从主窗口调用子窗口

Question

我有一个将成为我主要窗口的课程。它被称为main_windows。在主窗口中，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添加过程所需的值。 GUI的模块名为sub_windows，它位于另一个文件中。

我已经创建了一个名为Model的类，因此在计算过程中它将成为我所需要的所有实例的类。

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

下面是代码：

模块main_windows：

Answer 1

如果需要，可以将子窗口设为[1, 2].min_by { |v| [v.abs, -v] } # => 1 [1, -1].min_by { |v| [v.abs, -v] } # => 1 。然后在用于打开子窗口的事件处理程序中，可以以模态方式打开对话框，以阻止主窗口。这将允许用户输入他们的数据并按下提交按钮或任何时候。

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

wx.Dialog

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。您可以通过以下链接了解它的工作原理：
