Expand description

Get string from wxCommandEvent. Returns the length of the string (excluding null terminator), if any error, -1 returned. If buffer is non-null and buffer_len > 0, copies up to buffer_len - 1 characters and null-terminates. If buffer is null or buffer_len == 0, does not copy anything.
