Question

我是Python的新手，虽然我已经有很多年了。其他语言的经验。我遇到的主要问题是Sizer。仅使用BoxSizer我已经设法让事情按预期工作。然而，当我合并GridBagSizer时，我发现我只能水平拉伸窗口而不是垂直拉伸窗口。我搜索过以前的查询但没找到任何与我的问题完全匹配的内容。

我已陷入困境超过一天，所以提前感谢任何回复......

App和Frame的代码是： -

        self.main.Show()
        self.SetTopWindow(self.main)

    application = BoaApp(0)
    application.MainLoop()

Answer 1

改变这个：

self.boxSizer1.Add(self.gridBagSizer1, 0, wx.ALL|wx.EXPAND)

为：

self.boxSizer1.Add(self.gridBagSizer1, 1, wx.ALL|wx.EXPAND)

以下是使用size_controls使用wxPython进行布局的另一种方法。我真的很喜欢它们，因为我现在很容易用它们来布局屏幕，而不是像Boa那样使用UI设计器（我很喜欢并过去使用过它）。

代码的一些注释，我使用了wxversion，因为我的机器上安装了一些wxPython版本，所以需要选择一个。
