Public Member Functions
void	setProperties (SliderProperties properties)
	Assigns minimum, maximum, and quantization stepping properties.
void	setRange (float min, float max)
	Sets the absolute functional minimum and maximum selection boundaries.
void	setStyle (const SliderStyle &style)
	Overrides the visual style parameters for the track and slider handles.
void	setTrackHeight (float height)
void	setThumbWidth (float width)
void	setThumbHeight (float height)
void	setThumbColor (const Color &color)
void	setFillColor (const Color &color)
void	setTrackColor (const Color &color)
float	applyStep (float value) const
	Snaps a raw value to the nearest incremental step boundary configuration.
void	setValue (float value)
	Sets the tracking selection value directly, applying steps and clamps.
const SliderProperties &	getProperties () const
const SliderStyle &	getStyle () const
const float &	getValue () const
	Gets the current stepped, clamped value of the slider.
void	setFocused (bool focused) override
	Sets whether this node is currently focused.
void	measure (UIConstraints constraints) override
	Pass 1 of the layout engine: Crawls branches recursively to compute base display boundaries requested by child assets.
void	arrange (const Rect< float > &rect) override
	Pass 2 of the layout engine: Evaluates layout adjustments to pin final screen coordinate values to the tree structures.
void	handleEvent (const UIEvent &event) override
	Routes interaction updates, translating drag motions and directional navigations.
void	render (UICanvas &canvas) const override
	Draws the slider track background, active fill bar, and handle quad.
bool	consumesDirectionalInput () const override
	Dictates whether this widget captures directional inputs instead of passing them to focus navigation.
bool	isFocusable () const override
	Dictates if keyboard selection trackers or gamepad vectors can snap control focuses onto this item.
void	onChange (std::function< void(float)> callback)
	Registers a function callback to execute whenever the slider value mutations occur.
bool	hitTest (Vec2f point) const override
	Computes true if a vector coordinate sits inside the spatial arrangement bounding tracking layout box.
Public Member Functions inherited from Flint::UINode

	Get the node's relative local position.
void	setSize (Vec2f size)
	Assigns a manual static override layout budget footprint dimensions limit.
Vec2f	getSize () const
	Get the node's base size.
void	setVisible (bool visible)
	Sets widget visibility.
void	setEnabled (bool enabled)
	Enables or disables user interaction for this widget.

	Sets a unique string identifier for this node.
const std::string &	getId () const
	Gets the unique lookup ID string of this node.
const Rect< float > &	getLayoutRect () const
	Gets the final screen-space bounding box calculated during the arrange pass.
bool	isVisible () const
bool	isEnabled () const
Vec2f	getDesiredSize () const
	Get the node's requested size from the measure pass.
const std::vector< std::unique_ptr< UINode > > &	getChildren () const
	Get the list of this node's child nodes.
void	setText (std::string text)
	Sets the text content for widgets that display text.
const std::string &	getText () const
	Gets the current text content of the widget.
void	setFontSize (uint16_t fontSize)

Color	getColor () const
virtual void	setNormalColor (Color color)
	Sets the base color of the widget.
virtual void	setActiveColor (Color color)
	Sets visual colors used when inputs hover across or lock selections on the widget container.
void	setFont (std::string name)
	Assigns a custom typography description token mapping back to cached font elements.
void	setFontWeight (uint16_t weight)
	Assigns thickness parameters across structural type vectors (e.g., 400 for regular, 700 for bold).
void	setTextOpticalBias (float bias)
float	getTextOpticalBias () const
bool	isFocused () const
void	setHorizontalAlign (UIAlign align)
void	setVerticalAlign (UIAlign align)
UIAlign	getHorizontalAlign () const
