Description

TControlChildSizing is a TPersistent descendant which provides properties and methods used to layout, align, and resize child controls relative to their parent. Properties are provided which define the horizontal and vertical spacing between controls, the preferred direction controls are aligned, and whether controls are scaled to fit in the parent control.

See TChildControlResizeStyle and TControlChildrenLayout for details about the enumeration values used in the properties.
