我有一个名为StaticText的{{1}}列表。我想从text_Ani[]中删除其中一个（称为＆＃34; sizer＆＃34;）。
我尝试了两个选项，每个选项都删除了对象，但留下了一个空白区域，我想删除它。
我尝试过的选项是：
GridBagSizer
和
sizer.Hide(self.text_Ani[id])
sizer.Remove(self.text_Ani[id])
其中sizer.Detach(self.text_Ani[id])
self.text_Ani[id].Destroy()是主窗口的名称。
所有这些都接着是致电：
self
某些网站上建议的对self.panel.Layout()和wx.LayoutAlgorithm().LayoutWindow(self, self.panel)的额外通话似乎没有帮助。
总是留有空白。我如何摆脱空白？
编辑：这里的代码：
self.panel.Fit()答案 0 :(得分：1)
该代码不小，但它可以运行。我认为你有一个空白的主要原因是你根本没有递减self.iw。因此，您总是告诉您网格在不再存在的内容之后继续添加项目。我继续将self.iw-=3添加到remove_region方法的末尾来修复代码。我还在该方法中取消了一些内容，以使其更好地工作：
