Hi,

How to make gtk_rc_get_style_by_paths() return not NULL?
How to change my example below?

Thanks,
    Vitaly.

Example:
#include <gtk/gtk.h>

int
main (int argc, char** argv)
{
    GtkWidget* widget;
    GtkWidget* window;
    GtkStyle* style;

    gchar* path = NULL;
    gchar* class_path = NULL;


    gtk_init (&argc, &argv);

    widget = gtk_arrow_new (GTK_ARROW_UP, GTK_SHADOW_IN);
    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
    gtk_container_add (GTK_CONTAINER (window), widget);

    if (TRUE)
    {
        gtk_widget_path (widget, NULL, &path, NULL);
        gtk_widget_class_path (widget, NULL, &class_path, NULL);
    }

    style = gtk_rc_get_style_by_paths (gtk_widget_get_settings (widget),
                                       path, class_path,  G_OBJECT_TYPE
(widget));

    if (!style)
    {
        printf ("\nstyle is %p, widget style = %p\n", style,
                gtk_rc_get_style (widget));
        printf ("path = '%s', class_path = '%s'\n", path, class_path);
    }

    if (widget)
        gtk_widget_destroy (widget);
}


Output:
style is (nil), widget style = 0x8068d80
path = 'GtkWindow.GtkArrow', class_path = 'GtkWindow.GtkArrow'
