Stripping characters of a wxString

I am working on an application written in C++ that primarily uses wxWidgets for its objects. Now, suppose I have the following wxString variable:

wxString path = "C:\\Program Files\\Some\\Path\\To\\A\\Directory\\";

Are there any ways to remove the trailing slashes? While wxString provides a Trim() method, it only applies to whitespace characters. I could think of converting the string to another string type and perform the stripping there and switch back to the wxString type (it is essential that I use the wxString type) but if there is a less convoluted way of doing things, I'd prefer that.
