The ResetStyleDefaults method restores the style settings which depend on the current paint scheme. Specifically, the method calls the BarManagerProperties.ResetStyleDefaults method, which sets the BarManagerProperties.AllowLinkLighting property to a default value according to the paint scheme.
This method is automatically called at design time when you change the current paint scheme via the PaintStyleName or LookAndFeel properties. At runtime, you may want to call this method manually after changing the paint scheme to reset dependent settings.
