scroll_to_iter

Description:

public bool scroll_to_iter (TextIter iter, double within_margin, bool use_align, double xalign, double yalign)

Scrolls this 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 [ method@Gtk.TextView.scroll_to_mark] which saves a point to be scrolled to after line validation.

Parameters:

this	a `GtkTextView`
iter	a `GtkTextIter`
within_margin	margin as a [0.0,0.5) fraction of screen size
use_align	whether to use alignment arguments (if false, just get the mark onscreen)
xalign	horizontal alignment of mark within visible area
yalign	vertical alignment of mark within visible area

Returns:

true if scrolling occurred
