在 wxPython 中编写联系表？

如何解决在 wxPython 中编写联系表？

我有一个代码。当它运行时，您单击添加联系人按钮并添加一些联系人。当您按下每个联系人时，它只会显示您添加的最后一个联系人信息。但是，当我按下每个联系人时，我希望它显示我单击的联系人的信息。谁能帮我解决这个问题？

解决方法

每个人在使用wxPython的时候都会发展出自己的风格。正如 Rolf 所建议的，您不仅要向框架添加小部件，还需要添加面板。我在下面添加了一个基本的联系人添加屏幕。 'New' 按钮创建一个 wx.Dialog 的实例，它捕获联系人的详细信息。然后这些可用于 MainFrame，您可以根据需要将它们保存在其中。

请注意，我在应用程序中自由创建了新类来处理不同的关注领域。 GUI 应用可能会变得非常复杂，在我看来，将每一点功能都分解到自己的方法或类中是无可替代的。

并非所有东西都需要成为框架类的成员。

还要注意，我使用了 sizers 而不是绝对位置。

此代码无法完成您想做的所有事情，但可能会帮助您入门。
