npyscreen addVisibleWhenSelected隐藏时清除值

Question

我对python还很陌生，我正在尝试用npyscreen来组装一个小应用程序。这个应用程序的一部分有一个带有FormControlBox的页面，选中该页面时会显示一个FormControlBox。选中第二个FormControlBox时，会显示一些文本字段。你知道吗

我遇到的问题是让第二个FormControlBox在第一个未选中时将其值更改为False（使第二个隐藏）。这是我在这个窗体类中尝试采用的方法。你知道吗

class envMenuForm(npyscreen.Form):
    def afterEditing(self):
        # Updating mapping with values set from form creation
        hostConfig["hostname"] = self.hostname.value
        hostConfig["domain"] = self.domain.value
        hostConfig["fqdn"] = self.fqdn.value
        self.parentApp.setNextForm('CEV')

    def create(self):
        # Defining vars from current baseConfig mapping from JSON file
        self.hostname = hostConfig["hostname"]
        self.domain = hostConfig["domain"]
        self.fqdn = hostConfig["fqdn"]

        # Adding text fields with the defaults from the config file
        self.hostname = self.add(npyscreen.TitleText, name = "System Hostname:", value = self.hostname)
        self.domain = self.add(npyscreen.TitleText, name = "System Domain:", value = self.domain)
        self.fqdn = self.add(npyscreen.TitleText, name = "System Fully Qualified Domain Name:", value = self.fqdn)

        self.et0status = self.add(npyscreen.FormControlCheckbox, name="Enable Eth0", value = False)
        self.et0type = self.add(npyscreen.FormControlCheckbox, name = "Configure as Static Address (ignore for DHCP)", value = False)
        self.et0ipaddress = self.add(npyscreen.TitleText, name = "IP Address", value = "127.0.0.1")

        self.et0status.addVisibleWhenSelected(self.et0type)
        self.et0type.addVisibleWhenSelected(self.et0ipaddress)

    def while_editing(self,arg):
        if arg is self.et0type:
            if arg.hidden:
                self.et0type.value = False

经过一系列重构之后，我能够利用adjust_widgets（）和一些后台逻辑来解决这个问题，以确保它不会触发太多。你知道吗
