Struct FocusBorderLayer<TView, TChild>

Namespace

Xui.Core.UI.Layer

Assembly

Xui.Core.dll

A BorderLayer<TChild> variant that switches border color when the host view has keyboard focus. All layout and rendering is delegated to an inner BorderLayer<TChild>; only Render(TView, IContext) swaps the color, and OnFocus(TView) / OnBlur(TView) request a repaint.

public struct FocusBorderLayer<TView, TChild> : ILayer<TView> where TView : ILayerHost where TChild : struct, ILayer<TView>

Methods

Animate(TView, TimeSpan, TimeSpan)

Advances time-based state (animations, blinking cursors, etc.).

public void Animate(TView view, TimeSpan previousTime, TimeSpan currentTime)

Parameters

view TView

previousTime TimeSpan

currentTime TimeSpan

Arrange(TView, Rect, IMeasureContext)

Finalises position and size within rect.

public void Arrange(TView view, Rect rect, IMeasureContext context)

Parameters

view TView

rect Rect

context IMeasureContext

Measure(TView, Size, IMeasureContext)

Returns the desired border-edge size given the available space.

public Size Measure(TView view, Size availableSize, IMeasureContext context)

Parameters

view TView

availableSize Size

context IMeasureContext

Returns

Size

OnBlur(TView)

Called when the host view loses keyboard focus.

public void OnBlur(TView view)

Parameters

view TView

OnChar(TView, ref KeyEventRef)

Handles a character input event while the host view has focus.

public void OnChar(TView view, ref KeyEventRef e)

Parameters

view TView

e KeyEventRef

OnFocus(TView)

Called when the host view gains keyboard focus.

public void OnFocus(TView view)

Parameters

view TView

OnKeyDown(TView, ref KeyEventRef)

Handles a key-down event while the host view has focus.

public void OnKeyDown(TView view, ref KeyEventRef e)

Parameters

view TView

e KeyEventRef

OnPointerEvent(TView, ref PointerEventRef, EventPhase)

Handles a pointer event in the given dispatch phase.

public void OnPointerEvent(TView view, ref PointerEventRef e, EventPhase phase)

Parameters

view TView

e PointerEventRef

phase EventPhase

Render(TView, IContext)

Draws content. Called after Arrange.

public void Render(TView view, IContext context)

Parameters

view TView

context IContext

Update(TView, ref LayoutGuide)

Drives one or more layout passes. Mirrors Update(LayoutGuide). The default per-pass methods are preferred for clarity; override this only when a single-DFS LuminarFlow traversal is needed (leaf layers or single-child-stretch containers).

public void Update(TView view, ref LayoutGuide guide)

Parameters

view TView

guide LayoutGuide
