个类，用来填充另一个widget，它不是widget，所以建议创建一个类，继承相应的widget，使用Ui_Form类填充。欲了解更多信息，请阅读以下内容：

切入正题，必须使用showMinimized() 方法。
