[maemo-developers] How can I change the background color of a GtkButton when it is activated

[From: Yao Wang]

Hello everyone.
        I am developing a GUI application on maemo, in which GtkButton is
used.

        The default color when I pressed down the button is blue. I want to
change the background color of button when it is pressed and recover its
origin background color when it is released.

        I tried to implemented it using the following code:

              GdkColor color;
    gdk_color_parse ("red", &color);
    gtk_widget_modify_bg(GTK_WIDGET(button), GTK_STATE_ACTIVE, &color);

        However, it dose not work at all.
        Could anyone kindly give me some advices or suggestions ?
        Thanks in advance.
