AFAIK, the pango context used by the GtkCellRenderer is the same used
by the treeview, so try to make something like:
context = gtk_widget_get_pango_context (my_treeview)
About how to get what you want, I think that the next pseudocode could
be your base:
gint
compute_break_position_on_my_text (my_tree_view, text)
{
width = gtk_tree_view_column_get_width(the_column_of_my_treeview)
context = gtk_widget_get_pango_context(my_tree_view);
layout = pango_layout_new(context);
pango_layout_set_markup(layout, text, -1);
pango_layout_xy_to_index(layout, width * PANGO_SCALE,
0, &offs, &trailing);
g_object_unref(layout);
brk = g_utf8_offset_to_pointer(text + offs, trailing);
return brk - text;
}
But I'm not sure, as I'm not a pango expert. Hope this helps.
