Hello people.
I've made a small text editor, in which I want to insert markup. I used
the GtkSourceView widget.
If there is a selection, I want to insert tags around the selection,
and I'd like to remain the selection as it was. As I understand, this
means I have to define right_gravity to the left tag, and left_gravity
to the right one.
This doesn't seem to make any difference... Left works, right tag
always lands inside the selection. To be sure of the order of the tags,
I even call gtk_text_iter_order.
Can someone indicate my problem?

GtkTextIter start, end;
GtkTextMark *start_mark, *end_mark;
gboolean empty;
char *p;
empty = !gtk_text_buffer_get_selection_bounds(GTK_TEXT_BUFFER(src_bff),
&start, &end);
if (empty) {
p = g_strdup_printf("%s%s", str1, str2);
gtk_text_buffer_insert(GTK_TEXT_BUFFER(src_bff), &start, p, -1);
g_free(p);
} else {
gtk_text_iter_order(&start, &end);
start_mark = gtk_text_buffer_create_mark(GTK_TEXT_BUFFER(src_bff), NULL,
&start, FALSE);
end_mark = gtk_text_buffer_create_mark(GTK_TEXT_BUFFER(src_bff), NULL,
&end, TRUE);
gtk_text_buffer_get_iter_at_mark(GTK_TEXT_BUFFER(src_bff), &start,
start_mark);
gtk_text_buffer_insert(GTK_TEXT_BUFFER(src_bff), &start, str1, -1);
gtk_text_buffer_get_iter_at_mark(GTK_TEXT_BUFFER(src_bff), &end, end_mark);
gtk_text_buffer_insert(GTK_TEXT_BUFFER(src_bff), &end, str2, -1); }
}
