Subject: How to calculate X when dealing with truncate-lines non-nil.
Date: Wed, 27 Sep 2017 20:16:11 -0700 [thread overview]
Message-ID: <m2fub7pl6s.wl%esq@lawlist.com> (raw)
In developing my own feature requests to draw crosshairs (#17684) using multiple fake cursors (#22873), I have reached a roadblock in understanding why
move_it_to (&it, PT, it.last_visible_x, it.last_visible_y - 1, -1, MOVE_TO_POS | MOVE_TO_X | MOVE_TO_Y);
is giving me an it.current_x of non-existent coordinates to the imaginary right of the visible window when truncate-lines is non-nil.
For example, my screen is 1920 x 1080. When PT is somewhere to the right of the initial visible window, I'm getting X coordinates to a tune of 8,000 and so forth.
How can I obtain the correct X, Y, HPOS, VPOS when dealing with a non-nil truncate-lines situation?
[Everything works as expected when truncate-lines is nil.]
Thanks,
Keith
