scroll_bar-amount: intThese slots represent the scroll-request. See also scroll_bar->event
and
scroll_bar<-message.
The values are:
- -
unit - Scroll to a position in the file (document), per page or line. The
interpretation of these units is left to the scrolled object.
- -
direction - Scroll forwards (towards the bottom/right) or backwards (towards the
top/left) of the document. If the unit is
file, -direction is goto.
- -
amount - For -unit is
file or page, this is a
promilage. Thus, {file, goto, 300} goes to 30% of the file,
{page, forwards, 500} goes half a page down. For -unit is line, this is
a line-count.
