PangoLayout

[Chris Hoefler <hoeflerb brandeis edu>]

Ok, Pango is driving me crazy. I am trying to set attributes on a
PangoLayout, but I can't seem to get it to work. Here is the code:

PangoLayout *layout;
PangoRectangle logical_rect;
PangoAttrList *layout_attr;
PangoAttribute *text_size, *text_weight;
gchar label_str[100];

<snip>

layout = gtk_widget_create_pango_layout (widget, NULL);
text_size = pango_attr_size_new (100);
text_weight = pango_attr_weight_new (PANGO_WEIGHT_BOLD);
layout_attr = pango_attr_list_new ();
pango_attr_list_insert (layout_attr, text_size);
pango_attr_list_insert (layout_attr, text_weight);
pango_layout_set_attributes(layout, layout_attr);

<snip>

g_snprintf (label_str, sizeof (label_str), "%.*f", AXIS_PRECISION,
        major_tick_num);
pango_layout_set_text (layout, label_str, -1);
pango_layout_get_extents (layout, NULL, &logical_rect);
gtk_paint_layout (widget->style, widget->window, GTK_STATE_NORMAL,
        FALSE, NULL, widget, "tick_label",
        major_tick_x_pos - PANGO_PIXELS (logical_rect.width / 2),
        ysrc + axis_height, layout);

I am trying to draw some text onto a new widget I am creating. When I
run this code, the correct number is drawn, but without the attributes
(bold, small font). If I move the pango_layout_set_attributes after the
pango_layout_set_text, that has no effect. Neither does applying a
property like pango_layout_set_indent. Is there some layout refresh
command I am missing here?
