Detailed Description

Graphic class.

Library: views

A rectangular gauge appears as a rectangle containing another rectangle as in the figure below. This second rectangle is the moving part of the gauge, and is displayed as a flat area. It is attached to three of the four borders of the outer rectangle, and the free end indicates the value.

Accessors\nAccessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods <tt>IlvValueInterface::queryValue()</tt>, <tt>IlvValueInterface::queryValues()</tt>, <tt>IlvValueInterface::changeValue()</tt>, <tt>IlvValueInterface::changeValues()</tt>.\n\n\nThis class inherits the accessors of its superclass \c IlvGauge and adds the following ones:

Name	Type	Equivalent methods
direction	Direction	getDirection(), setDirection()
showBox	Boolean	isBoxShown(), showBox()

Constructor & Destructor Documentation

IlvRectangularGauge()

IlvRectangularGauge::IlvRectangularGauge	(	IlvDisplay *	display,
		const IlvRect &	drawrect,
		IlFloat	min = 0,
		IlFloat	max = 100,
		IlFloat	value = 50,
		IlvDirection	direction = IlvVertical,
		IlBoolean	showBox = IlTrue,
		IlvPalette *	palette = 0
	)

Constructor.

The drawrect parameter indicates the size of the object. The direction parameter indicates the direction of the gauge: it can be set to any of the four directions (IlvBottom, IlvTop, IlvLeft, IlvRight), indicating the position of the minimum value representation, or to IlvVertical (equivalent to IlvBottom) or IlvHorizontal (equivalent to IlvLeft).

Parameters

display	The display instance.
drawrect	Specifies the geometry of the rectangle.
min	The minimum value of the gauge.
max	The maximum value of the gauge.
value	The current value of the gauge.
direction	The direction of the gauge.
showBox	A Boolean value indicating whether to show the gauge's border rectangle or not.
palette	The palette used to draw the graphic object.

Member Function Documentation

bboxRange()

virtual void IlvRectangularGauge::bboxRange ( IlFloat  v1, IlFloat  v2, IlvRect &  rect, const IlvTransformer *  t = 0  ) const

virtual

Returns the rectangle to update when the value of the gauge changes.

Returns

The rectangular region to be updated if the value of the gauge was changing from v1 to v2.

Parameters

v1	Initial value of the gauge.
v2	Future value of the gauge.
rect	Used to return the rectangle to update.
t	The transformer. If it is specified, the graphic object is considered to be drawn through a transformation and the returned rectangle is expressed in the transformed coordinate system.

Implements IlvGauge.

Reimplemented in IlvReliefGauge, and IlvSliderGauge.

boundingBox()

virtual void IlvRectangularGauge::boundingBox ( IlvRect &  bbox, const IlvTransformer *  t = 0  ) const

virtual

Retrieves the bounding box of the graphic object.

Sets bbox, the rectangle reference parameter, to be the bounding box of the object. Since the object can appear within a transformed environment (for example, in a multiview editor), an IlvTransformer object occurs as an optional parameter in order to compute the bounding box in the coordinate system of the transformed environment.

Parameters

bbox	The bounding box to be set.
t	A transformer value or 0 if there is no transformation.

Implements IlvGauge.

draw()

virtual void IlvRectangularGauge::draw ( IlvPort *  dst, const IlvTransformer *  t = 0, const IlvRegion *  clip = 0  ) const

virtual

Draws the graphic object.

Draws the object in the given IlvPort using the transformer t.

Parameters

dst	The destination port this object is drawn onto.
t	The transformer value. If 0, no transformation is performed.
clip	The clipping region, relative to the transformed object, or 0 if none.

Reimplemented from IlvGauge.

drawValue()

virtual void IlvRectangularGauge::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.

Implements IlvGauge.

Reimplemented in IlvReliefGauge, and IlvSliderGauge.

getDirection()

(

)

const

Gets the direction of the gauge.

Returns

isBoxShown()

IlBoolean IlvRectangularGauge::isBoxShown

(

)

const

Tells you if the gauge's border is shown.

An IlBoolean value indicating whether the border rectangle is to be displayed or not.

requestValue()

virtual IlFloat IlvRectangularGauge::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.

Implements IlvGauge.

Reimplemented in IlvSliderGauge.
