.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This subclass of Tickit::Widget::LinearBox distributes its children in a
vertical column. Its width will be the width of the widest child, and its
height will be the sum of the heights of all the children, plus the
inter-child spacing.
.PP
Optionally, if given a non-zero spacing between child widgets and a style to
draw in, a horizontal dividing line will be drawn between each child.
.SH "STYLE"
.IX Header "STYLE"
The default style pen is used as the widget pen. The following style pen
prefixes are also used:
.IP "line => \s-1PEN\s0" 4
.IX Item "line => PEN"
\&\fISince version 0.52.\fR
.Sp
The pen used to render a dividing line between child widgets.
.PP
Note that while the widget pen is mutable and changes to it will result in
immediate redrawing, any changes made will be lost if the widget style is
changed.
.PP
The following style keys are used:
.IP "spacing => \s-1INT\s0" 4
.IX Item "spacing => INT"
The number of lines of spacing between children
.IP "line_style => \s-1INT\s0" 4
.IX Item "line_style => INT"
\&\fISince version 0.52.\fR
.Sp
If set, the style to draw a dividing line between each child widget. Must be
one of the \f(CW\*(C`LINE_*\*(C'\fR constants from Tickit::RenderBuffer.
