Detailed Description

Graphic class.

Library: views

An IlvRectangle object appears as an outlined rectangle.

Note
align="center"The inherited boundingBox member function of IlvRectangle does not take into account the line-width parameter set in the palette object it uses.

Constructor & Destructor Documentation

◆ IlvRectangle()

IlvRectangle::IlvRectangle ( IlvDisplay display,
const IlvRect drawrect,
IlvPalette palette = 0 
)

Constructor.

Parameters
displayThe display instance.
drawrectSpecifies the geometry of the rectangle.
paletteThe palette used to draw the graphic object.

Member Function Documentation

◆ applyTransform()

virtual void IlvRectangle::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
tThe transformer value. If 0, no transformation is performed.

Implements IlvGraphic.

Reimplemented in IlvViewRectangle.

◆ boundingBox()

virtual void IlvRectangle::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
bboxThe bounding box to be set.
tA transformer value or 0 if there is no transformation.

Implements IlvGraphic.

◆ contains()

virtual IlBoolean IlvRectangle::contains ( const IlvPoint p,
const IlvPoint tp,
const IlvTransformer t = 0 
) const
virtual

Checks whether a point is in the object.

Checks whether the coordinates are located in the shape of this object. A transformation parameter allows you to use the view's coordinate system for this test.

Parameters
pThe point to be tested.
tpThe transformed point obtained by applying the transformer t to the point p.
tA transformer value, or 0 if there is no transformation.
Returns
IlTrue when the point p lies inside the outline of the object.

Reimplemented from IlvGraphic.

Reimplemented in IlvFilledRectangle.

◆ draw()

virtual void IlvRectangle::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
dstThe destination port this object is drawn onto.
tThe transformer value. If 0, no transformation is performed.
clipThe clipping region, relative to the transformed object, or 0 if none.

Implements IlvGraphic.

Reimplemented in IlvShadowRectangle, IlvShadowLabel, IlvFilledRoundRectangle, IlvRoundRectangle, IlvReliefLabel, IlvFilledRectangle, IlvGridRectangle, IlvViewRectangle, IlvReliefDiamond, and IlvReliefRectangle.
