Detailed Description

A specialized LookAndFeel class for drawing curve-shaped rotary sliders.

This LookAndFeel renders a rotary slider as a power-scale curve instead of a standard arc. The curve shape can represent a parameter's response curve visually. It supports both active/inactive states and bipolar values.

Constructor & Destructor Documentation

◆ ~CurveLookAndFeel()

virtual CurveLookAndFeel::~CurveLookAndFeel ( )

inlinevirtual

Destructor.

Member Function Documentation

◆ drawCurve()

void CurveLookAndFeel::drawCurve	(	Graphics &	g,
		Slider &	slider,
		int	x,
		int	y,
		int	width,
		int	height,
		bool	active,
		bool	bipolar )

Draws the power-scale curve for the slider.

Parameters

g	The Graphics context.
slider	Reference to the Slider being drawn.
x	The X coordinate of the curve area.
y	The Y coordinate of the curve area.
width	The width of the curve area.
height	The height of the curve area.
active	True if the slider is active (enabled).
bipolar	True if the slider value is bipolar (e.g., can be negative).

◆ drawRotarySlider()

void CurveLookAndFeel::drawRotarySlider	(	Graphics &	g,
		int	x,
		int	y,
		int	width,
		int	height,
		float	slider_t,
		float	start_angle,
		float	end_angle,
		Slider &	slider )

override

Draws a rotary slider with a curve-shaped indicator.

Parameters

g	The Graphics context.
x	The X coordinate of the slider's bounding box.
y	The Y coordinate of the slider's bounding box.
width	The width of the slider's bounding box.
height	The height of the slider's bounding box.
slider_t	The slider's current normalized value (0 to 1).
start_angle	The start angle for the rotary slider (not used for this curve).
end_angle	The end angle for the rotary slider (not used for this curve).
slider	Reference to the slider being drawn.

◆ instance()

static CurveLookAndFeel * CurveLookAndFeel::instance ( )

inlinestatic

Gets the singleton instance of CurveLookAndFeel.

Returns: Pointer to the singleton instance.
