[Boa Constr] boa app runtime config problem

[Hans-Peter J. <hp...@ur...>]

Hi Riaan et al.,

following the docs on "Special frame attributs", I try to
control my layouts this way (on the main frame):

[...]
import config
[...]

class MainUI(wxFrame):
    _custom_classes = {'wxScrolledWindow': ['FaxView', 'wxScrolledWindow'],
                                           'wxPanel': ['FaxList', 'wxPanel']}
    [...]

    def _init_ctrls(self, prnt):
	[...]
        self.mainSplitter.SplitHorizontally(self.listSplitter, 
		self.viewSplitter, self.MainSplit)
	[...]

    def __init__(self, parent):
        self.initdone = false
        self.minPaneSize = 0	# fine
        self.SashSize = 5	# fine
	self.MainSplit = 180	# design time value
        self.cfg = config.Config()
        self.cfg.load()
	self.MainSplit = self.cfg.MainSplit # run time value
        self._init_ctrls(parent)
	[...]

but this results in KeyError: MainSplit during Designer launch:
00:53:13:  config.Config()

No matter how I instanciate my config class, I get this key error. 
Any ideas?

Also, I would like to pass my config instance to my subclasses in the
constructor. The docs say, this is a nono, because it's neither a 
simple nor a wxPython type. 

I workaround this with a Config method in the subclass, but again:
Parameter, which modify appearance have to be handled manually and
disturb screen appearance on start up (gets drawn with design time
values, but modified quickly thereafter)

Any help on this topic is greatly appreciated.

Cheers,
