Applying style changes to a widget

["Craig Harding" <craigwharding gmail com>]

Hi, I'm running the following code to decrease the vertical space
between nodes in a GtkTreeView.

GString *style = g_string_new("");
g_string_append(style, "style \"blist-vspace-style\" {\n");
g_string_append(style, "GtkTreeView::vertical-separator=0\n");
g_string_append(style, "\n} widget \"*pidgin_blist_treeview\" style
\"blist-vspace-style\"");

which creates a gtkrc-type style for my widget. I am then running the
following code to immediately set the style (above) to the widget.

gtk_rc_parse_string(style->str);
GtkSettings *setting = NULL;
setting = gtk_settings_get_default();
gtk_rc_reset_styles(setting);

My question is.. Is there another way to apply the style changes
online (immedaitely) to a widget without using the GtkSettings method
above?

Thanks,

Craig.
