Solved not undoable replace_all with adding two lines:
source_buffer.begin_user_action();
and
source_buffer.end_user_action();
..................
private void replace_all()
{
string search_string = replace_search_entry.text;
string replace_string = replace_entry.text;
Gtk.TextSearchFlags flags = Gtk.TextSearchFlags.TEXT_ONLY;
Gtk.TextIter start_iter, match_start, match_end;
source_buffer.get_start_iter (out start_iter);
while (start_iter.forward_search (search_string, flags, out
match_start, out match_end, null))
{
source_buffer.begin_user_action();
source_buffer.@delete (ref match_start, ref match_end);
source_buffer.insert (ref match_start, replace_string,
replace_string.length);
start_iter = match_start;
source_view.scroll_to_iter (start_iter, 0.10, false, 0, 0);
source_buffer.end_user_action();
}
}
