更新了wxPython之后，运行程序，发现以前OK的程序莫名报错了……
wx._core.wxAssertionError: C++ assertion “!(flags & wxALIGN_BOTTOM)” failed at …srccommonsizer.cpp(2136) in wxBoxSizer::DoInsert(): Vertical alignment flags are ignored in vertical sizers
python-baseException
老版本的wxPython能忽略类似这样的错误，但是4.1之后就不被忽略了……
对于我们这些使用wxFormBuilder的人来说…… 遇到了一点点小麻烦……
当我们改变了某个Sizer的wxVERTICAL或wxHORIZONTAL后，在运行时就会遇到类似的错误
但是~ 此时的wxFormBuilder界面的ToolBar上无法对报错的对齐属性进行编辑了……
下图：我遇到的报错是 m_staticText2 的 wxALIGN_BOTTOM 不能被使用于 Sizer 的 wxVERTICAL 模式下，我需要把它去掉，但无法快捷使用ToolBar上的按钮了。
只能这样做：
打开有问题的控件的属性页的最后一项：flag，把有问题的属性去掉即可。
另外，这样的问题，每执行一次只能找到一个。如果想批量找出来的话，就只能自己写段分析代码了。
原始的.fbp文件是xml格式的，可以分析每个sizer的下一层（注释1）里的控件是否flag属性里有冲突项。反正就是竖着放的Sizer下的控件不能有Align Top Button；横着放的Sizer下的控件不能有Align Left Right
注释1：不是XML的层，实际的XML中多了一层 sizeritem

然后会输出结果：(会显示整条有问题的Tree Name)
