CheckboxNode

Namespace: Hex1b

Assembly: Hex1b.dll

Render node for CheckboxWidget.

public sealed class CheckboxNode : Hex1bNode

Inheritance

Object → Hex1bNode → CheckboxNode

Properties

IsFocusable

Returns true if this node can receive focus.

Returns: Boolean

public override bool IsFocusable { get; }

IsFocused

Gets or sets whether this node is currently focused. Only meaningful for focusable nodes (where IsFocusable is true).

Returns: Boolean

public override bool IsFocused { get; set; }

IsHovered

Gets or sets whether the mouse is currently hovering over this node. Set by Hex1bApp based on mouse position during each frame. Only set on focusable nodes (tracked via FocusRing hit testing).

Returns: Boolean

public override bool IsHovered { get; set; }

Label

Optional label displayed after the checkbox.

Returns: String

public string? Label { get; set; }

SourceWidget

The source widget for typed event args.

Returns: CheckboxWidget

public CheckboxWidget? SourceWidget { get; set; }

State

The current state of the checkbox. The instance can either be owned by the framework (when no was supplied) or by a composite parent (when it was). Either way, toggle gestures mutate in place so external observers see the change immediately.

Returns: CheckboxState

public CheckboxState State { get; set; }

ToggledCallback

Callback for the toggle event.

Returns: Func<InputBindingActionContext, Task>

public Func<InputBindingActionContext, Task>? ToggledCallback { get; set; }
