I get an exception when trying to load the iceland sample for

Just updated the cvs repository. Changes are to the classification
dialog. You should now be able to view the classifications and change
some parts of them: double-click on the sample visual and type
numbers/ranges for the value.

Subject: [Thuban-list] TODO List
Message-ID: <1046281065.29697.142.camel@reisen>

Current functionality:
======================

The user can add/view classification groups and modify the visual
properties (stroke color, width, fill color) for single values and
ranges as well as change the values and ranges. There is no way to
generate these properties automatically. This information can be saved
and loaded from a file.


The following things concerning classification are needed before the
next release of Thuban:
====================================================================

Dialog Clean Up
---------------
The classification dialog doesn't look very nice. It was put together to
test some of the classes and some things are a bit rough.

Generating Ranges
-----------------
The user can add classification groups one at a time, but we need to be
able to automatically generate groups based on the kind of data that a
table field represents. If it is a series of floats then groups of
ranges are appropriate, but with strings singleton values are needed.

Generating the visual properties over many groups needs to be discussed.
I was thinking there could be predefined types such as False-Color which
could range from red to green, or the user could select a start and end
color. 

The code would also have to analyse the field values to determine how
many different values exist. In the case of strings this means building
a list of unique entries. In the case of floats it could mean
determining min and max values and then subdividing that range into
equal (perhaps) parts. The user should be allowed to specify this.

All this functionality will exist only in the classification dialog.
Once the classification groups are built Thuban uses the classification
class to render the map as normal.

If things go to plan (ha!) I should be spending most of next week
working on this part of things.

Tests
-----
Many of the classes have changed recently due to design modifications
and the tests don't reflect these changes. In some cases the tests don't
even exist.

General Code Inspection
-----------------------
I need to review some parts of the code and clean them up a bit. A few
places here and there could be written better (no specifics, just
general house keeping).

Subject: [Thuban-list] Python 2.2 and wxWindows 2.4
Message-ID: <20030226190554.GA25985@intevation.de>

Hi,

this week we (Bernhard Herzog, Bernhard Reiter, Jonathan Coles, Frank
Koormann and myself) had a discussion on the further development
we want to perform until June.

One important decision, however, is which version of Python and
wxWindows Thuban should be compatible for mid-term future (say
about 2-3 years).
We came to the conclusion that this should be Python 2.2
and wxWindows(wxPython) 2.4.
Though both are not yet the standard on many GNU/Linux distribution,
we expect them to be within about a year.

The forthcoming release 0.2.0 will already depend on this (at least
it is only tested against Python 2.2 and wxWindows 2.4 from now on).

All the best

	Jan

Hi,

I just added jonathan as a manipulator for the
Thuban request tracker. So, now you can asign bugs
directly to him ;-)

Also, I configured the thuban bug tracker to be a bit more verbose.

Some items that just came to my mind:
- replace term 'visual' by 'symbol'.
- add a 'Remove' button to get rid one or many marked classes
- Make the frame a dialog window.
- add hot-keys to the buttons
- make the widgets resize with the window size

I propose to skip the range generation for release 0.2.0.
You can make the button ivisible for the release and afterwards
start implementation of this quite sophisticated feature.

yeah, those need to be fixed and some missing to be added for 0.2.0.

good idea for 0.2.0.


Finally, we should remove the critical bugs listed in the thuban
bug tracker - of course :-)
