font delete

font delete fontname ?fontname ...?

Delete the specified named fonts. If there are widgets using the named font, the named font won't actually be deleted until all the instances are released. Those widgets will continue to display using the last known values for the named font. If a deleted named font is subsequently recreated with another call to font create, the widgets will use the new named font and redisplay themselves using the new attributes of that font.
