I don't mean "between" anything. My mental model of the mapping of a coordinate component to a screen pixel (in X) is direct. It doesn't admit subpixel (fractional) specification. Left-most pixel is numbered 0, and "at 0" refers to that pixel. So in my description "at" is actually superfluous. Thanks for prompting this realization! Please (re-)read as "pixel 30,y". More importantly, if you remove the "- 1" part, per my suggested patch, do you see a change in the cursor dimensions when you toggle a window between selected (filled block cursor) and non-selected (hollow block cursor) status? I confess i haven't yet run the test case, but just jumped into the discussion pedantically. > I think it hinges on what how "the specified rectangle" > is specified. This sentence didn't parse. How the rectangle is specified is described on the same page, so you've probably read that already. Likewise, i have not visited that page. All i know is that there are different models for describing a rectangle (even w/in the same system -- e.g., SDL "rectangle" and SDL_gfx "draw rectangle") and that surfing among them one finds many OBOEs sounding right and left... :-D =2D-=20 Thien-Thi Nguyen GPG key: 4C807502 (if you're human and you know it) read my lisp: (responsep (questions 'technical) (not (via 'mailing-list))) =3D> nil --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAlRArDsACgkQZwMiJEyAdQKgBACfUvwXbLd6GAFa2cr2Y0VLi8YX mn4AnRFQYcyfB81gUH7cndzAHZjLwLSA =XmSH -----END PGP SIGNATURE----- --=-=-=--
