Method
GtkTextViewscroll_to_iter
Declaration [src]
gboolean
gtk_text_view_scroll_to_iter (
GtkTextView* text_view,
GtkTextIter* iter,
double within_margin,
gboolean use_align,
double xalign,
double yalign
)
Description [src]
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 that this function uses the currently-computed height of the
lines in the text buffer. 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 gtk_text_view_scroll_to_mark() which saves a point to be
scrolled to after line validation.
