ToggleSwitchNode

Namespace: Hex1b

Assembly: Hex1b.dll

A horizontal toggle switch node that renders options as adjacent per-option chips and allows selection via left/right arrow keys or mouse click. Selection state is owned by this node and preserved across reconciliation.

public sealed class ToggleSwitchNode : Hex1bNode

Inheritance

Object → Hex1bNode → ToggleSwitchNode

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; }

Options

The available options for the toggle switch.

Returns: IReadOnlyList<String>

public IReadOnlyList<string> Options { get; set; }

SelectedIndex

The currently selected option index.

Returns: Int32

public int SelectedIndex { get; set; }

SelectedOption

Gets the currently selected option, or null if no options exist.

Returns: String

public string? SelectedOption { get; }

SourceWidget

The source widget that was reconciled into this node.

Returns: ToggleSwitchWidget

public ToggleSwitchWidget? SourceWidget { get; set; }

Methods

ConfigureDefaultBindings(InputBindingsBuilder)

Configures the default input bindings for this node type. Override in derived classes to add default key bindings. These bindings can be inspected and modified by the user's callback.

Parameters:

• bindings (InputBindingsBuilder): The builder to add bindings to.

public override void ConfigureDefaultBindings(InputBindingsBuilder bindings)

HandleMouseClick(int, int, Hex1bMouseEvent)

Handles mouse click by selecting the option whose chip contains the click.

Parameters:

• localX (Int32):
• localY (Int32):
• mouseEvent (Hex1bMouseEvent):

Returns: InputResult

public override InputResult HandleMouseClick(int localX, int localY, Hex1bMouseEvent mouseEvent)

MeasureCore(Constraints)

Override this method to implement measuring logic for this node.

Parameters:

• constraints (Constraints):

Returns: Size

protected override Size MeasureCore(Constraints constraints)

Render(Hex1bRenderContext)

Renders the node to the given context.

Parameters:

• context (Hex1bRenderContext):

public override void Render(Hex1bRenderContext context)

Remarks

Each option occupies 1 + label_display_width + 1 cells (a single padding cell on each side of the label) and is painted in its own colours — the selected option gets the /

pair (depending on whether the toggle has focus), and the unselected options get the . There is no separator glyph between options.
