Syntax
class SWeakWidget : public SWidget
Remarks
Implements a widget that holds a weak pointer to one child widget.
Weak widgets encapsulate a piece of content without owning it. e.g. A tooltip is owned by the hovered widget but displayed by a floating window. That window cannot own the tooltip and must therefore use an SWeakWidget.
