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.
IlvCircularGauge, IlvReliefGauge, IlvSliderGauge. | 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).
| 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. |
|
virtual |
Returns the rectangle to update when the value of the gauge changes.
| 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.
|
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.
| bbox | The bounding box to be set. |
| t | A transformer value or 0 if there is no transformation. |
Implements IlvGauge.
|
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.
| dst | The destination port. |
| t | The transformer value. If 0, no transformation is performed. |
| clip | The clipping region, or 0 if none. |
Reimplemented from IlvGauge.
|
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).
| dst | The destination port. |
| t | The transformer to apply to the drawing. |
| clip | The clipping region. |
Implements IlvGauge.
Reimplemented in IlvReliefGauge, and IlvSliderGauge.
| IlvDirection IlvRectangularGauge::getDirection | ( | ) | const |
Gets the direction of the gauge.
| IlBoolean IlvRectangularGauge::isBoxShown | ( | ) | const |
Tells you if the gauge's border is shown.
IlBoolean value indicating whether the border rectangle is to be displayed or not.

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