Syntax

public static class LayoutUtility

Methods

GetFlexibleHeight(RectTransform)

Returns the flexible height of the layout element.

Declaration

public static float GetFlexibleHeight(RectTransform rect)

Parameters

Type	Name	Description
RectTransform	rect	The RectTransform of the layout element to query.

Returns

Type	Description
float

Remarks

All components on the GameObject that implement the ILayoutElement are queried. The one with the highest priority which has a value for this setting is used. If multiple componets have this setting and have the same priority, the maximum value out of those is used.

GetFlexibleSize(RectTransform, int)

Returns the flexible size of the layout element.

Declaration

public static float GetFlexibleSize(RectTransform rect, int axis)

Parameters

Type	Name	Description
RectTransform	rect	The RectTransform of the layout element to query.
int	axis	The axis to query. This can be 0 or 1.

Returns

Type	Description
float

Remarks

All components on the GameObject that implement the ILayoutElement are queried. The one with the highest priority which has a value for this setting is used. If multiple componets have this setting and have the same priority, the maximum value out of those is used.

GetFlexibleWidth(RectTransform)

Returns the flexible width of the layout element.

Declaration

public static float GetFlexibleWidth(RectTransform rect)

Parameters

Type	Name	Description
RectTransform	rect	The RectTransform of the layout element to query.

Returns

Type	Description
float

Remarks

All components on the GameObject that implement the ILayoutElement are queried. The one with the highest priority which has a value for this setting is used. If multiple componets have this setting and have the same priority, the maximum value out of those is used

GetLayoutProperty(RectTransform, Func<ILayoutElement, float>, float)

Gets a calculated layout property for the layout element with the given RectTransform.

Declaration

public static float GetLayoutProperty(RectTransform rect, Func<ILayoutElement, float> property, float defaultValue)

Parameters

Type	Name	Description
RectTransform	rect	The RectTransform of the layout element to get a property for.
Func<ILayoutElement, float>	property	The property to calculate.
float	defaultValue	The default value to use if no component on the layout element supplies the given property

Returns

Type	Description
float	The calculated value of the layout property.

GetLayoutProperty(RectTransform, Func<ILayoutElement, float>, float, out ILayoutElement)

Gets a calculated layout property for the layout element with the given RectTransform.

Declaration

public static float GetLayoutProperty(RectTransform rect, Func<ILayoutElement, float> property, float defaultValue, out ILayoutElement source)

Parameters

Type	Name	Description
RectTransform	rect	The RectTransform of the layout element to get a property for.
Func<ILayoutElement, float>	property	The property to calculate.
float	defaultValue	The default value to use if no component on the layout element supplies the given property
ILayoutElement	source	Optional out parameter to get the component that supplied the calculated value.

Returns

Type	Description
float	The calculated value of the layout property.

GetMinHeight(RectTransform)

Returns the minimum height of the layout element.

Declaration

public static float GetMinHeight(RectTransform rect)

Parameters
