	)

Constructor.

The bounding box of the new scale depends on its origin and size, but also on the direction and position parameters. The origin of the scale must not be confused with the origin of the rectangle that contains it, which is located at the upper-left corner of its bounding box.

Parameters

display	The display where this object is created.
orig	The origin of the scale.
size	The dimension of the scale's main axis: the width of the scale if it is horizontal, and its height if it is vertical.
format	The `printf()` format of the step labels.
min	The minimum value of the scale.
max	The maximum value of the scale.
direction	The direction of the scale. Valid values are `IlvVertical` (bottom to top) and `IlvHorizontal` (left to right).
position	The position of the scale. Valid values depend on direction: `IlvLeft` and `IlvRight` for a vertical scale, `IlvTop` and `IlvBottom` for a horizontal scale.
steps	The number of major ticks to be drawn, which can be `0` for no scales.
substeps	The number of minor ticks displayed between major ones.
stepsize	The major tick mark size.
substepsize	The minor tick mark size.
palette	The palette associated with this object.

The parameter size specifies the dimension of the scale in its main axis (width for horizontal scale and height for a vertical scale). The direction of the scale is indicated by direction: valid values are IlvVertical (bottom to top) and IlvHorizontal (left to right). The position of the scale is specified by position. Valid values depend on direction: IlvLeft and IlvRight for a vertical scale, IlvTop and IlvBottom for a horizontal scale.

orig	The origin of the scale.
size	The dimension of the scale's main axis.

Member Function Documentation

◆ applyTransform()

virtual void IlvRectangularScale::applyTransform ( const IlvTransformer * t )

virtual

Applies a transformation function to the graphic object.

Applies the transformer t to the shape of the object. Unless the transformation is a scaling operation, the result of applying it to certain objects can be insignificant. For example, applying a non-scaling transformer to an IlvRectangle object is meaningless, since the rectangle remains a rectangle. On the other hand, meaningful transformations can be applied to objects that are instances of types such as IlvLine or IlvPolyPoints.

Note: applyTransform() is one of the most important method to be rewritten for classes derived from IlvGraphic, since it is called by the resize(), move(), moveResize(), scale(), etc., methods.

Parameters

t	The transformer value. If `0`, no transformation is performed.

Reimplemented from IlvScale.

◆ areLabelsCentered()

IlBoolean IlvRectangularScale::areLabelsCentered ( ) const

Gets the 'centered labels' flag.

Returns: IlTrue if the scale draws its labels between the markers, or IlFalse if it draws each label with its corresponding marker.

See also: centerLabels().

◆ boundingBox()

virtual void IlvRectangularScale::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 IlvScale.

◆ centerLabels()

void IlvRectangularScale::centerLabels ( IlBoolean flag )

Sets the 'centered labels' flag.

Parameters

flag	The new value of the the 'centered labels' flag of this scale object.

See also: areLabelsCentered().

◆ doesDrawOverlappingLabels()

IlBoolean IlvRectangularScale::doesDrawOverlappingLabels ( ) const

virtual

Draws the graphic object.

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

Parameters

	)		const

virtual

Draws a label.
