Ah, the fog rises :-)   Will tend to it RSN !

Will do my best.

No. The *plugin* file in wxpython/gui/ need not (and should
not) contain any of the *business GUI* widgets. It simply
provides a wxPlugin derived class which loads the widgets
from, say, wxpython/  Now, if someone else
decides do write UI unrelated with the notebook plugins they
simply load the needed business widgets from
wxpython/ into another wrapper class. Eg.
Richard-space would instantiate the same classes as
Horst-space does but in Richard-space the parent wxWindow
would be part of cClinicalWindowManager while in Horst-space
it would be a sizer that's eventually plugged into the
notebook as a new page. No need for code from
wxpython/gui/*.py to mess at all with the notebook. Am I
making myself understood ?

I see. OK, now *thats* an option. Let the user decide whether
they want a notebook OR the 2/3 col layout. I think I am
getting what you are after. This might be doable after all.

Because a whole bunch of plugins may not have to do with
clinical things at all, eg. managing the contacts data. Those
widgets wouldn't be integrated with cClinicalWindowManager.
But it might make sense to either say:

All clinical functionality must be within
gmClinicalWindowManager (then we can have notebook tabs, too).


Either notebook tabs OR gmClinicalWindowManager.

In it's current incarnation, yes, I agree.
