How to detect if GtkScrolledWindow is scrolled to bottom?

I would like to know if there is a way to know if the user scrolled GtkScrolledWindow (containing a GtkTextView) to the bottom or not.

Indeed, I automatically scrolled to the end with:

gtk_text_buffer_get_end_iter(tbuf, &iter);
GtkTextMark *insert_mark = gtk_text_buffer_get_insert(tbuf);
gtk_text_buffer_place_cursor(tbuf, &iter);
gtk_text_view_scroll_to_mark(text, insert_mark, 0.0, TRUE, 0.0, 1.0);

But I don't want to run this code if user has scrolled by himself.

Solution

  • I think I have the answer to my own question:

    This code should detects if the edge is reached.

    value = gtk_adjustment_get_value(adjustment);
lower = gtk_adjustment_get_lower(adjustment);
upper = gtk_adjustment_get_upper(adjustment);
page_size = gtk_adjustment_get_page_size(adjustment);

if (value == upper - page_size)
    edge_reached = TRUE;
