WxTextCtrl and Sizer problem

[Seb S]

Hello,

I am trying to make a simple window with one panel containing a textctrl. I
had this working with absolute size for the panel/textctrl but now I am
trying to make it work with a box sizer.

The problem is the textctrl is now too short and I can't see the text when
my program starts. If I specify the size for the text control eg
size=(300,50) the text control will get a bit longer but not long enough (it
will only go to certain length no matter what I put in size).

It is probably a really obvious error but I can't seem to find it. I've
included the section with the bug in bug.py and the rest of my code in
case it's needed in gui_test.py. Also I'm pretty new at programming so any
comments on style/anything helpful are welcome :)

Thanks in advance for any help.

You are putting the textctrl on the panel, but adding it to a sizer that
is assigned to the frame. Instead assign this sizer to the panel, and
if you want you can create another sizer with the panel in it and assign
that sizer to the frame.

BTW, please reread http://wiki.wxpython.org/MakingSampleApps Your
sample was not minimal and not runnable.
