Thanks!
But in GTK+2 we could change background in layout with this:
// Set picture as background.
// gdk_pixbuf_render_pixmap_and_mask (pixbuf, &background, NULL, 0);
// style = gtk_style_new ();
// style->bg_pixmap[0] = background;
// homeWindow = GTK_WIDGET(gtk_builder_get_object(builder,
"layout_Home"));
// gtk_widget_set_style (GTK_WIDGET(homeWindow), GTK_STYLE(style));
How i know witch containers draw background?
THanks
