#With this code we connect the status icon using "activate" which is only LEFT click.
# As a result, the on_click function is called only with LEFT click.
# No actions assigned in Right Click of gtkstatusicon.

        Bellow are the python prompts in mismatched data given
        var1: parent_menu_shell - GtkWidget or None
        var2: parent_menu_item - GtkWidget or None
        var3: func - must be a callable object or None
        var4: an integer is required - works with any integer. Acc to pygtk this is "button"
        var5: last argument must be int or long - applied random ints but not work. pygtk=>time
