[wxpython] StaticBoxSizer problems

[Matthias Kluwe]

Hi!

I'd like to place several StaticBoxes in a frame, but I can't get it
right.

Consider the following code:

import wx

app = wx.PySimpleApp()
frame = wx.Frame(parent=None, title="Test")
box = wx.BoxSizer(wx.VERTICAL)
frame.SetSizer(box)
upper_box = wx.StaticBox(parent=frame, label="Upper Box")
box.Add(item=upper_box, flag=wx.GROW)
upper_sizer = wx.StaticBoxSizer(upper_box)
upper_sizer.Add(wx.Button(parent=frame, label="Button"))
frame.Show()
app.MainLoop()

This should show a frame containing a StaticBox which contains a
button, but: The button is not placed within the StaticBox. Hmm.

Additionally: wx.StaticBoxSizer.__init__.__doc__ says that a
StaticBoxSizer is created by __init__(self, StaticBox box, int
orient=HORIZONTAL). But if I change the line

upper_sizer = wx.StaticBoxSizer(upper_box)

to

upper_sizer = wx.StaticBoxSizer(StaticBox=upper_box)

I get the error: TypeError: new_StaticBoxSizer() takes at least 1
argument (0 given).

What am I missing?

Regards,
Matthias

You should remiove this line.
upper_sizer = wx.StaticBoxSizer(upper_box)
upper_sizer.Add(wx.Button(parent=frame, label="Button"))
frame.Show()
app.MainLoop()

Generally speaking what you appear to be missing is a methodical
approach to GUI consruction. This reminds me of a lot of my early
experiments with wxPython code :-)

Less is more, but it *does* take a while to get the hang of sizers and
the like.

Hmm. As I see it, this means constructing the StaticBox and not placing
it in the frame. Obviously, this does not help.

"a methodical approach to GUI construction"? Please be more specific --
any hints are welcome. Clearly, the above is an experiment with
wxPython, not anything methodical. This may follow when I understand
how StaticBoxSizer works.

Hi!

If anybody's interested, I've got an solution now.

I'd like to place several StaticBoxes in a frame, but I can't get it
right. import wx app = wx.PySimpleApp()
frame = wx.Frame(parent=None, title="Test")
box = wx.BoxSizer(wx.VERTICAL)
frame.SetSizer(box)
upper_box = wx.StaticBox(parent=frame, label="Upper Box")
box.Add(item=upper_box, flag=wx.GROW)
upper_sizer = wx.StaticBoxSizer(upper_box)
Oops. That's a thinko. upper_box is no sizer. The right line must be

box.Add(item=upper_sizer, flag=wx.GROW)
upper_sizer.Add(wx.Button(parent=frame, label="Button"))
frame.Show()
app.MainLoop() [...] Additionally: wx.StaticBoxSizer.__init__.__doc__ says that a
StaticBoxSizer is created by __init__(self, StaticBox box, int
orient=HORIZONTAL). But if I change the line upper_sizer = wx.StaticBoxSizer(upper_box) to upper_sizer = wx.StaticBoxSizer(StaticBox=upper_box) I get the error: TypeError: new_StaticBoxSizer() takes at least 1
argument (0 given).

This is still to be solved.

Regards,
Matthias

Did you actually try removing the line and running the program? Guess
what: the button appears inside the static box sizer. And your problem
with that would be ... ?

Well, "methodical" would seem to include testing the suggestions of
well-meaning fellow netizens, for a start, rather than using your
psychic powers to predict results.

I tried, of course :-) Removing the line

box.Add(item=upper_box, flag=wx.GROW)

yields the remaining program

import wx

app = wx.PySimpleApp()
frame = wx.Frame(parent=None, title="Test")
box = wx.BoxSizer(wx.VERTICAL)
frame.SetSizer(box)
upper_box = wx.StaticBox(parent=frame, label="Upper Box")
upper_sizer = wx.StaticBoxSizer(upper_box)
upper_sizer.Add(wx.Button(parent=frame, label="Button"))
frame.Show()
app.MainLoop()

.... the StaticBox not being displayed.

No prediction needed :-) I can't see how I have suggested you're not
well-meaning.

But the StaticBox *is* displayed when I run the program under Windows,
at least. What platform are you running on?"a methodical approach to GUI construction"? Please be more specific --

I didn't take any such inference from your response. I am slightly
confused that the program doesn't run for you, however. Here's the exact
source I ran:

import wx

app = wx.PySimpleApp()
frame = wx.Frame(parent=None, title="Test")
box = wx.BoxSizer(wx.VERTICAL)
frame.SetSizer(box)
upper_box = wx.StaticBox(parent=frame, label="Upper Box")
#box.Add(item=upper_box, flag=wx.GROW)
upper_sizer = wx.StaticBoxSizer(upper_box)
upper_sizer.Add(wx.Button(parent=frame, label="Button"))
box.Add(upper_sizer, flag=wx.GROW)
frame.Show()
print "running"
app.MainLoop()

The upper_box is displayed because it's presented as an argument to the
StaticBoxSizer's creator.

Steve
