◆ can_wrap()

virtual bool gui2::rich_label::can_wrap ( ) const

inlineoverridevirtual

Can the widget wrap.

When a widget can wrap it can reduce its width by increasing its height. When a layout is too wide it should first try to wrap and if that fails it should check the vertical scrollbar status. After wrapping the height might (probably will) change so the layout engine needs to recalculate the height after wrapping.
