I assume you are trying to model the wxLua functions on this version of
Read():
bool Read(const wxString& key, wxString* str, const wxString& defaultVal)
Would it not make more sense to base it on this version:
wxString Read(const wxString& key, const wxString& defaultVal)
The wxPerl and wxPython implementations are all based on this second
version.
Currently the wxLua implementation looks like the second version but
acts like the first. This is pretty confusing for a wxLua newbie. Just
working with the Lua documentation I would never have figured out what
was going on. I only found out by looking at override.hpp. As wxLua
does not have detailed function-by-function documentation is it not best
to try to keep the functions looking as much like their C++ counterparts
as possible? By the way, that wasn't a dig at wxLua's documentation!
To be honest, how often do you need to know if you are using the default
or not? I know I have never needed to. In the very rare event that you
do actually need to check if the value was in the config you can always
have a default that should never appear in the config.

I have to admit I didn't think of that. Thanks for the tip.

Yup, been caught by that one a few times :-)

Yes, I thought of that a few seconds after sending the mail. Do you know
a good way of going the other way?
this obviously won't work:
cfg:Write("Foo",myCheckBox:GetValue())
At the moment I have a small function that takes a bool and returns an
int but there must be a better way.
Thanks for your help,
Les
