If the border is disabled, the field will be underlined, provided the terminal supports it. .PP The value of \fB\s-1VALUE\s0\fR should be an array reference when in multiple selection mode. Otherwise it should either undef or an integer. .SS "draw" .IX Subsection "draw" .Vb 1 \& $lb\->draw($mwh, 1); .Ve .PP The draw method renders the list box in its current state. This requires a valid handle to a curses window in which it will render itself.
