The path list is a convenient way of storing a number of directories, and when presented with a filename without a directory, searching for an existing file in those directories. Storing the filename only in an application's files and using a locally-defined list of directories makes the application and its files more portable.
Use the FileNameFromPath global function to extract the filename from the path.

void wxPathList(void)
Constructor.
void AddEnvList(char *env_variable)
Finds the value of the given environment variable, and adds all paths to the path list. Useful for finding files in the PATH variable, for example.
void Add(char *path)
Adds the given directory to the path list, but does not check if the path was already on the list (use wxPathList::Member) for this).
void EnsureFileAccessible(char *filename)
Given a full filename (with path), ensures that files in the same path can be accessed using the pathlist. It does this by stripping the filename and adding the path to the list if not already there.
char * FindValidPath(char *file)
Searches for a full path for an existing file by appending file to successive members of the path list. If the file exists, a temporary pointer to the full path is returned.
Bool Member(char *file)
TRUE if the path is in the path list (ignoring case).
