我正在使用 wxWidgets (wxPython) 为我的 python 项目构建 GUI。有一个小但烦人的问题我似乎无法弄清楚。开始、交叉和浏览这三个按钮应该位于窗口的底部。这些是 wx.ToggleButton 小部件，它们属于水平 BoxSizer，而后者又是名为 leftmost_box 的垂直 。
问题是，如何将这些按钮强制向下移动到最左角？我尝试设置标志，即 BoxSizer 的子级wx.ALIGN_BOTTOM，但它不起作用。
同时附上源代码。

最佳答案
大小调整器中的比例值到处都是，在某种程度上标志条目也是如此。
- 清理
比例值 - 添加“NEXT”和“BACK”按钮(您忘记将它们添加到 sizer 中)
- 向
leftmost_box添加一个虚拟项目，比例为 1(以强制最终项目位于底部) - 将
leftmost_box添加到主 sizer 时设置 EXPAND 标志
我认为仅此而已。
