Syntax
struct FSizeParam
Remarks
Base structure for size parameters.
Describes a way in which a parent widget allocates available space to its child widgets.
When SizeRule is SizeRule_Auto, the required space is the widget's DesiredSize. When SizeRule is SizeRule_Stretch, the required space is the available space distributed proportionately between peer Widgets. When SizeRule is SizeRule_StretchContent, the required space is widget's content size adjusted proportionally to fit the available space.
Available space is space remaining after all the peers' SizeRule_Auto requirements have been satisfied. The available space is distributed proportionally between the peer widgets depending on the Value property.
FSizeParam cannot be constructed directly - see FStretch, FStretchContent, FAuto, and FAspectRatio
