Struct LayoutGuide
Encapsulates the parameters and results of a layout pass (Measure, Arrange, Render) for a view.
public struct LayoutGuide- Inherited Members
Fields
Anchor
The anchor point that defines the alignment constraint for layout. This point serves as a reference for positioning the view based on alignment. For example, if alignment is set to End, the anchor represents the bottom-right constraint. If alignment is Start, it represents the top-left constraint.
public Point AnchorField Value
ArrangedRect
The final rectangle occupied by the view's border edge box after the Arrange pass.
public Rect ArrangedRectField Value
AvailableSize
The available space for measuring this view's margin box. Used during the Measure pass.
public Size AvailableSizeField Value
CurrentTime
The time of the current animation frame for this view. For Measure/Arrange/Render passes, this may be Zero.
public TimeSpan CurrentTimeField Value
DesiredSize
The desired size of the view's margin box, produced during the Measure pass.
public Size DesiredSizeField Value
Instruments
Instrumentation accessor for zero-alloc logging during layout passes.
public InstrumentsAccessor InstrumentsField Value
MeasureContext
Optional measurement context providing access to platform-specific text metrics and precise size calculations during the Measure pass. If set, text and layout measurements can use font shaping and pixel snapping consistent with the underlying rendering system.
public IMeasureContext? MeasureContextField Value
Pass
Indicates the type of layout pass being performed: Measure, Arrange, or Render.
public LayoutGuide.LayoutPass PassField Value
PreviousTime
The time of the previous animation frame.
public TimeSpan PreviousTimeField Value
RenderContext
Optional rendering context for drawing during the Render pass.
public IContext? RenderContextField Value
XAlign
The horizontal alignment of the view within its allocated space.
public LayoutGuide.Align XAlignField Value
XSize
How the view should size itself horizontally during measurement (exact or at-most).
public LayoutGuide.SizeTo XSizeField Value
YAlign
The vertical alignment of the view within its allocated space.
public LayoutGuide.Align YAlignField Value
YSize
How the view should size itself vertically during measurement (exact or at-most).
public LayoutGuide.SizeTo YSizeField Value
Properties
IsAnimate
Returns true if this guide represents an animation pass.
public bool IsAnimate { get; }Property Value
IsArrange
Returns true if this guide represents an Arrange pass.
public bool IsArrange { get; }Property Value
IsLuminarFlow
Returns true if all four passes are requested (Animate, Measure, Arrange, Render), meaning the view can process the full pipeline in a single DFS walk via View.ForkUpdate.
public bool IsLuminarFlow { get; }Property Value
IsMeasure
Returns true if this guide represents a Measure pass.
public bool IsMeasure { get; }Property Value
IsRender
Returns true if this guide represents a Render pass.
public bool IsRender { get; }
