Hi all,
I'm creating a subclass of wx.lib.sized_controls.SizedDialog containing
some TextCtrls and a standard button sizer, but for some reason, any
control that has the wx.TE_READONLY style flag set doesn't appear to be
a part of the tab order inside the dialog. I can set focus to such a
control by clicking on it or using its associated mnemonic, but as soon
as I tab away from it, I can't tab back.
I've attached a sample, dialog_sample.py, which demonstrates the
problem. First, notice that you can tab to the editable field, type
some text, and it then appears in the second, which is set to be
read-only. You can press Alt+N to jump keyboard focus to the read-only
control, but otherwise, you cannot set focus to it using the keyboard.
OS: Windows 7 Professional, 64-bit
Python 2.7.10 (default, May 23 2015, 09:40:32) [MSC v.1500 32 bit
(Intel)] on win32
wxPython 3.0.3.dev1830+0b5f910
Apologies if the size of the sample dialog doesn't permit you to see it
clearly - I'm visually impaired so just used the default, initial size.
Many thanks.

Hi James,
I confirm this (some time ago I posted the same question, btw). I
would like to get an answer, but if you need to handle this really
fast, here is a work-around:
set your field as TE_MULTILINE even if you don't need to be so. Then
it gets focusable. Don't know why, but it is so.
P.S. The world is small

This is by design, and it's a Windows thing, not a wx thing. A
read-only control cannot receive any input, so there is no need to
include it in the tab order.

Understandable (I suppose) but wx.TextCtrls with the wx.TE_MULTILINE
flag set don't exhibit this behaviour. The world of keyboard
accessibility sure is full of inconsistencies...

Ah, well, it might be used to show text - based on values in
other fields - to be used for copy/paste. So it depends.

That's exactly what I'm using it for, so I don't really buy that this
isn't a bug. I'll report it at some stage unless it's Windows API
behaviour.
