如何在PyQt5中刷新组框？

Question

我正在尝试刷新某个回调函数中的整个groupbox。你知道吗

这是我如何把窗口布局。你知道吗

self.setWindowTitle(self.title)
self.setGeometry(self.left, self.top, self.width, self.height)
self.GroupBox1 = self.createVialButtons()
self.GroupBox2 = self.createTable()

self.windowLayout = QVBoxLayout()
self.windowLayout.addWidget(self.GroupBox1)
self.windowLayout.addWidget(self.GroupBox2)
self.setLayout(self.windowLayout)

self.show()

在my callback中，我删除了原来的分组框，然后重新创建两个分组框，最后将这两个分组框添加到布局中。你知道吗

self.windowLayout.removeWidget(self.GroupBox1)
self.GroupBox1 = self.createVialButtons()
self.windowLayout.addWidget(self.GroupBox1)

self.windowLayout.removeWidget(self.GroupBox2)
self.GroupBox2 = self.createTable()
self.windowLayout.addWidget(self.GroupBox2)

它似乎工作，但组框标签似乎加起来每次我调用回调函数。你知道吗

我在网上搜索，发现有人使用update（）。然而，我不知道如何在我的情况下使用它。你知道吗

在这种情况下，有没有合适的方法来实现我想做的事情？你知道吗

此处提供了完整的工作代码：
