Center StaticText within a sizer

wxPython Users
1

Hi folks,

I'm trying to horizontally center the text of a wx.StaticText of given
size within a horizontal sizer, e.g. want to have a fixed sized
textbox with the text centered within.
The intuitive solution

class SomeFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, -1)
        panel = wx.Panel(self, -1, size = (400,400))
        text = wx.StaticText(panel, -1, "some text", size = (200,
100), style = wx.ALIGN_CENTER)
        sizer = wx.BoxSizer(wx.HORIZONTAL)
        sizer.Add(text,1,flag = wx.CENTER)
        self.SetSizer(sizer)

doesn't work at all (wx version 2.8.10).

I'm obviously missing something and I'd be glad if someone could point
me into the right direction,

thanks

A) send *complete* examples:

http://wiki.wxpython.org/MakingSampleApps

B) the source of you problem is that you are putting the StaticText on a Panel, but setting the sizer on the Frame (self.SetSizer). I try to avoid nesting panels like that in one class:

http://wiki.wxpython.org/wxPython%20Style%20Guide

Addresses this and other issues.

try somethign like (untested):

class SomeFrame(wx.Frame):
     def __init__(self):
         wx.Frame.__init__(self, None, -1)
         panel = wx.Panel(self, -1, size = (400,400))
         text = wx.StaticText(panel, -1, "some text", size = (200,
100), style = wx.ALIGN_CENTER)
         sizer = wx.BoxSizer(wx.HORIZONTAL)
         sizer.Add(text, 1, flag = wx.CENTER)
         panel.SetSizer(sizer)

Thanks Chris,

Fathering the panel with the sizer didn't help though.

A complete example that should work but doesn't (rather, the text
is displayed left aligned) is

To the issue of nested widgets: Up to now, I thought it to be comon
practice to fill your frame with one main panel and further father
that with alle the widgets necessary, grouping it together with
sizers.

Thanks in advance,

Hey again,

after searching through the list again, I've found the problem to be a
known bug for wx in a GTK environment (which is the case for me), see
http://groups.google.com/group/wxpython-users/browse_thread/thread/d1700040920eeef7

The solution so forth (at least the one that works for me out of the
box) is

···

####
from wx.lib.stattext import GenStaticText
####

and use that class instead of wx.StaticText

Thanks though and sorry for posting an already known problem,

uku

darn, but it looks from another post like you found a solution.

To the issue of nested widgets: Up to now, I thought it to be comon

that with alle the widgets necessary, grouping it together with
sizers.

yes, you generally don't want to put all your widgets directly on a Frame. What I suggest is that you subclass wx.Panel, put your widgets there, bind them there, then put that Panel on your Frame.

Why is it undesirable to have objects directly within a frame?

Because the Panel is where things like tab traversal is implemented, and also other things related to being a container of controls.
