Re: scrolling and GtkTextView

[Razvan <razvaneduard xnet ro>]

found a solution to the scrooling problem: use marks:

gtk_text_view_scroll_to_mark(GTK_TEXT_VIEW(ircSp->textView),mark,0.0,FALSE,1,1);

Probably because in docs at gtk_text_view_scroll_to_iter() is write:

"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 
gtk_text_view_scroll_to_mark() which saves a point to be scrolled to 
after line validation."
