* base - Sets the background color for widgets that have editable text.
* bg_pixmap - Sets the background of a widget to a tiled pixmap.
* font_name - Sets the font to be used with the given widget.
* xthickness - Sets the left and right border width. This is not what you might think; it sets the borders of children(?)
* ythickness - similar to above but for the top and bottom.
*
* There are several states a widget can be in, and you can set different colors, pixmaps and fonts for each state. These states are:
* NORMAL - The normal state of a widget. Ie the mouse is not over it, and it is 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 - This is the state when a widget is 'greyed out'. It is not active, and cannot be clicked on.
* SELECTED - When an object is selected, it takes these attributes.
