| Allegro CL version 8.2 Minimally revised from 8.1. 8.1 version |
Arguments: window position &key delay-redraw
Scrolls window to position and updates the position of the slider in the scrollbar. Returns the new scroll position. Redrawing is delayed if the keyword argument delay-redraw argument is true. position must be a position (see make-position).
An application may override the default method of this and several
other generic functions in order to implement a custom scrolling
scheme that scrolls by logical picture objects rather than by
pixels. See the source code of the example entitled
'Scrolling by arbitrary objects rather than pixels'
on the Examples tab of the
Navigator
dialog
for a complete
example. More on this point and a list of the relevant generic
functions can be found on the horizontal-scroll-bar
and vertical-scroll-bar
pages.
See also scroll-window-to-middle which scrolls a window so equal amounts are scrolled off the left and right and the top and bottom.
