A text position is an unsigned int (which for reasons of compatibility is
- still a long) from 0 to GetLastPosition() inclusive. The positions
+ still a long as wxTextPos) from 0 to GetLastPosition() inclusive. The positions
correspond to the gaps between the letters so the position 0 is just
before the first character and the last position is the one beyond the last
character. For an empty text control GetLastPosition() returns 0.
