我是一个新手，开始在wxpython上为一个班级项目工作。你知道吗

主机有一个辅助笔记本。Auinotebook由Choicebook面板制成。每个Choicebook面板由12个textctrl变量组成。你知道吗

如果用户更改了一个Choicebook面板中的值，我也需要更改其他Choicebook面板中相应的值。你知道吗

这些值在数学上是相关的。我无法更新其他面板的值。你知道吗

任何关于这方面的帮助都会很好。你知道吗

谢谢你抽出时间来帮我。你知道吗

Answer 1

您已经正确地开始将EVT\u TEXT\u ENTER绑定到UpdateEstValues。这样就得到了输入的值，唯一需要做的就是将这个值转移到第二个选项卡中，对吗？您似乎还将解析器用作保持当前有效值正确的“模型”？因此，在UpdateEstValues中，您可以更新模型（解析器），您可以让它自己工作，您只需要告诉第二个选项卡更新它的值。你知道吗

从结构上讲，有很多方法可以做到这一点，但归根结底都是触发一个事件，通知第二个选项卡进行更新。所以最基本的想法是有一个函数语法分析器.fire以及parser.add\u侦听器. 第二个选项卡将有一个函数更新

def update(self, parameter_name):
    self.text_edits[parameter_name].SetValue(parser.get_value("parameter_name"))

在创建选项卡后的主框架中，您将执行以下操作：

parser.add_listener(second_tab.update)

在UpdateEstValues中，您将执行以下操作：

parser.fire(parameter_name)

我们缺少：

def add_listener(self, listener):
    self.listeners.append(listener)

def fire(self, parameter_name):
    for i in self.listeners:
        i(parameter_name)

这当然是一种方法的最小演示。可以查找pubsub包，也可以使用wx事件（用户定义）通知第二个选项卡的更改，但原则上它们都是相似的。你知道吗
