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.

Constructor & Destructor Documentation

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
displayThe display instance.
drawrectSpecifies the geometry of the rectangle.
minThe minimum value of the gauge.
maxThe maximum value of the gauge.
valueThe current value of the gauge.
directionThe direction of the gauge.
showBoxA Boolean value indicating whether to show the gauge's border rectangle or not.
paletteThe palette used to draw the graphic object.

Member Function Documentation

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
v1Initial value of the gauge.
v2Future value of the gauge.
rectUsed to return the rectangle to update.
tThe 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.

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. When there is no transformation, t is set to 0.

Parameters
bboxThe bounding box to be set.
tA transformer value or 0 if there is no transformation.

Implements IlvGauge.

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 which might have the value 0. The clip parameter, which can also be 0, represents the clipping region relative to the transformed object.

Parameters
dstThe destination port.
tThe transformer value. If 0, no transformation is performed.
clipThe clipping region, or 0 if none.

Reimplemented from IlvGauge.

virtual void IlvRectangularGauge::drawValue ( IlvPort ,
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
dstThe destination port.
tThe transformer to apply to the drawing.
clipThe clipping region.

Implements IlvGauge.

Reimplemented in IlvReliefGauge, and IlvSliderGauge.

IlvDirection IlvRectangularGauge::getDirection ( ) const

Gets the direction of the gauge.

Returns
The direction of this gauge.
IlBoolean IlvRectangularGauge::isBoxShown ( ) const

Tells you if the gauge's border is shown.

Returns
An IlBoolean value indicating whether the border rectangle is to be displayed or not.
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
pointThe point. If a transformer is specified, the point is considered to be transformed, i.e. expressed in the transformed coordinate system.
tThe transformer.
connectIf 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.

virtual void IlvRectangularGauge::setColorPattern ( IlvColorPattern pattern)
virtual

Sets the color pattern of the object.

Sets the color pattern of the object.

virtual void IlvRectangularGauge::setFillStyle ( IlvFillStyle  style)
virtual

Sets the fill style of the object.

Parameters
styleThe new fill style.

Reimplemented from IlvSimpleGraphic.

virtual void IlvRectangularGauge::setGradientPattern ( IlvGradientPattern pattern)
virtual

Sets the gradient pattern of the object.

Sets the gradient pattern of the object.

Parameters
patternThe new gradient pattern.

Reimplemented from IlvSimpleGraphic.

void IlvRectangularGauge::showBox ( IlBoolean  flag)

Sets the visibility of the gauge's border.

Sets the visibility of the border of the rectangle to show.

Parameters
showA Boolean value indicating whether to show the gauge's border rectangle or not.
