Detailed Description

Graphic class.

Library: views

This class is kept for compatibility reasons only. The class IlvPolyPointsSelection fills its role in a more general and extensible manner. The IlvPolySelection class is used to fill squares on all the points of an object of type IlvPolyPoints.

Constructor & Destructor Documentation

IlvPolySelection()

IlvPolySelection::IlvPolySelection	(	IlvPolyPoints *	object,
		IlUShort	size = 4,
		IlvMarkerType	marker = IlvMarkerFilledSquare,
		IlvPalette *	palette = 0
	)

Constructor.

The constructor initializes a new IlvPolySelection object. The size of the side of a handle is provided by size. Handles are drawn using an IlvMarker graphic object. This marker is indicated by the marker parameter.

Parameters

object	The object of type IlvPolyPoints.
size	The size of the side of a handle.
marker	The marker type.
palette	The palette of the object.

Member Function Documentation

apply()

void IlvPolySelection::apply ( IlvApplyObject  f, IlAny  arg  )

virtual

Applies a function to an IlvPolyPoints object.

Applies the function f to the referenced IlvPolyPoints object, with the user argument arg.

Parameters

f	The function to be applied.
arg	A user argument.

Reimplemented from IlvGraphic.

applyTransform()

virtual void IlvPolySelection::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.

Implements IlvGraphic.

boundingBox()

virtual void IlvPolySelection::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 IlvGraphic.

contains()

virtual IlBoolean IlvPolySelection::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

p	The point to be tested.
tp	The transformed point obtained by applying the transformer t to the point p.
t	A 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.

draw()

virtual void IlvPolySelection::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.

Implements IlvGraphic.

getObject()

IlvPolyPoints* IlvPolySelection::getObject

(

)

const

Gets an IlvPolyPoints object.

Returns

The IlvPolyPoints used by the object.

getPoint()

void IlvPolySelection::getPoint	(	IlvPoint &	point,
		IlUInt	index
	)		const

Gets a point located at an index.

Parameters

point	Return value holding the point coordinates.
index	The index. The first point has an index of 0.

Returns

In point the coordinates of the point of the referenced IlvPolyPoints located at index index.

getPointIndex()

virtual IlInt IlvPolySelection::getPointIndex ( const IlvPoint &  point, const IlvTransformer *  t  ) const

virtual

Gets a marker index containing a point.

Parameters

point	The point specifying the first marker.
t	The transformer value.

Returns

The index of the first marker that contains point, when this object is drawn by the transformer t. If no such point exists, it returns -1.

getSize()

IlUShort IlvPolySelection::getSize

(

)

const

Gets the marker size.

Returns

The size of the markers drawn around the points defining the referenced IlvPolyPoints.

setMode()

virtual void IlvPolySelection::setMode ( IlvDrawMode  mode )

virtual

Sets the drawing mode of the object temporarily.

Changing the IlvDrawMode attribute of an object is considered a temporary operation. You have to set the mode to its default value when you no longer need another mode different from the value IlvModeSet. The drawing mode information is passed to the palette of the graphic object (see the IlvPalette::setOverwrite() method for more details).

Parameters

mode	The drawing mode to be set.

Reimplemented from IlvSimpleGraphic.

setObject()

void IlvPolySelection::setObject

(

IlvPolyPoints *

object

)

Sets an IlvPolyPoints object.

Sets the IlvPolyPoints used by the object.

setPoint()

void IlvPolySelection::setPoint	(	const IlvPoint &	point,
		IlUInt	index
	)

Sets a point located at an index.

Modifies the point of the referenced IlvPolyPoints at index index.

Parameters

point	The point to be set.
index	The index.

setSize()

void IlvPolySelection::setSize

(

IlUShort

size

)

Sets the marker size.

Sets the size of the sides of the markers drawn around the points defining the referenced IlvPolyPoints.

Parameters

size	The size of the sides of the markers.

translatePoint()

void IlvPolySelection::translatePoint	(	const IlvPoint &	delta,
		IlUInt	index
	)

Translates a point located at an index.

Translates the point of the referenced IlvPolyPoints at index index.

Parameters

delta	The translation factor.
index	The index. An index set to 0 indicates the first point.
