在pyqt5中选择按钮并打开其他按钮并重置其他按钮答案

【问题标题】：Select button and turn on others and reset other buttons in pyqt5在pyqt5中选择按钮并打开其他按钮并重置其他按钮

【问题描述】：

我有一个使用 UDP 流显示视频的 Pyqt5 GUI

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

点击 SD1 后，TP1 和 TP2 将被激活，如果我们点击 TP1，它将在右侧显示一个带有程序名称的特定 UDP 流。

但是当我尝试单击另一个 SD 或源时，我希望重置按钮的旧状态，停止视频并重置所有按钮，所以我没有同时点击和启用很多按钮。

代码如下：

【解决方案1】：

如果您希望一次只检查一个按钮，您可以使用 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)
