Constructor & Destructor Documentation

§ IlvListLabel() [1/2]

IlvListLabel::IlvListLabel ( IlvDisplay display,
const IlvPoint position,
IlUInt  count,
const char *const *  labels,
IlvPalette palette = 0 
)

Initializes a new IlvListLabel from an array of strings.

Parameters
displayThe display instance.
positionThe position of the graphic object bounding box.
countThe number of strings in the array.
labelsThe array of strings. The strings and the array are copied.
paletteThe palette used to draw the object.

§ IlvListLabel() [2/2]

IlvListLabel::IlvListLabel ( IlvDisplay display,
IlUInt  count,
const IlvPoint position,
  ... 
)

Creates an IlvListLabel graphic object from a series of strings.

The variable part of the parameter list must contain exclusively count character strings. The strings are copied.

Parameters
displayThe display instance.
countThe number of strings given in parameter.
positionThe position of the graphic object bounding box.

Member Function Documentation

§ addLabel()

void IlvListLabel::addLabel ( const char *  label)

Adds a string.

Adds the specified string to the array of drawn strings at the last position.

Parameters
labelThe string to add. The string is copied.

§ align() [1/2]

IlvPosition IlvListLabel::align ( IlvPosition  align)

Sets the alignment of the strings.

Changes the alignment of the drawn strings.

Parameters
alignSpecifies the alignment.
Returns
The value of the parameter align.

§ align() [2/2]

IlvPosition IlvListLabel::align ( ) const

Returns the alignment of the strings.

Returns
The alignment of the drawn strings.

§ applyTransform()

virtual void IlvListLabel::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.

§ boundingBox()

virtual void IlvListLabel::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()

IlBoolean IlvListLabel::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.

§ draw()

virtual void IlvListLabel::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.

§ getCardinal()

IlUInt IlvListLabel::getCardinal ( ) const

Returns the number of label strings.

Returns
The number of strings drawn by the graphic object.

§ getLabel()

const char* IlvListLabel::getLabel ( IlUInt  index) const

Returns the string at a given index.

Returns
The string stored at the given index in the internal array of strings stored by the graphic object.
Parameters
indexThe index in the array of strings.
Note
The returned string must not be modified or deleted.

§ getLabels()

const char* const* IlvListLabel::getLabels ( IlUInt count) const

Returns the array of strings.

Returns
The array of strings drawn by the graphic object. The returned array and the strings must not be deleted or modified.
Parameters
countUsed to return the number of strings in the array.

§ getSpacing()

IlvDeltaPos IlvListLabel::getSpacing ( ) const

Returns the vertical spacing between lines.

Returns
The vertical spacing between drawn strings.

§ getText()

const char* IlvListLabel::getText ( ) const

Returns the contents of an array of strings.

Returns
A string composed of all the label strings drawn by the graphic object, each separated by a "`\n`" character.

§ inside()

IlBoolean IlvListLabel::inside ( const IlvRegion r,
const IlvTransformer t = 0 
) const
virtual

Determines whether an object with transformation applied is inside the bounding box.

Determines whether an object with transformation applied is inside the bounding box.

Parameters
rThe region to be tested.
tA transformer value, or 0 if there is no transformation.
Returns
IlTrue when the object, drawn with the transformer t, covers completely the region r. This member function returns IlFalse when this is not the case. That means that it returns IlTrue if all rectangles that define the region completely lie inside the object.

Reimplemented from IlvGraphic.

§ intersects()

IlBoolean IlvListLabel::intersects ( const IlvRegion r,
const IlvTransformer t = 0 
) const
virtual

Checks whether a region intersects the bounding box with transformation applied.

Checks whether a region intersects the bounding box with transformation applied.

Parameters
rThe region to be tested.
tA transformer value, or 0 if there is no transformation.
Returns
IlTrue when the region r overlaps the transformed object (if t is not 0) and IlFalse when this is not the case.

Reimplemented from IlvGraphic.

§ removeLabel()

void IlvListLabel::removeLabel ( IlUInt  index)

Removes the string at a given index.

Removes the label at the specified index from the array of drawn strings.

§ setFont()

virtual void IlvListLabel::setFont ( IlvFont font)
virtual

Sets the font of the object.

Parameters
fontThe new font.

Reimplemented from IlvSimpleGraphic.

§ setLabel()

void IlvListLabel::setLabel ( const char *  label,
IlUInt  index 
)

Sets a label string at a given index.

Replaces the string at the given index by a new one. The previous one is deleted.

Parameters
labelThe new label string. The string is copied.
indexSpecifies the index in the internal array of strings.

§ setLabels()

void IlvListLabel::setLabels ( const char *const *  labels,
IlUInt  count,
IlBoolean  copy = IlTrue 
)

Sets the array of strings.

Replaces the array of strings by a new one. The old array and its strings are deleted.

Parameters
labelsThe new array of strings.
countThe number of strings in the new array.
copyIf IlTrue, a copy of the strings and a copy of the array holding them is made. Otherwise, the graphic object directly uses the array of strings passed in argument.

Resets the graphic object with a multiline string.

Resets the object by extracting from text the substrings separated by a "`\n`" character.

§ whichContains()

IlInt IlvListLabel::whichContains ( const IlvPoint p,
const IlvTransformer t = 0 
) const

Returns the index of the string containing a given point.

Returns
-1 if the point is not in the graphic object. Otherwise, it returns the index of the drawn string containing the point.
Parameters
pThe point, possibly transformed.
tIf a transformer is specified, it is applied to the graphic object before testing if it contains the point.

§ zoomable()

virtual IlBoolean IlvListLabel::zoomable ( ) const
