UMG Size Box

Properties

Name	Type	Category	In the details panel	From Blueprint	Description
`Padding`	`FMargin`	SizeBox	yes	`SetPadding`
`bOverrideWidth`	`bool`	SizeBox	yes	`SetOverrideWidth`
`WidthOverride`	`float`	SizeBox	yes	`SetWidthOverride`
`bOverrideHeight`	`bool`	SizeBox	yes	`SetOverrideHeight`
`HeightOverride`	`float`	SizeBox	yes	`SetHeightOverride`
`MinDesiredSize`	`FVector2D`	SizeBox	yes	`SetMinDesiredSize`
`MaxDesiredSize`	`FVector2D`	SizeBox	yes	`SetMaxDesiredSize`
`MinAspectRatio`	`float`	SizeBox	yes	`SetMinAspectRatio`	Width-over-height bounds on the CONTENT's rect, as SBox applies them: the box itself is sized by the rules above, and a content rect whose ratio falls outside these is shrunk on one axis until it does not, then re-aligned inside the space it was offered.
`MaxAspectRatio`	`float`	SizeBox	yes	`SetMaxAspectRatio`

Functions

Function	Kind	Description
`void ClearHeightOverride()`	callable	Clear Height Override
`void ClearMaxAspectRatio()`	callable	Clear Max Aspect Ratio
`void ClearMaxDesiredHeight()`	callable	Clear Max Desired Height
`void ClearMaxDesiredWidth()`	callable	Clear Max Desired Width
`void ClearMinAspectRatio()`	callable	Clear Min Aspect Ratio
`void ClearMinDesiredHeight()`	callable	Clear Min Desired Height
`void ClearMinDesiredWidth()`	callable	Clear Min Desired Width
`void ClearWidthOverride()`	callable	USizeBox's per-axis accessors. The two bounds are stored as one FVector2D apiece here, which is the same four numbers with half the fields; these name the axis the way UMG does, and Clear is "put that axis back to zero", which is how this class already spells "no opinion".
`float GetMaxDesiredHeight()`	pure	Get Max Desired Height
`float GetMaxDesiredWidth()`	pure	Get Max Desired Width
`float GetMinDesiredHeight()`	pure	Get Min Desired Height
`float GetMinDesiredWidth()`	pure	Get Min Desired Width
`bool IsMaxAspectRatioOverride()`	pure	Is Max Aspect Ratio Override
`bool IsMinAspectRatioOverride()`	pure	Is Min Aspect Ratio Override
`void SetHeightOverride(float Value)`	callable	Set Height Override
`void SetMaxAspectRatio(float Value)`	callable	Set Max Aspect Ratio
`void SetMaxDesiredHeight(float InMaxDesiredHeight)`	callable	Set Max Desired Height
`void SetMaxDesiredSize(FVector2D Value)`	callable	Set Max Desired Size
`void SetMaxDesiredWidth(float InMaxDesiredWidth)`	callable	Set Max Desired Width
`void SetMinAspectRatio(float Value)`	callable	Set Min Aspect Ratio
`void SetMinDesiredHeight(float InMinDesiredHeight)`	callable	Set Min Desired Height
`void SetMinDesiredSize(FVector2D Value)`	callable	Set Min Desired Size
`void SetMinDesiredWidth(float InMinDesiredWidth)`	callable	Set Min Desired Width
`void SetOverrideHeight(bool Value)`	callable	Set Override Height
`void SetOverrideWidth(bool Value)`	callable	Set Override Width
`void SetPadding(FMargin Value)`	callable	Set Padding
`void SetWidthOverride(float Value)`	callable	Set Width Override

Compared with UMG

Every Blueprint-facing member of the UMG class, and where it went. adopt: same name, same meaning. map: here under another name or on another type. reject: deliberately absent, with the reason.

UMG	Member	Status	Here	Note
`USizeBox`	`WidthOverride`	adopt	`WidthOverride`	Its override bit is bOverrideWidth here; UMG spells it bOverride_WidthOverride.
`USizeBox`	`HeightOverride`	adopt	`HeightOverride`
`USizeBox`	`MinDesiredWidth`	map	`MinDesiredSize`	One FVector2D holds both axes; zero on an axis is that axis's 'no opinion', where UMG spends a separate bOverride_ bit. GetMinDesiredWidth/SetMinDesiredWidth/ClearMinDesiredWidth exist under UMG's names.
`USizeBox`	`MinDesiredHeight`	map	`MinDesiredSize`	The y of the same pair.
`USizeBox`	`MaxDesiredWidth`	map	`MaxDesiredSize`	As MinDesiredWidth.
`USizeBox`	`MaxDesiredHeight`	map	`MaxDesiredSize`	The y of the same pair.
`USizeBox`	`MinAspectRatio`	adopt	`MinAspectRatio`	Zero means not set, the convention the two size bounds on this class already use. Applied to the CONTENT's rect in arrange, as SBox does, not to the box's own measured size.
`USizeBox`	`MaxAspectRatio`	adopt	`MaxAspectRatio`	Tested before the minimum, so a pair that crosses resolves to the maximum.
`USizeBox`	`SetWidthOverride`	adopt	`SetWidthOverride`
`USizeBox`	`ClearWidthOverride`	adopt	`ClearWidthOverride`
`USizeBox`	`SetHeightOverride`	adopt	`SetHeightOverride`
`USizeBox`	`ClearHeightOverride`	adopt	`ClearHeightOverride`
`USizeBox`	`SetMinDesiredWidth`	adopt	`SetMinDesiredWidth`
`USizeBox`	`ClearMinDesiredWidth`	adopt	`ClearMinDesiredWidth`
`USizeBox`	`SetMinDesiredHeight`	adopt	`SetMinDesiredHeight`
`USizeBox`	`ClearMinDesiredHeight`	adopt	`ClearMinDesiredHeight`
`USizeBox`	`SetMaxDesiredWidth`	adopt	`SetMaxDesiredWidth`
`USizeBox`	`ClearMaxDesiredWidth`	adopt	`ClearMaxDesiredWidth`
`USizeBox`	`SetMaxDesiredHeight`	adopt	`SetMaxDesiredHeight`
`USizeBox`	`ClearMaxDesiredHeight`	adopt	`ClearMaxDesiredHeight`
`USizeBox`	`SetMinAspectRatio`	adopt	`SetMinAspectRatio`
`USizeBox`	`ClearMinAspectRatio`	adopt	`ClearMinAspectRatio`
