从主 window 调用子 window

Question

我有一个 class 将成为我的校长 window。它被称为main_windows。在主 window 中，当我单击按钮 button_1 时，程序将打开另一个 GUI，使用户能够输入执行加法过程所需的值。 GUI 的模块称为 sub_windows，它位于另一个文件中。

我已经创建了一个名为 Model 的 class，因此它将是我的 class，用于计算期间所需的所有实例。

我如何调用模块 sub_windows 这是一个 GUI，同时将 class Model 发送到模块。

下面是代码：

模块main_windows:

Answer 1

如果你愿意，你可以把你的子 windows 变成 wx.Dialog。然后在你用来打开子 window 的事件处理程序中，你可以以模态方式打开对话框，这样它就会阻塞主 window。这将允许用户输入他们的数据并按下提交按钮或其他任何按钮。

按下提交按钮后，控件将切换回主 window 中的事件处理程序。您可以在那里提取用户输入的值：

def open_sub_window(self, event):
    dlg = subwindow(*args)
    dlg.ShowModal()
    # get the values
    value_one = dlg.text_ctrl_1.GetValue()

或者，您也可以使用 pubsub 在类之间发送数据。我个人更喜欢这种方法，因为它更灵活一些。您可以在以下链接中了解它的工作原理：
