2001-04-12 Anders Carlsson <andersca@codefactory.se> * gtk/gtkcellrenderertextpixbuf.c (gtk_cell_renderer_text_pixbuf_class_init): It's pixbuf_pos, not pixbufpos. * gtk/gtkcellrendererpixbuf.c (gtk_cell_renderer_pixbuf_render): Fix small typo. * gtk/gtkcellrenderer.c (gtk_cell_renderer_get_property): xpad and ypad are unsigned insts, therefore use g_value_set_uint. (gtk_cell_renderer_set_property): Likewise, use g_value_get_uint.
