Detailed Description

Graphic class.

Library: views

A filled circular gauge displays the value it holds by means of a filled arc that fits in an ellipse as in the following figure.

- IlvFilledCircularGauge -

See also: IlvRectangularGauge, IlvReliefGauge, IlvSliderGauge.

Constructor & Destructor Documentation

◆ IlvFilledCircularGauge()

IlvFilledCircularGauge::IlvFilledCircularGauge	(	IlvDisplay *	display,
		const IlvRect &	drawrect,
		IlFloat	min = `0`,
		IlFloat	max = `100`,
		IlFloat	value = `50`,
		IlFloat	start = `0`,
		IlFloat	range = `180`,
		IlvPalette *	palette = `0`
	)

Constructor.

Parameters

display	The display instance.
drawrect	Specifies the size of the ellipse, which is the size of the graphic object.
min	The minimum value of the gauge.
max	The maximum value of the gauge.
value	The current value of the gauge.
start	The starting angle of the arc.
range	The angle range of the arc.
palette	The palette used to draw the graphic object.

Member Function Documentation

◆ drawValue()

virtual void IlvFilledCircularGauge::drawValue	(	IlvPort *	dst,
		const IlvTransformer *	t = `0`,
		const IlvRegion *	clip = `0`
	)		const

virtual

Performs the drawing representing the current value of the gauge.

Called by the member function draw() and interactors that connect to it. Draws the part of the gauge that indicates its value (such as the hand of a watch).

Parameters

dst	The destination port.
t	The transformer to apply to the drawing.
clip	The clipping region.

Reimplemented from IlvCircularGauge.

◆ requestValue()

virtual IlFloat IlvFilledCircularGauge::requestValue	(	const IlvPoint &	point,
		const IlvTransformer *	t,
		IlBoolean &	connect
	)		const

virtual

Returns the value of the gauge associated with a given point.

Returns: the value stored in this gauge if its moving part was at the specified location. If the point is outside the object bounding box, the function returns a reasonable value (the closest point on the object bounding box is considered).

Parameters

point	The point. If a transformer is specified, the point is considered to be transformed, i.e. expressed in the transformed coordinate system.
t	The transformer.
connect	If `IlTrue`, the provided point indicates a connection to the gauge. Mostly, this means that the point is located on the moving part of the gauge.
