Detailed Description

Graphic class.

Library: views

An IlvShadowLabel object appears as an IlvShadowRectangle containing a text string that is clipped by the containing rectangle.


- IlvShadowLabel -

Constructor & Destructor Documentation

IlvShadowLabel::IlvShadowLabel ( IlvDisplay display,
const char *  label,
const IlvRect rect,
IlUShort  thickness = IlvDefaultShadowThickness,
IlvPosition  shadowPosition = IlvBottomRight,
IlvPalette palette = 0 
)

Constructor.

Parameters
displayThe display instance.
labelThe character string drawn by the graphic object.
rectSpecifies the size of the filled rectangle around the string. This does not include the shadow of the object.
shadowThicknessThe shadow thickness.
shadowPositionThe shadow position.
paletteThe palette used to draw the graphic object.
IlvShadowLabel::IlvShadowLabel ( IlvDisplay display,
const IlvPoint at,
const char *  label,
IlUShort  thickness = IlvDefaultShadowThickness,
IlvPosition  shadowPosition = IlvBottomRight,
IlvPalette palette = 0 
)

Constructor.

This constructor allows you to specify the position of the center of the string label. The object computes its size to hold the label string.

Member Function Documentation

virtual void IlvShadowLabel::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 which might have the value 0. The clip parameter, which can also be 0, represents the clipping region relative to the transformed object.

Parameters
dstThe destination port.
tThe transformer value. If 0, no transformation is performed.
clipThe clipping region, or 0 if none.

Reimplemented from IlvFilledRectangle.

const char* IlvShadowLabel::getLabel ( ) const

Returns the string drawn by the graphic object.

Returns
the string displayed by this object. You must not modify or delete the returned string.
virtual void IlvShadowLabel::print ( ILVSTDPREF ostream &  out,
int  level = 0 
) const
virtual

Prints for debugging purposes.

Use for debugging purposes. Depending on the debugging level given as the level parameter, basic information about this object is printed to out. Basic implementation prints the object class name, and its bounding box. When this object is defined by another object (that is, if it is a referenced object), this subobject is described only if the level parameter is not zero. When this object is defined by a group of objects, these subobjects are defined themselves if the level parameter is not zero. In general, the higher level is, the more information you get about the object.

Parameters
outThe output stream.
levelThe debugging level. If 0, subobjects are not described.

Reimplemented from IlvGraphic.

virtual void IlvShadowLabel::setFont ( IlvFont font)
virtual

Sets the font of the object.

Parameters
fontThe new font.

Reimplemented from IlvSimpleGraphic.

void IlvShadowLabel::setLabel ( const char *  s)

Sets the string drawn by the graphic object.

Sets the string drawn by the graphic object. The previous string is deleted.

Parameters
labelThe new string. This string is copied.
