How do you hide a wx.StaticBoxSizer and its contents?

[David Hughes]

I have got a wx.StaticBoxSizer that contains a list and a couple of buttons. The sizer does its job and defines the group nicely by drawing a box round the group and labels it. I can hide the individual controls inside the sizer but can't hit on the right incantation for hiding the sizer box itself. Is there one or should I put everything on a panel and hide/show that?

>>>self.sbsz
<wx._core.StaticBoxSizer; proxy of <Swig Object of type 'wxStaticBoxSizer *' at 0x70e0460> >
>>>dir(self.sbsz)
['Add', 'AddF', 'AddItem',.... 'Hide',..... 'Show'.......]

Hi David,

What about just hiding the wx.StaticBox instance? The sizer can not be
hidden as it is never really shown.

Or do I understand you not correctly?

If you put the StaticBox etc on a Panel, then you should be able to hide
it all by 'just' hiding the panel.

The StaticBoxSizer (or Stationmaster as my spell checker want to call it) draws a box around the controls inside it and optionally displays a label,  so I would like to hide these as well otherwise I am left with (in my case) quite a large empty box.

self.stbz.Hide()
Traceback (most recent call last):
  File "<string>", line 1, in <fragment>
TypeError: Hide() takes at least 2 arguments (1 given)

I assume the 1 argument is self, but what else is it expecting?

II was hoping to avoid the hassle of using panels but I'll do that if necessary.

The item for which that sizer is managing the size.  E.g.

self.stbz.Hide(panel5)

self.stbze.Layout()   # or is it Layout() on the parent widget?  I am not sure/haven't tried it.  I'd guess sizer in this case...?

Here's the docs text for sizer.Show(), for which sizer.Hide() is a convenience method of, equal to Show(show=False):

Shows or hides an item managed by the sizer. To make a sizer item disappear or reappear, use Show followed by Layout. The item parameter can be either a window, a sizer, or the zero-based index of the item. Use the recursive parameter to show or hide an item in a subsizer. Returns True if the item was found.

As I understand it, now for using StaticBox, you should make the StaticBox the parent of the widgets shown within the box (it used to be, prior to wxPython 2.9, you'd make the items shown in it siblings of the staticBox, but not now).  Then, if you call my_static_box.Hide(), it should, I think, hide all the widgets within it... I'd at least try that, if you make sure they are children of the static box.

Hi,
i believe, the first argument of Hide(...) is the the item, that
should be hidden; one would call Hide( ) on some higher-order sizer,
possible using recursive=True

Would e.g. the following work for you?
self.Sizer.Hide(self.stbz, recursive=True)
(assumming self is a frame or a panel which has a sizer asigned -
higher than self.stbz, in the same sizer hierarchy).

hth,

A sizer is not a wx.Window subclass, so you can't hide or show it. The hide and show methods it has require a wx.Window to be passed, as it's simply a helper function that calls the hide or show of the passed item.

Since the staticbox should be the other widgets' parent, you should be able to hide just that.

Hi David,

It seems also to depend on wxPython version.

If I use Phoenix then both button handlers work for me, if I use 2.8 then only the second one works.  I guess that makes sense as under 2.8 the items in the staticbox are siblings of it and not children.

The Phoenix method of creating a staticbox/sizer should work as of 2.9 but I couldn't make it work in my little test I attach.

I am using 2.9 and unable to to get it to work. It turns out though that
in the situation where I thought the controls in the box sizer were not
needed there is one case where they are, so I have to keep it visible
anyway.

Thanks to all for your replies.

Just out of curiosity:  what happened when you called .Hide() on the StaticBox (not the StaticBoxSIZER, but the StaticBox itself) that was the parent of the widgets within it?

I don't know what my problem was the other day (got some exception with
2.9), obviously must have done something wrong then.

With the attached code version 2.9 and 3 Phoenix work the same, hiding
the sizer or the staticbox will hide all, in 2.8 only hiding the sizer
will hide it all.

First, apologies for the late response. You are right and my original
understanding was incorrect. I had been using wxDesigner, which only
provides mention of wx.StaticBoxSizer, but looking at the code it
generates, I see:

box = wx.StaticBox( parent, -1, u"Box title" )
sizer = wx.StaticBoxSizer( box, wx.HORIZONTAL)

So, only having a reference to the sizer, I needed to do

sizer.GetStaticBox().Hide()

to achieve the right result.
