Syntax
class SPanel : public SWidget
Remarks
A Panel arranges its child widgets on the screen.
Each child widget should be stored in a Slot. The Slot describes how the individual child should be arranged with respect to its parent (i.e. the Panel) and its peers Widgets (i.e. the Panel's other children.) For a simple example see StackPanel.
