Detailed Description

Graphic related class.

Library: views

The IlvValue class allows you to query and change the values of a graphic object. Instances of this class are used in the IlvGraphic::queryValue and IlvGraphic::changeValue methods.
An IlvValue instance is defined by three things:

the accessor name, for example "label" to access the label of a button,
a value,
a type that corresponds to the type of the value.

To query a value from a graphic object, you create an instance of IlvValue with the name of the accessor and call the IlvGraphic::queryValue method. This method fills the value of IlvValue with a copy of the value inside the graphic object.
To change the value of a graphic object, create an instance of IlvValue with the name of the accessor and a new value, and pass this IlvValue to the IlvGraphic::changeValue method.

Warning: [note] When initializing an IlvValue with a numeric constant, ensure that the type of the constant is explicitly mentioned, or the numeric constant will default to IlBoolean with the value IlFalse or IlTrue.
For example, if you use the expression IlvValue v("x", 10); the value's type defaults to IlBoolean, thus 10 becomes IlTrue. To keep the value 10, this expression should be replaced with the following:
IlvValue v("x", (IlInt)10);

or better:
const IlInt position = 10;

IlvValue v("x", position);

The possible types for an IlvValue are:

IlvValueNoType for empty IlvValue
IlvValueIntType for IlInt value
IlvValueUIntType for IlUInt value
IlvValueStringType for char* value
IlvValueBooleanType for IlBoolean value
IlvValueColorType for IlvColor value
IlvValueFontType for IlvFont value
IlvValuePatternType for IlvPattern value
IlvValueColorPatternType for IlvColorPattern value
IlvValueGradientPatternType for IlvGradientPattern value
IlvValueLineStyleType for IlvLineStyle value
IlvValueFillStyleType for IlvFillStyle value
IlvValueFillRuleType for IlvFillRule value
IlvValueArcModeType for IlvArcMode value
IlvValueAntialiasingModeType for IlvAntialiasingMode value
IlvValueDirectionType for IlvDirection value
IlvValueBitmapType for IlvBitmap value
IlvValueFloatType for IlFloat value
IlvValueDoubleType for IlDouble value
IlvValueStringArrayType for arrays of char*
IlvValueUIntArrayType for arrays of IlUInt
IlvValueMenuItemArrayType for arrays of IlvMenuItem
IlvValueMatrixItemArrayType for arrays of IlvMatrixItems
IlvValueNotebookPageArrayType for arrays of IlvNotebookPage

The possible values for the accessors are described in each class where accessors are defined.
