RE: displaying a number on screen

[Shawn Bakhtiar <shashaness hotmail com>]

Try retreiving the cairo context for the widget you want to draw in and try this:


    /* Create the default Layout */
    layout = pango_cairo_create_layout(cr);

    /* Atach the font descriptor */
    font_description = pango_font_description_new();

    /* Setup Fonts and color and other layout attributes*/
    pango_font_description_set_family(font_description,"Helvetica");
    cairo_set_source_rgba(cr, 0.3, 0.3, 0.3, 1.0); 
    pango_font_description_set_absolute_size(font_description, 0.28 * PANGO_SCALE);
    pango_font_description_set_weight(font_description,PANGO_WEIGHT_BOLD);


    pango_layout_set_font_description(layout,font_description);

   gchar * l1 = g_strdup_printf("%s-%d",label->aid,label->nid);

    cairo_move_to(cr, 0.05 * xmultip, 0.00 * ymultip);

    pango_layout_set_text(layout,l1,-1);

    pango_cairo_show_layout(cr,layout);


You can also use 

    pango_layout_set_markup(layout,l1,-1);


using Pango markup to change text style.
