problem with gtk_widget_style_get

[Abirami T <tabirami tataelxsi co in>]

hi,
        I'm trying to access the treeview properties set through rc file as below,

      gboolean num = 0;
        GdkColor color;
        gtk_widget_style_get(treeview_widget,
                                        "even-row-color",&color,
                                        "allow-rules",&num,NULL);

        The "allow-rules" value is properly retrieved in num variable, but
"even-row-color"
  value is not properly retrieved in color variable.

        How to retrieve the GdkColor value properly?

Abirami.
