You can't sort the sizer items in place. It would be possible to write your own function for doing this, of course, but it would use <code>wxSizer::Detach()</code> and <code>Insert()</code> under the hood anyhow.

blocks|key|40981|text|所以我发现分离方法就是我要找的！我仍然想知道一种方法来排序一个sizer的项目列表，而不是分离所有的项目，然后再附加一个子列表。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|40982|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

So I found out that the detach method is what I'm looking for! I would still be interested to know of a way to sort a sizer's item list though, without detaching all of the items and then re attaching a sublist.

blocks|key|3798368|text|您应该能够调用sizer的父级的布局方法，这将使它重新计算显示的项。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3798369|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

You should be able to call the Layout method on the parent of the sizer, this will make it recalculate the shown items.

Getting the buttons to sort is a little tricky, but the key is finding something to sort by. You could use the button label or the button name. I went with the latter. The following code also demonstrates how to show/hide buttons:

 hSizer = wx.BoxSizer(wx.HORIZONTAL)

 for item in range(10):
 val = random.choice(range(10000,99999))
 label = "Button %s" % val
 name = "btn%s" % val
 btn = wx.Button(self, label=label, name=name)
 self.mainSizer.Add(btn, 0, wx.ALL|wx.CENTER, 5)

 toggleBtn = wx.Button(self, label="Hide/Show Some Buttons")
 toggleBtn.Bind(wx.EVT_BUTTON, self.onHideShow)
 hSizer.Add(toggleBtn, 0, wx.ALL, 5)

 sortBtn = wx.Button(self, label="Sort buttons")
 sortBtn.Bind(wx.EVT_BUTTON, self.onSort)

I have a wxpython grid sizer that is sizing sublists of bitmap buttons. The master list I would like to create just once because creating these buttons takes a considerable amount of time, and thus I do not want to destroy them. My idea is to somehow remove all of the buttons from the sizer, make a new list of the buttons that I want the sizer to contain, and then use the sizer's AddMany method.

If I can't remove the buttons from the sizer without destroying them, then is there a way to use the sizer's Show method to hide some of the times, but then have the sizer adjust to fill in the gaps? When I hide them, all I can get them to do right now is just to have them disappear and leave a gap. I need the next item to be adjusted to the gap's place.

Also is there a way to sort the grid sizer's item list?

Thanks for any help you can offer.

How to either sort a wxsizer or remove items without destroying them?

我有一个wxpython网格sizer，用于调整位图按钮的子列表。我只想创建一次主列表，因为创建这些按钮需要相当长的时间，因此我不想销毁它们。我的想法是以某种方式从sizer中删除所有的按钮，为我希望sizer包含的按钮创建一个新的列表，然后使用sizer的AddMany方法。如果我不能在没有销毁的情况下从屏幕上移除按钮，那么是否有一种方法可以使用sizer的some来隐藏一些时间，然后让size
