选择按钮并打开其他按钮并重置pyqt5中的其他按钮

Question

我有一个Pyqt5 GUI，它使用UDP流显示视频

有些按钮可以激活某些按钮如（SD1或SD2或SD3将激活TP1和TP2）并且源1将激活TP5和TP6，依此类推

单击SD1之后，TP1和TP2将处于活动状态，如果单击TP1，它将在右侧显示带有程序名称的特定UDP流。

但是当我尝试单击另一个SD或Source时，我希望按钮的状态恢复为原来的状态，而视频要停止并重置所有按钮，因此我没有同时单击并启用许多按钮。

这里是代码：

如果一次只希望检查一个按钮，则可以使用QButtonGroup来管理每个按钮的状态。默认情况下，按钮组是排他的，因此您只需要添加按钮即可。

def __init__(self, parent=None):
    . . .
    group = QtWidgets.QButtonGroup(self)
    for btn in [self.EspSD, self.DeuSD, self.DeupSD, self.IntS, self.AstD, self.IntSdep]:
        group.addButton(btn)
