我有一个使用UDP流显示视频的Pyqt5图形用户界面

有一些按钮可以激活某些按钮(SD1或SD2或SD3将激活TP1和TP2)，源1将激活TP5和TP6，依此类推

单击SD1后，TP1和TP2将处于活动状态，如果我们单击TP1，它将在右侧显示某个UDP流，并显示该程序的名称。

但当我尝试单击另一个SD或信号源时，我喜欢将按钮的旧状态重置为重置，将视频停止并重置所有按钮，因此我不会同时单击和启用许多按钮。

代码如下：

如果您希望一次只选中一个按钮，则可以使用QButtonGroup来管理每个按钮的状态。默认情况下，按钮组是独占的，因此您只需添加按钮即可。

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)
