[GRASSGUI] Re: [GRASS-user] wxgrass: porblem with combo

[Michael Barton]

Jarek,

Thanks Michel
I tested it more, and I confirm: having 2.6 cousing problmes with
wx.combo, but this not allow install aplications depending on wxPython2.6
The only solution is to install 2.6 on very fresh system, next 2.8 next
other aplication. But At least two aplications on Ubuntu installed from
repos (for examle wxGlade and pgAdmin3 if installed after) made wx2.6
default
I don't know if idea of depending wxGRASS on at least 2.8.1 is good idea
(I red this in last Jachym article on his page). Generally most ubuntu
application are dependend on wx2.6.

As Hamish says, 2.8 is largely a bug fix for 2.6. However, there are a few
new controls (or slightly modified versions of existing ones).

The reason for depending on 2.8.x is that once we go to serious production
testing and use, the version of wxPython may well get defacto frozen because
of the need to maintain backward compatibility for GRASS within a version
number. So we're developing in the most current version so that we don't
start out a couple versions behind when we go to widespread use.

I don't know if following example is
Probably every grass user know pgadmin3 (postgreSQL manager) for now in
ubuntu repositories is version 1.4.3 depending on wx2.6. I asked
developers why not 1.6.1 wchich is more advanced. It is because, 1.6.1
is dependend on wx2.8, ad as long as they will not be sure if wx2.8 is
fully compatibile with other aplications they will not add 1.6.1

AFAICT, 2.8 is fully backward compatible with 2.6. I ran into the version
problem with wxGlade, but found out that it is necessary to change only a
line or two to run with 2.8. Even easier, you can simply download the
wxGlade source code and use it. Because it's all in wxPython, there is
nothing to compile. Just build it and run from "source".

I don't know about pgadmin3. I thought that was in PHP rather than wxPython.
If in wxPython, however, you probably only need to find the place where it
check (and requires) 2.6 and change it to 2.8. Since wxPython files are all
text files, this should be pretty easy.

Hope this is helpful

Michael

Thanks for message
I use wxglade 0.5 "from source" it run fine without any modification. I
give it only as a example ....
pgadmin3 is not php (this is phppgadmin) it is binary application just
dependend on wx2.6 newest pgadmin3 is dependend on wx2.8 nad there are
huge problem with its compilation on ubuntu just due to wx2.8 (this is
information from pgadmin3, developers I don't ask anybody here how to
solve this :)) )

see my next to message on wx2.6 and 2.8 conflict in dependences on
ubuntu (and probably other linux distros) For now there is no package
dependend on wx2.8 - I only point that depending grass on wx2.8 may
conflict with other ubuntu (and other distro) dependencies in next to 12
month - it probably won't be a problem if realase is plannded later
