需要向下滚动才能看到的对象不可见

Question

我使用wxpython来编写这个简单的表单。我使用的是带有滚动条和少量文本控件的笔记本。我可以看到屏幕上可以查看的小部件，但是需要向下滚动的小部件是不可见的。在下面的代码中，我可以看到＆＃34;输入日志＆＃34;对这些字段进行适当的文本控制，但缺少＆＃34;评论字段以及提交和取消按钮。

import wx

将wx.lib.filebrowsebutton导入为filebrowse

如果名称 ==＆＃34; 主要＆＃34;：     app = wx.App（）     框架（无）     app.MainLoop（）

Answer 1

将项目添加到sizer时，您始终将比例值设置为1，但self.sub_button除外。这是导致你的问题的原因。

inside_sizer_h9.Add(self.sub_button, wx.ALL, 5)    

应为：

inside_sizer_h9.Add(self.sub_button,1, wx.ALL, 5)

另请注意，发布的代码main不正确，应为：

if __name__ == "__main__":   

通过这些修改，您的代码应该在您编写时起作用。
