Detailed Description

Encapsulates one data cell in a chart.

Data cells either hold one value for the ordinate axis or they hold two values: one for the ordinate axis and an extra one for the abscissa axis.

Ordinate values can either be of type double or non-existant, abscissa values can either be of type double or TQDateTime or non-existant.

Note: All methods returning one of the data values (or one of the data types, resp.) expect a valNo parameter with either a 1 for the first value (the Y or ordinate value) or a 2 for the second value (the X or abscissa value).

Definition at line 134 of file KDChartDataIntern.h.

Member Function Documentation

◆ clearValue()

void KDChartData::clearValue ( )

inline

Resets both of the data types of this cell to KDChartData::NoValue and sets the property set ID to KDCHART_PROPSET_NORMAL_DATA.

Definition at line 329 of file KDChartDataIntern.h.

◆ dateTimeValue()

TQDateTime KDChartData::dateTimeValue ( int valNo = 1 ) const

inline

Returns the TQDateTime value represented by this object, or TQDateTime() if this object does not represent a TQDateTime value.

You may use isDateTime() to check if it is appropriate to call this function.

Returns: the TQDateTime value represented by this object, or TQDateTime() if this object does not represent a TQDateTime value

Definition at line 378 of file KDChartDataIntern.h.

◆ doubleValue()

double KDChartData::doubleValue ( int valNo = 1 ) const

inline

Returns the double value represented by this object, or DBL_MIN if this object does not represent a double value.

You may use isDouble() or isNormalDouble() to check if it is appropriate to call this function.

Returns: the double value represented by this object, or DBL_MIN if this object does not represent a double value

Definition at line 372 of file KDChartDataIntern.h.

◆ hasValue()

bool KDChartData::hasValue ( int valNo = 1 ) const

inline

Returns true if the object represents a value (double or TQString) and false otherwise.

Returns: true if the object represents a value

Definition at line 302 of file KDChartDataIntern.h.

◆ isDateTime()

bool KDChartData::isDateTime ( int valNo = 1 ) const

inline

Returns true if the object represents a TQDateTime value and false otherwise.

Returns: true if the object represents a TQDateTime value

Definition at line 321 of file KDChartDataIntern.h.

◆ isDouble()

bool KDChartData::isDouble ( int valNo = 1 ) const

inline

Returns true if the object represents a double value and false otherwise.

Returns: true if the object represents a double value

Definition at line 315 of file KDChartDataIntern.h.

◆ isEqual()

bool KDChartData::isEqual	(	const KDChartData &	a,
		const KDChartData &	b
	)		const

inline

Compare method.

Note: The property set ID is not taken into account while comparing. Two KDChartData are considered equal if their data values are equal - the property set ID is ignored.

Definition at line 195 of file KDChartDataIntern.h.

◆ isString()

bool KDChartData::isString ( int valNo = 1 ) const

inline

Returns true if the object represents a TQString value and false otherwise.

Returns: true if the object represents a TQString value

Definition at line 309 of file KDChartDataIntern.h.

◆ operator!=()

bool KDChartData::operator!= ( const KDChartData & it ) const

inline

Compare operator.

See also: isEqual

Definition at line 183 of file KDChartDataIntern.h.

◆ operator==()

bool KDChartData::operator== ( const KDChartData & it ) const

inline

Compare operator.

See also: isEqual

Definition at line 173 of file KDChartDataIntern.h.

◆ propertySet()

int KDChartData::propertySet ( ) const

inline

Return the ID of the property set that is assigned to this data cell.

Use KDChartParams::properties( int ID ) for accessing the respective property set information.

See also: setPropertySet; KDCHART_PROPSET_NORMAL_DATA, KDCHART_PROPSET_TRANSPARENT_DATA

Definition at line 409 of file KDChartDataIntern.h.

◆ setAll()

void KDChartData::setAll ( const KDChartData & R )

inline

Method setAll.

Note: The property set ID is also changed by the setAll method.

See also: setData

Definition at line 246 of file KDChartDataIntern.h.

◆ setData()

void KDChartData::setData ( const KDChartData & R )

inline

Method setData.

Note: The property set ID is not changed by the setData method. If you want to set it please call KDChartData::setPropertySet() explicitely.

See also: setAll

Definition at line 261 of file KDChartDataIntern.h.

◆ setPropertySet()

void KDChartData::setPropertySet ( int propSetID = 0 )

inline

Assign a property set to a data cell.

Parameters

propSetID The ID of the property set to be assigned to this data cell. This ID can either be one of the built-in IDs documented at KDChartPropertySet::BuiltinDataPropertySetIDs or a special ID that was given back by a KDChartParams::registerProperties function call.

See also: propertySet; KDCHART_PROPSET_NORMAL_DATA, KDCHART_PROPSET_TRANSPARENT_DATA

Definition at line 397 of file KDChartDataIntern.h.

◆ stringValue()

TQString KDChartData::stringValue ( int valNo = 1 ) const

inline

Returns the string value represented by this object, or TQString() if this object does not represent a string value.

You may use isString() to check if it is appropriate to call this function.

Note: String values may be used to store axis labels or legend texts in extra data cells.

Returns: the string value represented by this object, or TQString() if this object does not represent a string value

Definition at line 363 of file KDChartDataIntern.h.

◆ value()

TQVariant KDChartData::value ( int valNo = 1 ) const

inline

Definition at line 336 of file KDChartDataIntern.h.

◆ valueType()

KDChartData::ValueType KDChartData::valueType ( int valNo = 1 ) const

inline

Returns the type of the respective value.

Parameters

valNo specifies the value number: 1 means the Y value, 2 means the X value

Returns: the type of the respective value
