Sizers, finally

I've got the GUI laid out in my next wx app (pure wx, no Pythoncard),
and it's shaped up pretty well, with much less problems than the
previous program I attempted using sizers.

This GUI uses several sizers (all BoxSizers, unfortunately) and I'm
finally getting more comfortable using them, even after not having
written any GUI code for a few months. (That doesn't mean I wont trip
over them the next time I use sizer. I probably will, but now have
something I've written to look back on)

I want to thank the readers/contributors to this list for helping me
through my problems.

For the newbies: Here are some things you should seriously take
advantage of if you're just starting with wxPython or having problems
in general

     1. The wx Wiki ---> http://wiki.wxpython.org/FrontPage
     2. The book: "wxPython in Action"   -----> www.manning.com/rappin/
         (there's even a download version you can read on the bus/train to work)

     3. Mike's Sizer tutorials ------->  http://wiki.wxpython.org/SizerTutorials

Robin has/had a very useful suggestion regarding sizers: draw a crude
diagram of what you expect the layout of your sizers to look like, as
if the sizers were visible. He had emailed me a jpg which showed the
layout of the sizers in a program I had problems with, and it really
does make you think differently about how the layout should be, and
how to get your layout to be that way. If I still had the jpg, I would
attach it. It's not in my emails, and I think it was on my laptop

Do the sizers have an attribute that can be enabled, which shows their
border/boundary lines?
(like the Grid lines in Word and Excel tables).

One way to achieve this is to use the inspection tool.

See, eg, the  module inspection_tool_and_sizers.py in LearnSizers8.zip available
at http://spinecho.ze.cx/

Does gmane work for you ? I'm only able to read messages like
weft didn't produce an output.     or

Re: Sizers, finally

The problem is that the  module inspection_tool_and_sizers.py in LearnSizers8.zip  IS NOT available at http://spinecho.ze.cx/: there is a link there, but it takes to nothing. Could please J.M. Fault reset it?

That link works for me...in Firefox 3 on Windows XP. I didn't try it 
with my other browsers. Regardless, I upzipped it and included the file 
you were looking for.

Re: Sizers, finally

Thanks for your kindness, Mike, but the file I was looking for is just the full .zip (LearnSizers8.zip). And my Firefox must be wet, because this time the link took me to iFrance, "le portail des jeunes actifs". Et, hélas, je ne suis plus jeune, et pas trop actif non plus.
Would it be too much trouble for you, to send the whole file?

No problem. It should be attached to this email. Hopefully your web 
client accepts zip files. If not, I can tar it.

I was able to download LearnSizers8.zip an unzip it.

However, after the recent link to this was posted
http://wiki.wxpython.org/Widget%20Inspection%20Tool

I'm not able to get the boarders of the sizers to be displayed.
I've got the inspection too launched from my app, but this doesn't
seem to work for me

"Highlight: Highlight in the live window the item that is currently
selected in the widget tree. Top-level windows will be flickered, and
other items will have borders drawn around them for a few seconds, as
shown in the screenshot below."

Mine doesn't. It has all the same toolbar buttons that the wiki shows. 
I'm using the 2.8.8.0 version of the Demo. What about you?

Re: Sizers, finally

What does the version of the demo have to do with the sizer borders
being highlighted?
The inspection tool isn't part of the demo, it's part of the core wx package.

It probably doesn't. But I think Robin added that feature within the 
last two or three releases of wxPython. I should have said I was using 
wxPython 2.8.8.0. The wiki does show that Robin was running 2.8.8.0 in 
the screenshot and it was updated at the end of June. I trolled back 
into the archives and found Robin mentioning the following to me actually:

"Take a peek at the new preview build of 2.8.8.  I've made some 
enhancements to the widget inspection tool that lets you highlight 
sizers and widgets in the live app." I received this on June 5th, 2008 
on the list. So I think you'll just need to upgrade.

The sizer highlight (and others) was added in 2.8.8.0.
