Ok. I admit that!
>From what I can see Traits can make coding GUI much MORE clearer than wxpython and faster.
But being in the middle of finishing a first release of the workbench - having spent so many hours of coding the GUI wxpython... aaarff - changing now does NOT make me feel comfortable... . Also I want to use the soft on Win and Linux.
And I am not sure that Traits could handle what I need.
I will release soon a first version and you will give you opinion if it could be dealt with by Traits.
For example: creating one datapage of the workbench can certainly be made with Traits (a datapage being a notebook which include different pages of different type such datagrid, graph, shell, etc..).
But then I use a notebook inside a notebook to generate the dataset... -ie set of datapages. So I am not so sure that it would easy to handle with Traits and control all the controls...). I will let you judge when it will be released.
PS for Gael: je n'ai tjs pas compris a quoi sert SciLab... Il ya 6 mois j'ai considere scilab pour mon developpement. Puis quand j'ai vu le bastringue j'ai laisse tombe. C'est vraiment afreux... Pourquoi 'ils' n'ont pas utilises Python et/ou developpes une GUI pour octave ... parfois je m'interroge sur les choix 'politico-businesso-scientifique' francais...on sait vraiment depenser les sous en France.

Concerning TraitsUI, I think it is a _great_ productivity gain. It is a
bit hard to learn for people who have never used a graphical toolkit, but
if you are fluent with wxPython, it should be pretty fast to learn.
Bear in mind that it is only a layer above wxPython, so if you understand
wxPython and if you read section 4 of my tutorial you can blend to two
As far as ETS goes it is a fantastic toolsuit but is not terribly well
distributed currently (no packages under linux or mac) but the
developpers are very helpful and they are actively working on that.
I have never regretted using TraitsUI. The fact that the widget
manipulation code vanishes from my code make it much more readable, and
automatic generation of panels is great. The biggest problem with it is
that it is still young.
If you have feedback on my tutorial, I would be very interested, I am
trying to lower the effort to learn GUI programming as much as possible.
I see many people around me who need this.
