Description

CMParentColorChanged is an overridden method in TScrollBox used to handle a CM_PARENTCOLORCHANGED message received for the control. It calls the UpdateParentColorChange method to include or exclude csOpaque in the ControlStyle property; csOpaque is included if either ParentColor or ParentBackground is set to True. Otherwise, the value is excluded from ControlStyle.

CMParentColorChanged calls the inherited method to update the Color property when ParentColor is enabled.
