Hi,

Since wxString (in wxWidgets 3.0) is based on std::basic_string, can I use stl algorithms on wxString? For example, I'd like to use copy_backward() on a wxString.

It isn't. It does use std::basic_string internally (unless disabled) but
it doesn't inherit from it which is usually meant by "based on".

You should be able to as it provides the same interface as standard string
class. If anything is missing, let us know.

You should be able to do it in both 2.9.0 and 2.8.x as well.

Thanks for the quick response. I re-read the wxString info, and saw where I made my mistake.

I'm currently using a vector of wxChar for my data, but I can't seem to find any documentation on how wxChar handles Unicode characters, or even if it does Unicode. I've been looking through the 3.0 docs at http://docs.wxwidgets.org/trunk. I must be missing something.

I'm considerring moving to wxString simply because it simplifies some data management for me, even though the data I'm dealing with is not a string.

wxChar is just wchar_t. You may want to use wxUniChar which is 32 bit
everywhere unlike it.

wxString is strongly geared towards working with strings even though you
should be able to use it with any data so you should use std::string if you
really need an 8 bit data container.
