| gtkTextViewScrollToIter {RGtk2.10} | R Documentation |
Scrolls text.view so that iter is on the screen in the position
indicated by xalign and yalign. An alignment of 0.0 indicates
left or top, 1.0 indicates right or bottom, 0.5 means center. If use.align
is FALSE, the text scrolls the minimal distance to get the mark onscreen,
possibly not scrolling at all. The effective screen for purposes
of this function is reduced by a margin of size within.margin.
NOTE: This function uses the currently-computed height of the
lines in the text buffer. Note that line heights are computed
in an idle handler; so this function may not have the desired effect
if it's called before the height computations. To avoid oddness,
consider using gtkTextViewScrollToMark which saves a point
to be scrolled to after line validation.
