    pixmap_path "/usr/include/X11R6/pixmaps:/home/imain/pixmaps"

    # Here is a list of all the possible states.  Note that some do not apply to
    # certain widgets.
    #
    # NORMAL - The normal state of a widget, without the mouse over top of
    # it, and not being pressed, etc.
    #
    # PRELIGHT - When the mouse is over top of the widget, colors defined
    # using this state will be in effect.
    #
    # ACTIVE - When the widget is pressed or clicked it will be active, and
    # the attributes assigned by this tag will be in effect.
    #
    # INSENSITIVE - When a widget is set insensitive, and cannot be
    # activated, it will take these attributes.
    #
    # SELECTED - When an object is selected, it takes these attributes.
    #
    # Given these states, we can set the attributes of the widgets in each of
    # these states using the following directives.
    #
    # fg - Sets the foreground color of a widget.
    # fg - Sets the background color of a widget.
    # bg_pixmap - Sets the background of a widget to a tiled pixmap.
    # font - Sets the font to be used with the given widget.
    #

    # This sets a style called "button".  The name is not really important, as
    # it is assigned to the actual widgets at the bottom of the file.
