get sizer for StaticBox

[John Lane]

I'm using a static box and static box sizer. I think I'm using the
correct pattern:

box = wx.StaticBox(self.content, id, name = name)
sizer = wx.StaticBoxSizer(box, orient = wx.VERTICAL)
self.content_sizer.Add(sizer, flag=wx.EXPAND)

I can then proceed to populate the box, for example:

sizer.Add(wx.StaticText(box, wx.ID_ANY, name='foo'))

Everything to this point works just fine.

Now, at some point later in the program, I need to add some more stuff
inside the static box. I can find the box:

box = next((b for b in self.content.GetChildren() if b.GetName() ==
some_name), None)

But I cannot get the sizer. I tried

sizer = box.GetSizer()

but it returns None.

How, given a StaticBox, can I get its sizer ?

Hi,

Which version of wxPython?

Thank you.

You need to use GetContainingSizer() because this sizer actually contains
both the static box and the other windows appearing inside it (but which
are actually box's siblings, not children).

Thanks, I worked that out myself a few hours after posing the question.
I do find the relationship between widgets and sizers confusing at times!
