1)Anomaly in space taken by rows in list boxes with different font sizes.
in GTK as the font size decreases, the row size seems not to proportionally
decrease, leading to loss of valuable screen real estate. This is best
illustrated in the accompanying png file (font_creep_wxPtyhonLists.png)
where I have set roughly the same font in a listbox on wxPython(on the
left) and on QT designer (on the right). As you will see one can fit more
items in the qt list box compared to the GTK one, and quite a lot of line
space is left blank above the text in GTK.
From your screenshots, it looks like you are using GtkCList and the
obsolete X font backend to GTK+. It's really pretty hard for us to
give an answer for those circumstances - my best guess is that
for some reason GTK+ is using a fontset where some of the fonts aren't
available in small bitmap sizes.
They are saying that it looks like old technology GTK, which if you are using wxPythonGTK it is. That version uses gtk+-1.2.x. If you use wxPythonGTK2 then it is gtk+-2.2.x and uses all new tech for rendering the fonts and such. wxGTK2 is still not as rock solid as wxGTK but it should be close.
2)The second ongoing problem is that it seems not possible, despite the
flags present, to have borderless controls (not 3D) controls. Whilst this
may seem petty having a 3d border round the text boxes and sometimes other
controls can interfere in some cases with design, and again means
ultimately (I know this seems petty) less room on the screen, when space is
at a premium
You are going to have to be more specific here. As far as we know,
it's quite possible to have a GTK+ theme with 1 pixel or even 0
pixel borders, and for the theme to draw the borders however it likes.
As I said, it is normally up to the theme how the widget decorations are drawn.
And there is a specific call to make GtkEntry borderless without
any resort to the theming system.
GtkEntry is the wdiget that is used in wxGTK2 for single line wxTextCtrl. (A different "old tech" widget is used in wxGTK.) A quick look at the source shows that something is being done with the wxNO_BORDER flag in this case, but I havn't tried yet to see if it is the Right Thing.

I note the comments about gtk2. I downloaded the rpm I found (17July03) and it
has a dependency of libGlcore.so.1. Looking for this on rpmfind points to
nvidia stuff (and for for pldlinux and asplinux) so I'm not sure how to

Could anyone give me a pointer on how to install this on Mandrake 9.1 + Debian
(I have two separate boxes).

AFAIK, libGlcore is simply one of the OpenGL libraries and is delivered
with XFree86. nVidia provides their own that is optimized for their
hardware. You should already have one on your system (provided OpenGL
works on your system). If you can run the 3D (OpenGL) screensavers then
you should be good to go.

I find myself doing 'slocate -u' fairly often and using 'slocate filename' as it seems the most reliable
way to get an answer but even it misses files at times for reasons I fail
to understand!

Yes, see below.
2) I've tried installing it and don't know where to go:

Why didn't you install this via rpm as well? You'll be prone to getting

- I installed wxGTK2.5-2.5.0-0.cvs20030319.6mdk.i586.rpm

You probably need the *-devel rpms as well (gtk2-devel, wxGTK-devel,
etc).

You have to compile wxPython from source with the --with-gtk2 (IIRC)
flag to configure.

You have to compile wxPython from source with the --with-gtk2 (IIRC)
flag to configure.
The exact instructions are in the README that comes with the source. I
built from (then) current CVS. Some of the instructions seem a little
off, but perseverence will pay off.
Good luck,

The system I built the wxPythonGTK2 RPM on has the nvidia drivers installed and so RPM detected that dependency automatically. (Anybody know off the top of their head how to ignore an auto dependency when building the RPM?)
You may be able to install that RPM on the Mandrake system with --nodeps flag, otherwise you can get the .src.rpm and build your own binary RPM with "rpmbuild --rebuild wxPythonGTK2-*-src.rpm". Make sure you have the libgtk+2.0_0-devel installed to get the headers and such for gtk2. For Debian you'll have to get the wxPythonSrc tarball and build from scratch.

2) I've tried installing it and don't know where to go:
- I compiled gtk+-2.2.2.tar.gz and it seemed to install ok
This should already be on your Mandrake 9.1 system, you just need to install the extra libgtk+2-devel RPM (or something like that.)
- I installed wxGTK2.5-2.5.0-0.cvs20030319.6mdk.i586.rpm
This is not needed for building wxPythonGTK2 since the wxGTK sources are inlcuded. (And it would be the wrong version of wxGTK anyway since you are working with wxPython 2.4.1.2.)
- if I install wxPythonGTK2-py2.2-2.4.1.2-1.i586.rpm I get failed dependencies on libGlcore.so.1. The only source of this file I could find on rpmfind was for distributions other than mandrake, and I already have an nvidia card on my system with nvidia drivers installed.
Probably because the NVidia files were not installed via an RPM, so the libGLcore is not known by RPM to be installed. Try installing the wxPythonGTK2 rpm with the --nodeps flag.
- If I try and compile the source rpm I get a message where it cant find something called -1GLU
Do you have libMesaGLU1-devel and libMesaGLU1 packages installed? If so then there was a bug in wxWindows' configure that assumed that the GL and GLU libs are in the same place, but if you have the NVidia glx drivers installed then that is not true but I thought that had been fixed before the 2.4.1.2 version. If not then a simple workaround is to just make symlinks in /usr/lib to all the /usr/X11R6/lib/libGLU* files.
3) Assuming someone is able to help get me up and running with this, will the wxPython demo then automatically use the gtk2?
Yes.
