public sealed class SliderNode : Hex1bNode

Inheritance

Object → Hex1bNode → SliderNode

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; }

LargeStepPercent

The large step as a percentage of the range (for PageUp/PageDown).

Returns: Double

public double LargeStepPercent { get; set; }

Maximum

The maximum value of the range.

Returns: Double

public double Maximum { get; set; }

Minimum

The minimum value of the range.

Returns: Double

public double Minimum { get; set; }

Percentage

Gets the current value as a percentage (0.0 to 1.0) of the range.

Returns: Double

public double Percentage { get; }

SourceWidget

The source widget for creating typed event args.

Returns: SliderWidget

public SliderWidget? SourceWidget { get; set; }

Step

The step increment for keyboard navigation. Null means 1% of range.

public double? Step { get; set; }

Value

The current value of the slider.

Returns: Double

public double Value { 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)

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

SliderNode maintains the current value and handles keyboard/mouse input for adjusting the value. The value is preserved across reconciliation cycles.

The slider renders as a horizontal track with a handle (knob) that indicates the current position within the range.
