46             =head1 DESCRIPTION
47              
48             This container widget draws a frame around a single child widget.
49              
50             =head1 STYLE
51              
52             The default style pen is used as the widget pen. The following style pen
53             prefixes are also used:
54              
55             =over 4
56              
57             =item frame => PEN
58              
59             The pen used to render the frame lines
60              
61             =back
62              
63             The following style keys are used:
64              
65             =over 4
66              
67             =item linetype => STRING
68              
69             Controls the type of line characters used to draw the frame. Must be one of
70             the following names:
71              
72             ascii single double thick solid_inside solid_outside
73              
74             The C linetype is default, and uses only the C<-|+> ASCII characters.
75             Other linetypes use Unicode box-drawing characters. These may not be supported
76             by all terminals or fonts.
77              
78             =item linetype_top => STRING
79              
80             =item linetype_bottom => STRING
81              
82             =item linetype_left => STRING
83              
84             =item linetype_right => STRING
85              
86             Overrides the C attribute for each side of the frame specifically.
87             If two line-drawing styles meet at corners they should be drawn correctly if
88             C can combine the line segments, but in other
89             circumstances the corners are drawn as extensions of the top or bottom line,
90             and the left and right lines do not meet it.
91              
92             Any edge's linetype may be set to C to cause that edge not to have a
93             line at all; no extra space will be consumed on that side.
